| 摘 要： | 基于椭圆曲线密码算法，提出了一种新的链式验证签名方案，只有经过链式验证授权组中的成员P1、P2、...、Pn-1的一一授权之后，签名验证者Pn才能验证签名的有效性。分析了所给签名方案的安全性和效率。除了具有链式验证签名的一般特性外，还可以方便地增加或删除链式验证授权者，并在链式验证授权者或签名验证者泄漏子秘密时，可以及时地进行维护。

| Abstract: | Based on elliptic curve cryptosystem,a new chain verification signature scheme is proposed,the verifier doesn't verify the validity of the signature until authorized in turn by members of the chain verification authorize group.Authorizers can be added or deleted conveniently.In addition,the proposed scheme can be protected in time when sub-secrets are leaked by verifiers or authorizers.Furthermore,the computing complexity of the proposed scheme is analyzed.It is more secure and efficient than that of discre... |
