Fully Collusion Resistant Traitor Tracing
Abstract
We construct the first fully collusion resistant tracing traitors system with sublinear size ciphertexts and constant size private keys. More precisely, let $N$ be the total number of users. Our system generates ciphertexts of size $O(\sqrt{N})$ and private keys of size $O(1)$. We build our system by first building a simpler primitive called private linear broadcast encryption (PLBE). We then show that any PLBE gives a tracing traitors system with the same parameters. Our system uses bilinear maps in groups of composite order.
