摘要: 群盲签名是群签名和盲签名的结合体,它兼具群签名和盲签名的各种优越特性,是构造电子现金系统有用的基础工具。在一个不能抵抗联合攻击的高效群签名方案的基础上,通过在私钥中添加随机数,并引入盲化知识签名的思想,构造了一个群盲签名方案。该方案能有效抵抗联合攻击,并能很好地满足群盲签名的各种安全性要求。

Abstract: Group blind signature is a special signature combined group signature and blind signature,which meets all advantages of both group and blind signature.Group blind signature is a useful basic tool in design of E-cash system.The paper proposes a secure and efficient group blind signature based on a group signature which is not coalition-resistant by adding random number to the secret key and introducing blind signature of knowledge.The scheme is coalition-resistant and can meet all security requirements of group blind signature.

Key words: group signature, coalition-resistant, blind signature of knowledge, group blind signature
