Invited Talk - Antoine Joux (CISPA - Germany), winner of the Goedel price - Slide
"MPC in the head for isomorphisms and group action" - Abstract In this talk, we give a tutorial about MPC-in-the-head for signature schemes and illustrate it by designing identification protocols and signature schemes from group actions. We discuss the security of the proposed identification schemes and rely on the Fiat-Shamir transformation to turn them into signatures. We also stress that an essential ingredient for the efficiency of such signature schemes is the use of Puncturable-PRFs.

Room A

Recent Advances in Post-Quantum Cryptography - Abstract Post-quantum cryptography, the study of cryptosystems capable of withstanding both classical and quantum attacks, is a timely area of research, as proven by the standardization effort led by NIST. Recently the focus has been on digital signature schemes, which are the subject of the latest NIST competition.
This workshop will provide an overview of the state of the art in post-quantum cryptography with a focus on cutting-edge methods for designing and implementing post-quantum signature schemes.
