给出一个新的基于双线性对的代理环签名方案,与A-S方案相比,该方案更有效,因为在签名生成时不需要双线性对运算。该方案是代理签名和环签名的结合,由于它具有代理签名和环签名两者的优点,因此在代理签名者需要代表原始签名者签名,同时又需要提供匿名性时是非常有用的。
A new proxy ring signature scheme based on bilinear pairings is proposed. As compared with A-S scheme, this scheme is more efficient because there is no computational cost of bilinear pairings at signature generation. The scheme is the combination of proxy signature and ring signature scheme. It has advantages of proxy signature and ring signature. It is very useful when proxy signers need to sign messages on behalf of the original entity while providing anonymity.
