摘要
首先对数字证书认证机制进行安全性分析,并结合RSA签名算法的自身特点和先验式秘密共享机制的发展现状提出了一种基于多代理的分步签名方案。该方案一方面解决了离线签名的效率问题,另一方面解决了传统签名的安全问题。最后结合分步签名的实现论证了方案的可行性。
The authors first analyze the security of digital certificate identification mechanism, then bring forward a scheme of signature step by step based on multi - agent based on the feature of RAS signature algorithm and the present status of prior secret - share mechanism, which solves both the efficiency problem of off- line signature and the security problem of traditional signature. The feasibility of the scheme is demonstrated by the realization of the signature step by step.
