New Proxy Ring Signature Scheme Based on Bilinear Pairings
一种新的基于双线性对的代理环签名方案*

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.
