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:

A new Chain Verification signature scheme was proposed based on Elliptic Curve Cryptosystem, Which enables verifier Pn to verify the validity of the signature only after being authorized by members P1、P2、...、Pn-1 of the chain verification group. The security and effectiveness of the proposed scheme was analyzed. The proposed scheme not only possesses the properties of Chain Verification Signature, but also contains the following properties: chain authorized verifiers can be easily added or deleted and the sub-secrets can be protected in time.

Key words: Chain Verification Signature, Elliptic Curve, multisignature
