基于NTRU加密系统的叛逆者追踪方案

Traitor Tracing Scheme Based on NTRU

基于NTRU公钥加密系统和中国剩余定理,提出了一种新的叛逆者追踪方案。该方案在无需第三方参与的前提下可抵抗任意数目的共谋攻击,识别所有叛逆者,可进行黑盒子追踪并具有匿名性、非对称性和可扩展性。

A new traitor tracing scheme based on NTRU cryptosystem and Chinese remainder theorem is proposed . The scheme is deterministic and catch all active traitors without any trusted third party regardless of the number of traitors. Even if a coalition of subscribers conspire to create a pirate decoder with a tamper-free decryption key, we have a tracing algorithm to trace them. Finally, the scheme guarantees anonymity,asymmetry and long-liveness.
