Optimal Traitor Tracing from Pairings
Abstract
We use pairings over elliptic curves to give a collusion-resistant traitor tracing scheme where the sizes of public keys, secret keys, and ciphertexts are independent of the number of users. Prior constructions from pairings had size $\Omega(N^{1/3})$. An additional consequence of our techniques is general result showing that attribute-based encryption for circuits generically implies optimal traitor tracing.
