Hawk: Module LIP Makes Lattice Signatures Fast, Compact and Simple
Autor: Léo Ducas, Eamonn W. Postlethwaite, Ludo N. Pulles, Wessel van Woerden
Publikováno v: Advances in Cryptology – ASIACRYPT 2022 ISBN: 9783031229718
We propose the signature scheme Hawk, a concrete instantiation of proposals to use the Lattice Isomorphism Problem (LIP) as a foundation for cryptography that focuses on simplicity. This simplicity stems from LIP, which allows the use of lattices suc

A concrete treatment of efficient continuous group key agreement via multi-recipient PKEs
Autor: Bas Westerbaan, Shuichi Katsumata, Thomas Prest, Eamonn W. Postlethwaite, Keitaro Hashimoto
Publikováno v: CCS
Continuous group key agreements (CGKAs) are a class of protocols that can provide strong security guarantees to secure group messaging protocols such as Signal and MLS. Protection against device compromise is provided by commit messages: at a regular

As lattice-based key encapsulation, digital signature, and fully homomorphic encryption schemes near standardisation, ever more focus is being directed to the precise estimation of the security of these schemes. The primal attack reduces key recovery

Quantum variants of lattice sieve algorithms are routinely used to assess the security of lattice based cryptographic constructions. In this work we provide a heuristic, non-asymptotic, analysis of the cost of several algorithms for near neighbour se

Quantum Algorithms for the Approximate k-List Problem and Their Application to Lattice Sieving

Publikováno v: Lecture Notes in Computer Science ISBN: 9783030345778
ASIACRYPT (1)
The Shortest Vector Problem (SVP) is one of the mathematical foundations of lattice based cryptography. Lattice sieve algorithms are amongst the foremost methods of solving SVP. The asymptotically fastest known classical and quantum sieves solve SVP
