The aim of this work is to find large S-Boxes, typically operating on 8 bits, having both good cryptographic properties and a low implementation cost. Such S-Boxes are suitable bu...
Abstract. This paper sets speed records on well-known Intel chips for the Curve25519 ellipticcurve Diffie-Hellman scheme and the Ed25519 digital signature scheme. In particular, it...
ICEPOLE is a family of authenticated encryptions schemes submitted to the ongoing CAESAR competition and in addition presented at CHES 2014. To justify the use of ICEPOLE, or to po...

COFFE is a hash-based authenticated encryption scheme. In the original paper, it was claimed to have IND-CPA security and also ciphertext integrity even in nonce-misuse scenario. I...
It is a long-standing open problem to prove the existence of (deterministic) hard-core predicates for the Computational Diffie-Hellman (CDH) problem over finite fields, without ...
