Sequential traitor tracing
Reihaneh Safavi–Naini, Yejing Wang · IEEE Transactions on Information Theory · 2003
We consider a new type of traitor tracing scheme, called sequential traitor tracing, that protects against rebroadcasting of decrypted content. Sequential traceability (TA) schemes trace all up to c traitors and remove the shortcomings of dynamic tracing schemes. We give two general constructions and show the relationship between c-TA codes and sequential tracing schemes.
