Talk Title:
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 at least N^{1/3}.
