摘要 为有效保护数据提供者的合法权益,提出一种基于群的公钥叛逆者追踪方案。依据群合谋的行为特征将合法用户分成不同的群,利用分群思想生成更多合法密钥。在叛逆者检测时将可疑用户缩小到特定群,从而提高检测效率。通过求解大整数分解困难问题和离散对数困难问题证明,该方案完全抗合谋,且具有黑盒追踪性。 To protect the legal interests of copyright owners efficiently, this paper presents a group-based public key pirate tracing scheme. Legal users are divided into groups. By applying group-oriented technique, they can construct more decryption keys. The tracing algorithm is faster as it can first narrow down the traitor to specific group. By combining the discrete log representation problem and large integer factoring problem, this scheme is full collusion resistant, and it has the advantage of black-box tracing.
