摘要
分析群体用户对信息安全的特殊需求,提出了一种面向群体的数字签名,签名方案基于公开密钥RSA算法,采用多项式对密钥进行分割,实现了双方群体不可否认的数字签名方案。
In this paper,the special requireme nts of group user are analyzed.A kind of group digi-tal signature is proposed,this scheme is base on public -key RSA algorith m and the key is shared by poly-nomial,A scheme for digital signatu re of group in both side being undenia ble is realized.
