分析了现有网上签名方案,提出一种基于双重二方共享机制的容侵网上签名方案,即在应用服务器(AS)与密钥服务器(SS)以双方公钥密码算法共享密钥的基础上,引入了密钥服务器与密钥共享服务器(SSS)共享密钥的机制。方案可以使在应用服务器与密钥服务器相互认证的同时,实现密钥服务器与密钥共享服务器之间的相互认证,从而进一步加强了系统的容侵性能。
This paper analyzes the existing online signature scheme and proposes a capacity-based on-line signature scheme based on the double two-share scheme. That is, based on the shared key between the AS and the key server (SS) , Introduced a mechanism for the key server to share the key with the key share server (SSS). The scheme enables mutual authentication between the key server and the key sharing server while the application server and the key server mutually authenticate each other, thereby further enhancing the capacity of the system.
