摘要
RSA是应用最广泛的公钥密码体制之一,本文提出基于RSA的群盲签名方案.该方案可以安全地增加或撤消群成员;可以高效地实现群成员的增加或撤消群;也可适合大的群体使用;具备了基于大数分解困难性的安全性.
RSA is one of the most popular public key cryptogram algirithms, a new group blind signature scheme completely based on RSA is proposed. The new scheme safely add or delete members while keeping the secret keys of the other available members unchanged, it efficiently realize the add or delete process, it fits big groups and its security relies on the difficulty to disassemble a big number.
