Public-Key Based Lightweight Swarm Authentication

• Simon Cogliani, Feng Bao, +5 authors Guilin Wang
• IACR Cryptology ePrint Archive
• 2016

We describe a lightweight algorithm performing whole-network authentication in a distributed way. This protocol is more efficient than one-to-one node authentication: it results in less… (More)

Thrifty Zero-Knowledge - When Linear Programming Meets Cryptography

• Simon Cogliani, Houda Ferradi, Rémi Géraud, David Naccache
• ISPEC
• 2016

We introduce “thrifty” zero-knowledge protocols, or TZK. These protocols are constructed by introducing a bias in the challenge send by the prover. This bias is chosen so as to maximize the security… (More)

A Fiat-Shamir Implementation Note

• Simon Cogliani, Rémi Géraud, David Naccache
• IACR Cryptology ePrint Archive
• 2016

In the Micali-Shamir paper [7] improving the efficiency of the original Fiat-Shamir protocol [5,6,9], the authors state that “(. . .) not all of the vi’s will be quadratic residues mod n. We overcome… (More)
