CrySP carries out research in a wide variety of topics. Some examples are:
(Distributed) cryptographic protocols. Designing interactive protocols to enable secure communication, such as key agreement protocols, key distribution schemes, secret sharing schemes, identification schemes, broadcast encryption and oblivious transfer (D. Stinson).
Efficient cryptographic algorithms and their implementation. Designing and analyzing cryptographic primitives such as block and stream ciphers, public-key encryption schemes, signature schemes, message authentication codes, key establishment protocols, and pairing-based cryptography (D. Stinson).
Cryptographic hash functions. Analyzing the security of iterated design techniques and the random oracle model and constructing families of universal hash functions (D. Stinson).
- Privacy-preserving communications networks.
Creating privacy-preserving communications networks with better
security, privacy, efficiency, and scalability properties than
- Off-the-Record Messaging.
Improving the user interface, robustness, and group communication abilities of
Off-the-Record Messaging, or
- Censorship Resistance.
Designing, developing, and deploying censorship resistance technologies,
examining the motivations of the censor and the resister, and analyzing
the game-theoretic aspects of their interactions.
- Private Information Retrieval.
Creating Private Information Retrieval (PIR) protocols that are
computationally and communicationally efficient, while also providing
for Byzantine robustness.
- Efficient Zero-Knowledge Proofs.
Developing batch techniques for Zero-Knowledge Proofs (ZKPs)
that make a larger variety of complex ZKPs
more efficient; developing a software library that can be
easily used by programmers without expertise in ZKPs to prove
and verify simple, complex, and batched statements.
Security and privacy for smartphone users. Developing security and privacy technologies that allow smartphone users to use mobile apps in a secure and privacy-protecting way. (U. Hengartner).
Location privacy. Developing privacy-preserving technologies for
users of location-based services. (U. Hengartner).
Genomic Privacy. Developing privacy-preserving technologies to protect the storage and processing of genomic data. (U. Hengartner).
Privacy for (mobile) social networking. Designing privacy-preserving technologies for users of (mobile) online social networking sites. (U. Hengartner).
Cryptographic and online voting. Designing and analyzing voting protocols with high usability and voter-verifiable correctness (U. Hengartner).
Response and recovery strategies. Evaluating and designing effective incident response strategies to ensure business continuity (I. McKillop).
Security assessment and audit. Applying system vulnerability and risk assessment techniques with a particular focus on the financial services and health sectors. (I. McKillop).
Computation over encrypted data and programs. Developing theoretical
and practical foundations for secure computation over encrypted data and
programs (functional encryption, homomorphic encryption, multi-party
computation, multilinear maps and program obfuscation) (S. Gorbunov).
Cryptocurrencies. Developing and building new
cryptocurrencies (S. Gorbunov).
