PROXY GROUP SIGNATURE: A NEW ANONYMOUS PROXY SIGNATURE SCHEME

摘要：

In the proxy signature scheme, the capability of anonymous proxy is requested for protecting the proxy signers privacy. This paper introduces a concept and model of proxy group signature and constructs a proxy group signature scheme based on bilinear pairings. The proposed scheme has the properties of hiding the identity of the signer in the signature and the signers identity can be revealed by a special manager when the dispute arises, so it is a new anonymous proxy signature scheme. The analysis of security shows that the scheme satisfies the security requirements such as verifiability, strong unforgeability, strong non-repudiation, proxy privacy and privacy revocation.
