Fully Resilient Traitor Tracing Scheme using Key Update

Eun Sun Yoo, Koutarou Suzuki, and Myung-Hwan Kim

Abstract

This paper proposes fully resilient traitor tracing schemes which have no restriction about the number of traitors. By using the concept of key update, the schemes can make the pirate decoders useless within some time-period, which will be called life-time of the decoder. There is a trade-off between the size of ciphertext and life-time of pirate decoders.
