An Efficient Traitor Tracing Scheme Based on M Sequence
Cai Qin-jun · Communications technology · 2008
A traitor tracing scheme based on M sequence is proposed. In this scheme, the tracer can trace at least one of the users who make the pirate (called traitors) with black-box method when the pirate is found. The main character of this scheme is that the number of tracing is linear with the number of users. So the tracing algorithm is very efficient. In addition, there is no restriction on the number of colluders.
