Bayes Security: A Not So Average Metric
Carmela González Troncoso, Giovanni Cherubin
Security system designers favor worst-case security metrics, such as those derived from differential privacy (DP), due to the strong guarantees they provide. On the downside, these guarantees result in a high penalty on the system's performance. In this pa ...
IEEE2023Thwarting Malicious Adversaries in Homomorphic Encryption Pipelines
Homomorphic Encryption (HE) enables computations to be executed directly on encrypted data. As such, it is an auspicious solution for protecting the confidentiality of sensitive data without impeding its usability. However, HE does not provide any guarante ...
EPFL2023Analysis and Improvements of the Sender Keys Protocol for Group Messaging
Messaging between two parties and in the group setting has enjoyed widespread attention both in practice, and, more recently, from the cryptographic community. One of the main challenges in the area is constructing secure (end-to- end encrypted) and effici ...
2022Six shades lighter: a bit-serial implementation of the AES family
Subhadeep Banik, Muhammed Fatih Balli, Sergio Roldán Lombardía
Recently, cryptographic literature has seen new block cipher designs such as PRESENT, GIFT or SKINNY that aim to be more lightweight than the current standard, i.e., AES. Even though AES family of block ciphers were designed two decades ago, they still rem ...
2021Implications of Position in Cryptography
In our daily lives, people or devices frequently need to learn their location for many reasons as some services depend on the absolute location or the proximity. The outcomes of positioning systems can have critical effects e.g., on military, emergency. Th ...
EPFL2018Affine-malleable Extractors, Spectrum Doubling, and Application to Privacy Amplification
The study of seeded randomness extractors is a major line of research in theoretical computer science. The goal is to construct deterministic algorithms which can take a weak random source x with min-entropy k and a uniformly random seed Y of length d, and ...
