Identity-based Traitor Tracing

Abstract : 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 the asymmetric bilinear pairing setting, and that the DDH assumption holds in the group defining the first coordinate of the asymmetric pairing. Our traitor tracing system allows adaptive pirates to be traced. The scheme makes use of a two level identity-based encryption scheme with wildcards (WIBE) based on Waters' identity-based encryption scheme.
