A Cryptosystem Based on the Composition of Reversible Cellular Automata
We present conditions which guarantee that a composition of marker cellular automata has the same neighbourhood as each of the individual components. We show that, under certain te...

Identity-Based Traitor Tracing
We present the first identity-based traitor tracing scheme. The scheme is shown to be secure in the standard model, assuming the bilinear decision Diffie-Hellman (DBDH) is hard in...
