摘要
基于RSA提出了面向组(n,n)的数字多签名方案,组内由n个用户组成,任何组签名由n个成员互相生成,组签名的大小等于单个签名的大小,组成员对信息的签名不存在盲签名,外界用户可以认证组签名,签名认证过程简单,只需要一个组对外的公开密钥,组对签名消息负责。方案中组的公开密钥由所有成员的密钥决定,组内不需要设立收集者,通信耗费少。
The paper proposes a group (n,n) oriented digital multisignature based on RSA. The group signature is created by all members in the group, but the size of the group signature is equal to that of individual signature. The group signature can be verified by any outsider through one group public key. The members can figure out m before signing, so the signing processes are not blind. It is not necessary to have a collector in the group, so the cost of the communication is small.
