摘要: 向前安全和可撤消性是群签名体制的重要性质,可以减轻因密钥暴露带来的危害,支持群成员的可撤消性。该文针对具有向前安全和可撤消性群签名方案的一般化实现问题,实现无门限限制的任何大小子集都可形成有效群签名的一般化的拓广,提出一种具有上述性质的一般化的有效群签名方案。

Abstract: Forward security and public revokability are two important properties of a group signature scheme, which can mitigate the damage caused by key exposure and keep secure member revocation. This paper puts forward the realization of the two properties in generalized group signature and designs an efficient and generalized group signature realizing any access structure can sign on behalf of the group.

Key words: generalized group signature, forward-secure, bilinear pairing
