基于中国剩余定理的前向安全群签名方案.

In the group signature,a member can sign the message instead of the group. The verifier can verify the group signature, meanwhile it will not know the identity of the signer. This paper proposed a forward security group signature scheme based on the Chinese remainder theorem. The proposed scheme would dynamically add and delete the group members without modifying the group public key. The scheme had forward security probability, because the attackers couldn' t achieve the keys in other periods even if they corrupted the keys in a certain period. M eanwhile, the proposed scheme achieves these security properties, including anonymity, revocability, anti-forgery, and traceability. [ABSTRACT FROM AUTHOR]
