Computer Science

Security and cryptography.

Securing the Internet presents great challenges and research opportunities. Potential applications such as Internet voting, universally available medical records, and ubiquitous e-commerce are all being hindered because of serious security and privacy concerns. The epidemic of hacker attacks on personal computers and web sites only highlights the inherent vulnerability of the current computer and network infrastructure.

Adequately addressing security and privacy concerns requires a combination of technical, social, and legal approaches. Topics currently under active investigation in the department include mathematical modeling of security properties, implementation and application of cryptographic protocols, secure and privacy-preserving distributed algorithms, trust management, verification of security properties, and proof-carrying code. There is also interest in the legal aspects of security, privacy, and intellectual property, both within the department and in the world-famous Yale Law school, with which we cooperate. 

Faculty working in this area:

Highlights in this area:

Joan Feigenbaum has conducted direction-setting research on various aspects of cryptography, security, and privacy for more than thirty years.  For example, she was the co-founder (with Matt Blaze and Jack Lacy) of the security-research area of “trust management.”  In 2020, Blaze, Feigenbaum, and Lacy won the IEEE Symposium on Security and Privacy Test-of-Time Award for their 1996 paper “Decentralized Trust Management.”  Currently, Professor Feigenbaum is working on “socio-technical” issues in the interplay of computer science and law, including the tension between strong encryption and lawful surveillance.

Ben Fisch will start at Yale in 2022 as co-director of the Yale Applied Cryptography Laboratory and Assistant Professor of Computer Science. He is broadly interested in problems related to privacy and verifiability in information systems, with a special attention on applications of cryptography to blockchains. He has worked closely with the blockchain industry, and his research has impacted open source projects including Filecoin, Ethereum, and Chia. His research has focused on various types of cryptographic proof systems, including zero-knowledge proofs, proofs of storage, proofs of correct computation, and verifiable delay functions. 

Michael Fischer is interested in security problems connected with Internet voting, and more generally in trust and security in multiparty computations. He has been developing an artificial society in which trust has a precise algorithmic meaning. In this setting, trust can be learned and used for decision making. Better decisions lead to greater social success. This framework allows for the development and analysis of some very simple algorithms for learning and utilizing trust that are easily implementable in a variety of settings and are arguably similar to what people commonly use in everyday life.

Charalampos Papamanthou is the co-director of the Yale Applied Cryptography Laboratory and an Associate Professor of Computer Science at Yale. Before Yale, he was the Director of the Maryland Cybersecurity Center (MC2) and an Associate Professor of Electrical and Computer Engineering at the University of Maryland, College Park, where he joined in 2013 after a postdoc at UC Berkeley. He works on applied cryptography and computer security—and especially on technologies, systems and theory for secure and private cloud computing. He has received the NSF CAREER award, the Google Faculty Research Award, the Yahoo! Faculty Research Engagement Award, the NetApp Faculty Fellowship, the UMD Invention of the Year Award, the Jimmy Lin Award for Invention, the George Corcoran Award for Excellence in Teaching and was also finalist for the 2020 Facebook Privacy Research award. His research has been funded by federal agencies (NSF, NIST and NSA) and by the industry (Google, Yahoo!, NetApp, VMware, Amazon, Ergo, Ethereum and Protocol Labs). His PhD is in Computer Science from Brown University (2011) and he also holds an MSc in Computer Science from the University of Crete (2005), where he was a member of ICS-FORTH. His work has received over 9,000 citations and he has published in venues and journals spanning theoretical and applied cryptography, systems and database security, graph algorithms and visualization and operations research.

Zhong Shao  leads the FLINT group at Yale, which is applying formal methods to complex security-sensitive systems in such a way that they can guarantee to users that these systems really are trustworthy.  There are several challenges standing in the way of achieving this goal. One challenge is how to specify the desired security policy of a complex system. In the real world, pure noninterference is too strong to be useful. It is crucial to support more lenient security policies that allow for certain well-specified information flows between users, such as explicit declassifications. A second challenge is that real-world systems are usually written in low-level languages like C and assembly, but these languages are traditionally difficult to reason about. A third challenge is how to actually go about conducting a security proof over low-level code and then link everything together into a system-wide guarantee.

Anurag Khandelwal is interested in building cloud-based systems that are secure by construction. His team is currently exploring the design of secure storage systems, where simply storing the data in an encrypted form is insufficient to ensure security: an adversary can launch powerful attacks that use data access patterns to learn damaging information about the data. Existing countermeasures against these attacks remain impractical at the scale of modern storage systems due to large bandwidth and/or storage overheads. His team is exploring how modeling access to the storage as a statistical distribution can enable significantly more scalable solutions that still retain formal security guarantees against practical adversarial settings.

Lin Zhong and his team are interested in the security and privacy of application data in the context of personal and cloud computing. Modern systems often assume the operating system as part of the trusted computing base and as a result, modern operating systems by design have unfettered access to application data. His team is exploring both incremental changes to existing operating systems, e.g., Linux, and clean-slate operating system designs to decouple virtualization, the essential role of operating systems, from data access. They are also exploring the use of machine learning, especially adversarial learning, to minimize privacy-sensitive information in data collected on mobile and IoT devices.

Administration

Phd students, motivation..

Cryptography is a crucial tool for securing information systems. Cryptographic building blocks ensure the secrecy and integrity of information, and help to protect the privacy of users. Still, most actually deployed cryptographic schemes are not known to have any rigorously proven security guarantees. This has led to a number of far-reaching security issues in widely deployed software systems.

Our goal is to provide practical cryptographic building blocks that come with rigorously proven security guarantees. These building blocks should be efficient enough for the use in large-scale modern information systems, and their security should be defined and formally analyzed in a mathematically rigorous manner.

Technical interests.

We are interested in the foundations of theoretical cryptography, and in general ways to derive constructions and security guarantees in a modular fashion. One research focus in our group concerns new cryptographic building blocks such as indistinguishability obfuscation, functional encryption, and fully homomorphic encryption. We are particularly interested in the design and analysis of cryptographic schemes in the public-key setting. This covers common tools like public-key encryption and digital signatures, specifically in realistic modern scenarios (such as settings with adaptive adversaries, and a huge number of users).

This information concerns the “Digital Signatures” lecture in the Spring 2023 semester at ETH. The content for this course will be provided through Moodle.

This information concerns the “Information Security” lecture in the Spring 2023 semester at ETH. The content for this course will be provided through Moodle.

Available Theses

Learning Parity with Noise is a mathematical problem on whose intractability several advanced cryptographic primitives are based. While LPN is similar to Learning With Errors it has received less attention than its lattice-based pendants. However, there are signs that some cryptographic primitives can be achieved by LPN, but not by LWE (Indistinguishability Obfuscation and VOLE e.g.). In this thesis, we will study a variation of LPN that is given over large fields (instead of bits). Our aim is to find new subexponential attacks on LPN, where we put our focus on algebraic attacks. A student interested in this thesis should have some basic knowledge in commutative algebra (polynomial rings and ideals).

• Compressing Vector OLE The Hardness of LPN over Any Integer Ring and Field for PCG Applications

Meta-complexity is an exciting field that provides intriguing insights into how computation fundamentally works. In particular, meta-complexity techniques have established some interesting results between complexity theory and cryptography (see [1] ) and seem promising in ruling out some of Impagliazzo's five worlds (see [2] ). The goal of this project is to survey the existing literature on meta-complexity, in particular in connection to the theory of cryptography. A student interested in this topic should have a strong background and interest in theoretical computer science ("Theoretische Informatik" or an equivalent basic TCS course). Knowledge of cryptographic principles is beneficial but not strictly necessary.

• [1] On the Possibility of Basing Cryptography on BPP =/= EXP [2] A Personal View of Average-Case Complexity

A puncturable signature scheme is a special type of digital signature. It allows a signer to update their signing key sk to sk* such that certain message(s) become unsignable. This turns out to be a useful property in applications such as Proof-of-Stake based blockchains or asynchronous transaction data signing services. The goal of the thesis is to review existing definitions and constructions, understand their advantages and drawbacks, and propose new constructions. Depending on the interest of the candidate, this could either be interesting theoretical constructions or rather constructions with properties useful in practical applications. A student interested in this topic should have basic knowledge of cryptographic principles. To get yourself familiar with the topic, see for example [1] or [2] .

• [1] Puncturable Signatures and Applications in Proof-of-Stake Blockchain Protocol [2] Puncturable Signature: A Generic Construction and Instantiations

While (group) messaging systems with strong security guarantees are widely used in practice, these protocols either do not scale efficiently to large groups or provide significantly weaker security guarantees. The candidate construction that is currently considered by the IETF MLS working group is called TreeKEM [1] . First security guarantees for (a variant of) TreeKEM against so-called adaptive adversaries, which may choose their targets adaptively, potentially depending on information they have learned while interacting with the scheme, have been proven in [2] . The goal of this project is to improve on these results using a proof technique that is called rewinding. A strong background in security reductions and probability theory is required for this project.

• [1] The Messaging Layer Security (MLS) Protocol [2] Keep the Dirt: Tainted TreeKEM, Adaptively and Actively Secure Continuous Group Key Agreement

A blind signature scheme is a special type of signature scheme where through interaction, a user can obtain a signature from a signer on a message of their choice without having to reveal said message. Such schemes find applications in electronic voting, electronic payments as well as anonymous credentials. In [1], Boldyreva introduces a blind variant of the pairing-based BLS signature scheme. The security proof is in the random oracle model (ROM) and uses the interactive One-More-CDH assumption. The algebraic group model (AGM)[2] is an abstract model of computation for groups. In the AGM, any adversary is required to explain how they computed group elements in their output from their input. This explanation can be leveraged by a reduction to solve a hard problem and allows for reductions that are not possible in the standard (group) model. Fuchsbauer, Kiltz, and Loss[2] show that in the AGM, plain BLS signatures can have a tight security reduction to the discrete logarithm problem, circumventing an impossibility result for signature schemes with unique signatures. The goal of this thesis is to investigate whether one can improve the security reduction for the blind variant of BLS using the AGM to obtain security based a non-interactive assumption. Familiarity with cryptographic reductions and assumptions (e.g. from the Information Security course) is strongly recommended for this project. Starting date: September 2023.

• [1] Threshold Signatures, Multisignatures and Blind Signatures Based on the Gap-Diffie-Hellman-Group Signature Scheme [2] The Algebraic Group Model and its Applications

When selecting concrete parameters for encryption schemes, one typically aims for „n-bit security” (usually with n = 128), where n-bit security is (informally) defined as “the best attack takes as much time as brute-force trying 2^n keys” or an attack that runs in time t and has advantage ε satisfies t/ε > 2^n [1]. However, the choice of considering t/ε is arbitrary and, for example in group-based schemes there are benefits in considering t^2/ε instead of t/ε (e.g. [2]).

The goal of this project is to consider a 2-dimensional version of security and study how attacks in this setting relate to each other (given an (t,ε)-attack, which (t',ε')-attacks does this imply?), possibly by assuming some properties of the hardness problem (like random self-reduceability), and to study how this notion behaves under reductions (i.e. how reductions affect t and ε and which reductions are preferable in which scenarios).

Cachin and Maurer [1] present a 2-party NIKE with unconditional security in the bounded storage model. In this model, all parties have streaming access to a huge uniformly random string (urs), but have only bounded (much smaller than the size of the urs) storage. However, they only analyze the security in a very weak model (later called “light security”). More realistic models, with multiple (potentially dishonest) users have been proposed in [2,3]. The goal of this thesis is to analyze the CM-NIKE in these more realistic models, ideally the strongest possible model (“adaptive dishonest key registration security”).

The work [3] provides a generic transformation from light to adaptive honest key-registration security (where many, but only honest users are allowed). However, their transformation can not be applied here directly due to the non-negligible correctness error of the CM-NIKE.

Possible extensions: - The CM-NIKE comes with a non-negligible correctness error. Can this be improved or is this unavoidable (for unconditional security in the bounded storage model).
