CAC - Chair of Applied Cryptography

Theses (Bachelor/Master)

We offer thesis topics related to cryptography, IT security and Blockchain technologies. Our major areas of research are:

• Hardware cryptography: for example, designing new cryptographic primitives that are provably secure against side-channel attacks, analyzing existing countermeasures and benchmarking their efficiency.
• Scalability of blockchains: for example, investigating how to improve the efficiency and transaction throughput of blockchain technology.
• Security of blockchain: for example, attacking the privacy or robustness of existing cryptocurrencies.
• Cryptographic protocols: for example, designing cryptographic protocols that guarantee fairness by using smart contracts, or preserve privacy by using zero-knowledge proof systems.

We offer both more theoretical and applied thesis topics. A theoretical thesis may include a literature survey, security models and a formal security analysis of a security/cryptographic/blockchain protocols. In a more applied thesis you will implement new primitives and protocols and benchmark their performance (according to various measures). Alternatively, you may also try to attack existing cryptographic/security/blockchain systems.

TOP 6 RESEARCH TOPICS IN CRYPTOGRAPHY

Cryptography refers to the methodology which is involved in establishing safe communication and ensuring data privacy. When messages are transformed into unperceivable content using cryptographic tools, they cannot be easily retrieved by attackers.  If you are facing any issues about your projects in cryptography then continue to read this article on research topics in cryptography.

Generating cryptographic keys, surfing over the web, establishing secure communication for instance financial transactions and personal mails, digital key signing, data protection, and verification are some of the major domains in which the algorithms of cryptography are used extensively. 

Here you can get an ultimate overview of cryptography research from the very basics. First, let us understand cryptography

What is cryptography?

• Cryptography generally denotes the procedure involved in the conversion of usual data into indistinguishable information in a motive to protect it
• Also the conversion of highly protected imperceptible data into normal text form a part of cryptography
• Cryptography is of great significance in most of the everyday applications such as online electronic financial transactions and securing passwords etc.
• Usually three kinds of cryptography methods are used at large

To get detailed descriptions and research-oriented explanations on various Cryptography methods you can reach out to our experts at any time. With a world-class reputation, experts at research topics in cryptography have earned the confidence of students from more than one hundred and fifty countries of the world. 

The crystal clear explanations of the mechanisms and principles behind the working of cryptography have gained us global recognition. If you are looking to get expert assistance for your Cryptography projects then you need to surely check out our website. We will now talk about the working of cryptography

How does cryptography work?

• Safe communication establishment amid third party interruptions by rivals is the major goal of cryptography
• Proper algorithms and appropriate keys are deployed for transforming plain text data input to cipher text-based encrypted output
• Identifying and authenticating participants
• Critical data encryption
• Unchangeable record creation involving permanent audit attempts
• Security of the tools and techniques in cryptography
• Cryptographic methodological complexities

Hence standard and highly reliable research support is essential to understand in more depth the tools, protocols, and software for establishing successful cryptography research projects . For this purpose, you can readily reach out to our experts who have guided an ample number of highly successful research topics in cryptography . So we are capable of handling any Visual Cryptography project . Let us now look into the principles behind the working of cryptography

What are the principles of cryptography?

The following are the key principles involved in cryptography for ensuring data transmission security demands

• Since the Identity of both sender and receiver are revealed, one cannot deny any action of transmission that has been performed
• The proof of both transmission and reception disable is a person from disowning or repudiation
• A sender can usually authenticate the receiver with his or her particular identity
• Since the identity of both the parties are validated efficiently, there is no room for missing out on the authentication
• Cryptography also provides for an approach wherein a receiver can surely authenticate the messages received
• Hence tampering of messages cannot be entertained
• Only the authenticated user or receiver can read the data
• Data can therefore be protected from Eavesdropping attacks

Keys play an important role in ensuring the secrecy and privacy of encrypted data in cryptosystems . Hence make sure that you protect the keys used in your project. All the encryption keys should never be stored in plain text in association with their respective protected data. If you do so, then it is the same as leaving the front door closed with keys on it. We are well known for such easily understandable analogies-based explanations in cryptography. The following methodologies are used commonly for key protection purposes thus ensuring greater security. 

• Scrypt, bcrypt, and PBKDF2 are the algorithms that are used for both password generation and bootstrapping the cryptosystem
• It is important to note that the password has to be very strong and known only to a few administrators
• By doing all these you can ensure that unencrypted keys can be stored in any place
• You can use Access Control Lists that are strong for protecting keys and storing them in file systems. The least privilege principle has to be followed for more security
• Coding can be used to establish API calls to the hardware security module
• As a result proper keys are provided at times of necessity and performing data decryption on the hardware security module becomes easy

Such suitable and proven methods are developed and compiled by our experts to make your cryptography project experience more interesting and informative. Therefore you can get access to authentic and reliable data needed for your projects from our experts.

End-to-end encryption (E2EE) is now the norm for Internet browsing (via TLS) and increasingly also for messaging (with apps such as WhatsApp and Signal being end-to-end encrypted by default). Somewhat surprisingly, services that offer outsourced data storage, such as cloud storage and collaborative file editing platforms, still lag behind. One of the explanations might be the complexity that arises due to the persistence of data, which makes it difficult to use ephemeral key material to achieve strong security guarantees such as forward secrecy (FS) and post-compromise security (PCS). Another is the lack of a formal security models for even basic E2E security of outsourced data storage supporting functionality such as file sharing between users. In particular, the number of potential end-points arising from file sharing increases the complexity of E2EE cloud storage compared to single client settings. This complexity also exists in messaging, as showcased by the fact that protocols for secure two-party messaging (such as e.g. the Signal protocol) have been around for quite some time, but a protocol for E2EE group chats was only very recently standardized [rfc9420]. The newly standardized group messaging protocol is called "messaging layer security" (MLS). One of the main motivations for MLS was to make E2E security for messaging in groups of size n more efficient than through the naïve construction of n^2 two-party channels, while still retaining the same high-security guarantees—including forward secrecy and post-compromise security—that we expect from modern secure messaging protocols. In this project, we will explore the possibilities for more advanced security guarantees for file sharing systems in the E2EE setting. In particular, we will aim to tackle the conflict between the required functionality (including persistent data access, and flexible group and access management) and strong security guarantees such as FS and PCS. Our initial attempt at a solution, which we call the "secure shared folder" (SSF) scheme, combines the recent advancements of group messaging from the MLS standard with a form of key ratcheting known as key regression [NDSS:FuKamKoh06]. The aim of this project is to test the practicality of the SSF scheme by implementing a proof of concept file sharing system based on this cryptographic design.

VPNs provide increased privacy to users, and are therefore commonly used to circumvent censorship. In response, certain censoring bodies have begun using more advanced traffic analysis to block VPN access. There are two main strategies for VPN blocking: blocking by address (IP addresses of a VPN service), and blocking by behaviour (identifiable characteristics of the VPN traffic). VPN fingerprinting is the process of identifying a particular VPN protocol based on its protocol features. As is common in the cat-and-mouse game of defences and attacks, circumvention developers have created new protocols intended to protect against such fingerprinting. Several VPN protocols have implemented advanced protocols for the sake of circumventing this style of fingerprinting. This project aims to determine the efficacy of these circumvention techniques, by evaluating two advanced deployments of VPN protocols for censorship circumvention: Outline VPN [Out20,RM23] and LEAP VPN [Lea22]. Both Outline and LEAP offer client and server-side tools to enable individuals as well as organisations to act as service providers. These tools utilise and build on a number of existing technologies, from OpenVPN and Shadowsocks to Tor and Snowflake, which have previously been studied only in isolation [FWW20]. The project involves providing accurate and holistic abstractions of the systems and protocols and then applying a combination of fingerprinting [XKHE23, XRJ22], cryptanalysis, and machine learning techniques to determine if the protocols have identifiable features. We focus on exploring the capabilities of VPN fingerprinting for the sake of developing stronger censorship-resistant protocols in the future.

(Supervisor: Prof. Kenny Paterson, Joint Supervisor: Kien Tuong Truong) Cloud storage providers such as Dropbox, Google Drive and Microsoft OneDrive allow users to offload their digital storage requirements to a remote server, managed by the provider. This is convenient and can create cost savings for both individuals and organizations. All of these providers consider security against attacks from outsider threats. However, few providers address security when the server itself is compromised, and some of those that do have been shown to have devastating cryptographic vulnerabilities, as evidenced by the attacks on Mega [BHP23] and Nextcloud [CPAB23]. Even if there were existing solutions that provably provided confidentiality and integrity of files, metadata is still often leaked. As an example, some providers leak file names. As another example, the server is always aware of the access patterns of the users. All these leakages can combine to create attacks which can compromise the privacy of users. A significant problem is that, even though a multitude of end-to-end encrypted (E2EE) cloud storage solutions exist on the market, there is a lack of foundational work on the cryptographic design for such systems. In order to guide such work, we look at the current ecosystem of E2EE cloud storage solutions, analyzing their protocols, and discussing their requirements. A new cloud storage solution that promises to protect the security and privacy of users is PrivateStorage [Aut] by Least Authority [lea]. Much like MEGA and Nextcloud, they claim to provide end-to-end encryption. However, they also implement unique features like accountless authorization, which they implement with a bespoke variation of Privacy Pass [Dav18]. This mechanism allows users to access the service without the need for a traditional account, decoupling service usage from identifiable information (e.g. payment information), and thus enhancing user privacy. This should ensure protection against surveillance, invasive data analysis and profiling, even if the adversary is a nation-state actor. PrivateStorage’s model offers a promising solution that could set new standards for the industry. However, new designs and the new cryptographic and privacy related protocols always raise concerns about potential vulnerabilities. This thesis seeks to analyze the protocol in order to find possible issues or, if none are found, to prove (a selection of) the claims given by PrivateStorage. References: [Aut] Least Authority.

In light of the mass surveillance and censorship going on in many countries, there has been continued interest in providing tools that enable their users to communicate securely and privately. This is of particular importance to groups of higher-risk users (e.g., political activists). Decentralised messaging applications offer promising solutions for such users because they do not require a central server in the middle to forward messages or manage data, thus removing a potential single point of failure as well as making it harder for communications to be monitored. Despite the strong security claims made by the designers of decentralised messaging applications, many of them employ custom cryptographic protocols and justify their security claims using only informal arguments or by way of partial code audits that only check for common vulnerabilities. Hence, it is unclear what security guarantees are provided in reality. Researchers studying these protocols often find cryptographic vulnerabilities in them, even after supposed fixes and code audits, which is illustrated in the example of Bridgefy [ABJM21, AEP22, 7AS23] and Matrix [ACDJ23]. This shows the importance of performing formal security analyses of decentralised messaging applications. Two decentralised messaging applications in particular are of core interest because they both have generally positive track records from past security audits, but their custom cryptographic protocols have yet to receive any formal security analysis. external page Delta Chat call_made  is a messaging application that builds on the existing email infrastructure. There is no central server unless all users come from the same email provider. It offers end-to-end encryption using external page Autocrypt call_made and external page CounterMITM call_made protocols, which use a subset of the OpenPGP standard. external page Briar call_made is a messaging application designed for activists, journalists, and anyone else who needs a safe, easy and robust way to communicate. Briar users can synchronize messages directly between contacts via Bluetooth, WiFi, or Tor. Our semester project [Son23] argues informally that Briar's custom cryptographic protocols are overall secure. The main objective of the project is to make a deep-dive on Delta Chat and Briar, with the primary aim of conducting a formal security analysis of their cryptographic protocols. This entails analysing their cryptographic components as well as the composition of these components and various subprotocols that the applications rely on.

While core cryptographic protocols such as TLS and Signal have received significant attention from the cryptographic research community, there are many products, apps, and protocols out there "in the wild" that rely on cryptographic mechanisms to protect their users that remain understudied. In particular, the amount of data stored on the cloud is projected to reach 200 Zettabytes by 2025 [Arc20], which makes cloud storage an interesting target for attackers who want access to personal data. Encryption-at-rest and encryption-in-transit can only provide a limited amount of security, given that advanced attackers (such as nation-state attackers) can actively compromise servers and thus gain access to user data. End-to-end encrypted (E2EE) cloud storage promises to allow users to keep control of their data, even when outsourcing it to the cloud. However, recent attacks on Mega [BHP22] and NextCloud [CPAB23], along with the general lack of a formal model in the literature, have raised some doubts about the security of existing implementations. Our objective is to investigate and analyse the cryptography used by other cloud storage solutions. The focus will be on applications that serve numerous or important organizations, making a possible vulnerability impactful for a large amount of users. As an example, the analysis can focus on products such as Tresorit and Sync. In more detail, we will try to understand the inner workings of the systems and provide accurate abstractions of the discovered systems and protocols. Using these abstractions, we will look for security weaknesses in these systems and/or produce security proofs for those abstractions. Any weaknesses discovered will be documented carefully, and disclosed to the affected vendors according to standard responsible disclosure practices. Our focus will be on describing how the different systems operate, what security issues were found, and (if time permits) how they were remediated.

While core cryptographic protocols such as TLS and Signal have received significant attention from the cryptographic research community, there are many products, apps, and protocols out there "in the wild'' that rely on cryptographic mechanisms to protect their users that remain understudied.

The main focus of this thesis will be RocketChat, a team collaboration platform similar to Slack. RocketChat is open source and promises end-to-end encryption as well as the option of self hosting. This is a combination that is rare amongst it’s direct competitors. This has lead to adoption specifically by customers that by the nature of their business value confidentiality, such as banks (World Bank), insurance companies (Lloyd's), government agencies (US Department of Homeland Security, indirectly), but also more generally, e.g. Audio and Deutsche Bahn.

The main objective of this project is to take a deep dive into RocketChat and analyse their cryptography and its integration into a complex system from both a design aspect as well as an implementation aspect. Since RocketChat does not come with a detailed formal description of their cryptography, this will have to be derived from the existing implementation. RocketChat also has several different end-to-end encryption implementations with different security claims, as well as some integration with the Matrix protocol as part of federated rooms, resulting in a large surface for design and implementation aspects to go wrong.

Thesis projects and finished theses with the cryptology and data security research research group at the University of Bern and in the Swiss Joint Master in Computer Science .

Thesis topics are related to our research and offered courses .

Many projects address theory and practice of cryptology and data security; some are purely theoretic but very few are only of practical nature.

Available projects for BSc and MSc theses

The indication of a BSc or MSc project type may be discussed and a smaller version of a project labeled MSc may often be carried out as a BSc thesis.

Many more projects in the research domain of the group are possible. If you would like to suggest a topic for a thesis project, please contact a team member to discuss your idea.

These projects are intended for computer-science students at the University of Bern and those enrolled in the Swiss Joint Master of Science in Computer Science . We do not offer any internships.

Current thesis projects

Completed thesis projects, instructions and templates for theses.

Once you have agreed with your supervisor on a topic and on a start- and end-date, fill in the corresponding form and complete the respective procedure:

For a BSc thesis, the form is available from the Studienfachberatung .

For a MSc thesis, follow the JMCS process .

Presentation

Every thesis must be presented near the completion or at the end of the project. Usually this occurs during the semester, within the regular seminar organized by the Cryptology and Data Security group. BSc students must also attend the seminar as a regular participant and get credit for it. The seminar’s title may vary; see the course page for details. You should agree with your supervisor in the initial stage of the thesis on where and when to present your work.

For archiving software and thesis report, log in once to the INF gitlab server with your Campus Account (small login box at the bottom). This creates your user representation inside the server. Then ask your supervisor to create a repository for the project under the group crypto-students according to the pattern:

For a seminar report you may use the sample article template used by the CRYPTO group .

For a BSc thesis a sample template is available on the Cryptography and Data Security group website .

For a Msc thesis, the sample template is available on JMCS website .

The final version of a thesis consists of a single PDF file. Printed copies are not needed. This file must also contain the signed declaration (“Erklärung”) , in which the candidate confirms that she/he personally authored the work. (Print, sign, scan, and include the declaration at the end of the thesis.)

Research advice

Computer-science research can, roughly, be divided into “systems” and “theory” projects.

In systems research, one builds, experiments, and measures. Research results are typically demonstrated through an evaluation. However, measuring the behavior of a complex system is tricky. If you measure anything in your project, then you should read and follow this useful resource:

• Always Measure One Level Deeper ( PDF Format ), authored by John Ousterhout, a distinguished systems researcher at Stanford University.

Theoretical research demonstrates its insight in abstract form, through algorithms, protocols, and (crypto)schemes described abstractly in the computer-science dialect of the language of mathematics. Here, results are typically demonstrated through proofs. If you author a theoretical thesis, then you should read and follow some advice on mathematical writing, such as:

Mathematical Writing by Knuth, Larrabee, and Roberts ( PDF Format ). Read points 1-27 on pages 1-6.

Many guides to mathematical writing can be found online. Pick one that you like.

Writing advice

Theses are written in English. Refer to a manual of style for guidance on writing scientific texts. You should read and follow at least the first two.

Advice on writing in computer science , published by Renée Miller of the University of Toronto, is a concise summary with pointers to more material.

The BSc thesis template explains how to assemble and format the bibliography using BibTeX.

Advice on Writing, Presentation & Plagiarism from the JMCS programme.

The Elements of Style by Strunk and White is a classic style guide (it even has its own Wikipedia page!) and one can find versions online .

After finishing the thesis, some forms have to be processed:

For BSc, the advisor completes the form and hands it to the Studiensekretariat.

For MSc, you fill in parts “Finishing…” and “Pledge…” on the back of the JMCS form for MSc theses and hand this to the Studiensekretariat at Uni BE. The advisor the completes the JMCS form, fills the form of Uni BE, and hands both to the respective recipients.

Finally, follow the steps to graduate .

Overview of Cryptography and Network Security

Cryptography  is basically classified into two major techniques, and they are cryptography and cryptanalysis. On the one hand,  cryptography  is the process of protecting or hiding the information through intelligent masking techniques (i.e., code the information). On the other hand,  cryptanalysis  investigates how the ciphertext is converted into plain text and vice-versa.

Due to its incredible security concern and contribution, it is largely used in many research domains and areas to improve its security aspects. Some of the current research aspects of cryptography are given as below,

• Hashing Techniques
• Public-Key Cryptography
• Key Distribution and Management
• Symmetric-Key Cryptography
• Real-time Cryptography Applications
• Cryptographic Security Protocols / Standards
• Quantum Cryptography
• Biological Cryptography
• And many more

Network Security  is intended to develop various levels of shielding measures with an extended security scope. These measures are worked in the principle of identifying/predicting network security threats/risks to take immediate defensive response/actions. As a result, it protects the entire network information. The identification, prediction, and defensive response measures are essential to execute based on specific security policies . Few of the current research directions of the network security are given as below,

• Incident Response System
• Intrusion Detection and Prevention Schemes
• Trusted Heterogeneous Networks
• Network Security Threats, Risks and Vulnerabilities
• Network Protection against Internet Attacks
• Communication Technologies and Protocol Security

We hope you are clear on the fundamentals of cryptography and network security . Now, we can see the recent research areas of cryptography and network security . In truth, our research team is presently creating unbelievable contributions through our latest research topics in cryptography and network security . So, you can confidently hold your hands with us to create amazing research work.

Research Gaps of Cryptography

Though many lightweight ciphers are introduced in cryptography, it lacks performance in any of these aspects, such as high security and low ( resource utilization, delay, internal overhead states , etc.).

Below, we can see the challenges in lightweight cryptographic techniques such as elliptic curve cryptography, stream ciphers, hash methods, and block ciphers . Our developers will pay extra attention to the following for framing lightweight security measures that assure high performance in all aspects.

CRYPTOGRAPHY LATEST ALGORITHMS

• Decrease the usage of energy / power
• Minimize the needs of memory

• Test the vulnerabilities of the of the network at different angles through continuous scan and access
• Probe the available susceptibilities in the application and take immediate response to that events
• Analyze and troubleshoot the packets, network, applications, communication protocols and more
• Collect whole information of network including OS, computer systems, and network entities

Next, we can see about the secure transmission approaches. Basically, the performance metrics have a key player role in elevating the design of transmission approaches. However, it has high importance, the modeling of physical layer security cause different kinds of technical issues . So, it is critical to select the suitable metrics for improving reliability, resource cost (low power), transmission efficiency, and energy efficiency of the transmission approaches . Our developers will help to attain your goal in the following aspects of transmission approaches.

• Reliability – compute in terms of privacy outage probability and capacity
• Power cost – compute in terms of power usage (low) for promising QoS
• Transmission Efficiency – compute in terms of maximum possible privacy degree and capacity
• Energy Efficiency – compute in terms of amount of energy required for one bit transmission and amount of bits transmitted in one unit of energy

As mentioned earlier, the above-specified metrics are sure to increase the performance of transmission approaches. And, these metrics are adopted in the time of system modelling . Further, we have improved our skills in all security-related strategies based on recent research requirements.

Assuming that there will be efficient quantum computers in the "near" future, we want to investigate whether we can already make current protocols secure against quantum algorithms. The research area of post-quantum cryptography searches for secure cryptographic methods under the assumption that in the future a quantum computer can break the current methods. The danger of quantum algorithms is already real, as data can be stored and only later their encryption can be broken and thus the data can be read. This research area is not only about the secure use of these methods, but also about the transition in protocols from current cryptography to post-quantum cryptography. How do we construct cryptoagile quantum-resistant protocols?

In 2016, NIST (National Institute of Technology) declared a standardization process for post-quantum procedures. Supposed quantum-resistant algorithms are assumed to be based on lattice-, code-, and isogeny-based assumptions (and some more). The research area of post-quantum cryptography deals with the analysis of these primitives, exploration of further quantum-resistant methods and their use in theory and practice.

In the area of post-quantum cryptography, the first step is to build up a basic understanding of some underlying mathematical methods such as lattice cryptography.

Following this, we look at how far we can protect previously researched protocols against possible attackers with quantum computers. Here we replace individual primitives with primitives based on lattice-based assumptions, which are possibly quantum-resistant.

Another step also deals with cryptoagility within post-quantum protocols. Here there are different approaches and views on how the transition from the current -- called classical -- to the quantum-resistant -- called post-quantum -- cryptography can work in theory and practice without loss of security.

We offer a seminar "Post-Quantum Cryptography" every winter semester. In the research-oriented seminar, topics are selected from the standardization process for post-quantum cryptography of NIST. The algorithms are based on different mathematical, supposedly quantum-resistant methods: Lattices, Codes, Isogenies and some more. No prior knowledge is required for the seminar, but we expect a high level of self-motivation. In a series of introductory lectures all participants will be brought up to a basic level before selected topics will be worked on and presented by the students.

In addition, we offer post-quantum cryptography as a topic for student theses or for the module Practice of Research.
