Traitor Tracing Scheme Based on NTRU
基于NTRU加密系统的叛逆者追踪方案*

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.
