在单齿加密-解密算法基础上,提出了一种基于单齿中央加密系统的动态密钥分存方案.研究指出:任意K个系统成员B={B_1,B_2,…,B_k},它们各自选择无规则分布的正整数集合XBi={x_(i1),x_(i2),...,x_(im)}.其中i=1,2,...,k,并公开X_(Bi).利用P〈G, X,X~′〉,任意l个(或更多)Bi能够重构共享密钥.其中k,l∈N,l≤k.研究结果表明,该方案具有良好的保密性和安全性.

The paper put forward a dynamic secret sharing scheme based on the grey centeal public cryptosystem. It pointed out that arbitrary k persons B={B_1,B_2,...,B_k} choose irregular distributed positive integer sets X_(Bi){x_(il),x_(i2),...,x_(im), i=1,2,...,k, and open X_(Bi). Using P〈G, X, X~′〉, l arbitrary (or more)of them can reconstruct the shared key(k,l∈N,l≤k).The results show that the scheme has a good privacy and security.
