摘要: 提出了一种基于属性门限签名的动态群组隐私保护公开审计方案,将用户身份信息参数引入用户属性私钥中,有效地防止合谋攻击者通过组合属性密钥来伪造签名.该方案利用基于属性的授权策略,支持用户权限撤销和数据动态操作.分析结果表明,该方案在随机预言模型下具有不可伪造性和抵抗合谋攻击等特点,高效率且安全.

Abstract: A privacy-preserving public auditing scheme for dynamic group shared data based on attribute-based threshold signature was proposed, the identity information parameter was introduced into the attribute keys for preventing collusion attacker who wants to forge signature through the combination of these keys. The proposed scheme supports authority revocation of group user and data dynamic operation with attribute-based authorization strategy. Analysis shows that the proposed scheme with the characteristics of unforgeability and resistance collusion attack based on the random oracle model, and with better efficiency and security.

Key words: attribute-based threshold signature, privacy preserving, public auditing, unforgeability
