摘　　要：提出了基于移动设备的匿名可追踪的版权管理协议。首先,它使用不断变换的临时身份来代替用户的真实身份,使其他人不可能跟踪到用户,它关注用户动态,具有匿名性;其次,使用一次口令申请一个水印的方法来抵抗假冒攻击;再次,采用单向哈希函数的认证方法对用户身份、数字内容进行验证;协议中的一些计算由可信中心完成,以减少移动用户的计算量,提高效率。另外在数字产品中嵌入版权水印和指纹水印,当发现非法副本时,它可以对叛逆者进行追踪,具有可追踪性。分析表明,该协议是安全有效的。Anonymous and traceable copyright protection protocol based on mobile devices was put forward in this paper.Firstly,others can not track the user by using the changing identity to replace user＇s true identity in the protocol.The anonymous nature exists in the protocol.Secondly,the protocol uses the method that one password only applies one fingerprint watermark so that the protocol resists the fake attack.Thirdly,while using one-way hash function to verify the identity of participators and the digital content,the protocol transfers the calculating works to the trusted center RA with enough computing ability from mobile users.The two behaviors reduce the mobile＇s calculating works,and improve efficiency.In addition,the copyright watermark and fingerprint watermark embedded in the digital product are used to trace the traitor when finding one or more illegal copies of the digital product.So the protocol has the ability of traitor tracing.The analysis indicates that the protocol is secure and practical.
