Most public key cryptosystems have been constructed based on abelian groups up to now. We propose a new public key cryptosystem built on finite non abelian groups in this paper. I...

Abstract. This paper introduces a cryptographic paradigm called selfescrowed encryption, a concept initiated by kleptography. In simple words, a self-escrowed public-key cryptosyst...
Abstract. Physical attacks on cryptographic implementations and devices have become crucial. In this context a recent line of research on a new class of side-channel attacks, calle...

Signcryption, first proposed by Zheng [4,5], is a cryptographic primitive which combines both the functions of digital signature and public key encryption in a logical single step,...
Abstract. The Naccache-Stern (ns) knapsack cryptosystem is an original yet little-known public-key encryption scheme. In this scheme, the ciphertext is obtained by multiplying publ...
