| 摘 要： | 基于模合数平方根和因子分解问题的难解性,利用环签名的思想提出一种前向安全可撤消匿名签名方案。该方案使管理员必须和签名接收方合作才能追踪签名者的身份;签名者可以灵活地、主动地选择匿名范围;即使攻击者非法获取了用户当前签名密钥,也无法伪造之前的签名。

| Abstract: | A new forward-secure anonymous signature scheme based on the difficulty of quadratic root modulo composite and factorization problem and the idea of ring signature is proposed in this paper.This scheme has the following advantages:the group manager can only revoke the identity of the signer with the receiver's cooperation;The signer can choose his anonymous scope he wants;Even the attacker obtained the current secret key of some user illegally,he still could not forge the signature of the past time period. |
