摘要: 提出一种基于RSA的公钥叛逆追踪方案。在该方案中,供应商无法诬陷无辜用户,而且该方案支持黑盒子追踪。追踪算法是确定型的,其实现不受共谋用户数量的限制,用户可以随时加入或退出该系统。当供应商发现非法用户时,不要求合法用户作任何改变就能很方便地取消非法用户。

关键词: 黑盒子追踪, 叛逆追踪, 分层服务

Abstract: This paper proposes a public key traitor tracing scheme based on RSA. In this scheme, broadcaster can not frame innocent users and the traitors can be traced by black-box tracing. The tracing algorithm is deterministic and it works without the limitation of the number of traitors. The scheme deals with stateless receivers. When traitors are found, the broadcaster can revoke them without involvement of the remaindering receirvers.

Key words: black-box tracing, traitor tracing, service based on role
