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....
Current techniques for transforming unforgeable signature schemes (the forged message has never been signed) to strongly unforgeable ones (the forged message could have been signed...
In this paper, we propose a new signature scheme that is existentially unforgeable under a chosen message attack without random oracle. The security of our scheme depends on a new ...
It has always been a critical issue to find efficient methods for fast revocation of a user's identity in identity (ID)based cryptosystems. Unfortunately, none of the previou...
: In Crypto 1997, Goldreich, Goldwasser and Halevi (GGH) proposed a lattice analogue of McEliece public key cryptosystem, in which security is related to the hardness of approximat...

Aggregate signatures are a useful primitive which allows to aggregate into a single and constant-length signature many signatures on different messages computed by different users...
An aggregate signature scheme is a digital signature scheme where anyone given n signatures on n messages from n users can aggregate all these signatures into a single short signa...
In this paper we propose a new designated verifier signature scheme based on the threshold signature scheme presented [8] by Ghodosi and Pieprzyk. The advantages of the new scheme ...
Abstract. Known compact e-cash schemes are constructed from signature schemes with efficient protocols and verifiable random functions. In this paper, we introduce a different ap...
