Abstract

We propose a secure traitor tracing scheme against adaptive key exposure (TTaKE) which contains the properties of both a traitor tracing scheme and a forward secure public key cryptosystem. It is constructed by using a polynomial with two variables to generate the user secret keys. This scheme enables identification of at least one of traitors. It employs temporary secret keys by updating them. Moreover, we show the way how the building blocks of the TTaKE can be applied to anywhere TV service. Its structure fits current broadcasting systems. The system can improve content broadcasting/distribution services and it enables users to obtain the service at the places where there are not their own STBs/receivers.
