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...
Abstract. In 2000, Paulus and Takagi introduced a public key cryptosystem called NICE that exploits the relationship between maximal and non-maximal orders in imaginary quadratic n...

Abstract. In this paper, we present an efficient cryptanalysis of the socalled HM cryptosystem which was published at Asiacrypt’1999, and one perturbed version of HM. Until now, ...
McEliece is one of the oldest known public key cryptosystems, however it was not quite as successful as RSA. One main reason is that it is widely believed that code-based cryptosy...
In 2001, Rivest et al. rstly introduced the concept of ring signatures. A ring signature is a simplied group signature without any manager. It protects the anonymity of a signer....
