Concurrent Signature Based on Verifiable Ring Signature
Jingwei Liu · Computer Engineering and Applications Journal · 2006
In this paper,we first proposed a new concurrent signature based on a verifiable ring signature scheme and constructed a corresponding concurrent signature protocol.At last,we gave the analysis of the security of our scheme.The advantages of concurrent signature scheme is very sufficient to fairness as well as signer-ambiguity,unforgeriability and verifiability.It provides a new way to solve the problem of fair exchange of signatures.
