We give a short constant-size group signature scheme, which we prove fully secure under reasonable assumptions in bilinear groups, in the standard model. We achieve this result by ...

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...
