| 摘 要： | Mu等人提出了一个可撤销用户的付费电视方案，但其方案是私钥方案，并且没有提供多服务的功能，同时也不能抵抗共谋攻击．利用大整数分解困难问题LIFP（Large Integer Factoring Prohlem）和服务参数提出了一个改进的Mu方案．改进方案在将Mu方案变成公钥方案的基础上，增加了提供多种服务、抗共谋攻击、黑盒子追踪等优点，整体性能好于Mu方案．

| Abstract: | Mu et al.proposed a pay-TV scheme with user revocation,but it is a private-key scheme,also it does not provide multiple-service capability and meantime can not resist collusion attack.An improved scheme is proposed by using LIFP(Large Integer Factoring Problem) and service parameter.On the basis of transforming Mu's scheme into public-key traitor tracing scheme,the advantages such as providing multiple-service,collusion-resistance and black-box tracing are added.Furthermore,the whole capabilities of the improved scheme are better than that of Mu's. |
