Paper: On the Security of Fully Collusion Resistant Traitor Tracing Schemes

Deng URL: http://eprint.iacr.org/2008/450 Search ePrint Search Google This paper investigates the security of FTT (fully collusion resistant traitor tracing) schemes in terms of DOT (Denial Of Tracing) and framing. With DOT attack, a decoder is able to detect tracing activity, and then prolongs the tracing process such that the tracer is unable to complete tracing job in a realistic time duration and hence has to abort his effort. On the other hand, by merely embedding several bytes of non-volatile memory in the decoder, we demonstrate, for the FTT schemes, how the decoder can frame innocent users at will. Furthermore, we propose a countermeasure on the framing attack.
