摘　　要：探讨了一个基于中国剩余定理的群签名问题中的群成员秘钥生成分配问题,利用RSA系统对群成员的私钥进行二次加密,使得群成员能够参与到群成员私钥的生成过程中.基于大数分解的困难性,使得该方案中群成员私钥更具由安全性而且能够更有效避免群中心的陷害攻击.This paper discussed the generation and distribution of group members’ secret keys in a group signature problem based on Chinese remainder theorem. RSA system was used to encrypt the private keys of group members twice, so that group members can participate in the generation process of group members’ private keys. Based on the difficulty of large number decomposition, this makes the private key of the group member more secure, and can more effectively avoid the framing attack of the group center.
