Abstract

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

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。
