Title:
Optimal Traitor Tracing from Pairings
Authors: Mark Zhandry
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}). Our construction is non-black box.
