On the Security of Fully Collusion Resistant Traitor Tracing Schemes
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
