Code-based Ring Signature Scheme
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...

ID-based Ring Signature and Proxy Ring Signature Schemes from Bilinear Pairings
In 2001, Rivest et al. rstly introduced the concept of ring signatures. A ring signature is a simpli ed group signature without any manager. It protects the anonymity of a signer....

Solutions to Key Exposure Problem in Ring Signature
In this paper, we suggest solutions to the key exposure problem in ring signature. In particular, we propose the first forward secure ring signature scheme and the first key-insul...

Ring signatures without random oracles
Since the formalization of ring signature by Rivest, Shamir and Tauman in 2001, there are lots of variations appeared in the literature. Almost all of the variations rely on the ra...

An Identity-based Ring Signature Scheme from Bilinear Pairings
At the conference Asiacrypt 2001, Rivest, Shamir and Tauman firstly addressed the concept of ring signature. In this paper we propose an identity-based ring signature scheme from ...
