论文给出了一种新的基于可验证环签名的同时生效签名算法和相应的同时生效签名协议,并对其安全性进行了分析。签名方案除了满足签名者模糊性、不可伪造性、可鉴别性外。还很好地满足了公平性.为解决签名交换的公平性问题提供了一种新的方法。
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.h provides a new way to solve the problem of fair exchange of signatures.
