On the Theory and Practice of Modern Secure Messaging
Billions of people now have conversations daily over the Internet. A large portion of this communication takes place via secure messaging protocols that offer "end-to-end encryption'" guarantees and resilience to compromise like the widely-used Double Ratc ...
EPFL2024Cryptographic Administration for Secure Group Messaging
Serge Vaudenay, Daniel Patrick Collins
Many real-world group messaging systems delegate group administration to the application level, failing to provide formal guarantees related to group membership. Taking a cryptographic approach to group administration can prevent both implementation and pr ...
2023On Quantum Secure Compressing Pseudorandom Functions
In this paper we characterize all 2n-bit-to-n-bit Pseudorandom Functions (PRFs) constructed with the minimum number of calls to n-bit-to-n-bit PRFs and arbitrary number of linear functions. First, we show that all two-round constructions are either classic ...
2023A review of the security vulnerabilities and countermeasures in the Internet of Things solutions: A bright future for the Blockchain
Jan Van Herle, Hossein Pourrahmani
The current advances in the Internet of Things (IoT) and the solutions being offered by this technology have accounted IoT among the top ten technologies that will transform the global economy by 2030. IoT is a state-of-the-art paradigm that has developed ...
2023Thwarting 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 ...
EPFL2023Optimal Symmetric Ratcheting for Secure Communication
Serge Vaudenay, Andrea Felice Caforio, Daniel Patrick Collins, Hailun Yan
To mitigate state exposure threats to long-lived instant messaging sessions, ratcheting was introduced, which is used in practice in protocols like Signal. However, existing ratcheting protocols generally come with a high cost. Recently, Caforio et al. pro ...
