Among traitor tracing schemes, our interest is in a black-box tracing scheme in the public-key setting. In black-box tracing, a tracer does not break open the pirate decoder but uses it as a black box. Brie y, the tracer chooses a set of suspects and tests whether traitors are included in it only by observing the

Black-box tracing Traitors can be identified from the pirate decoder used as a black box The tracer chooses a set of suspects and inputs the header which can (or cannot) be decrypted by the selected suspects A scheme in which header size is linear in the total number of users is trivial Pirate decoder Input (header) Output

In this paper, we propose a public-key traitor tracing scheme that has optimal transmission rate. In other words, our scheme enables everyone to transmit the encrypted digital contents almost without any redundancy. As for tracing, our scheme supports black-box tracing, i.e., identifying colluders without opening the pirate decoder.

Beside the most important open problem of obtimizing the black-box tracing, Boneh-Franklin also left an open problem concerning non-black-box tracing, by mentioning: “it seems reasonable to believe that there exists an efficient public key traitor tracing scheme that is completely collusion resistant.

Two desirable properties of a traitor tracing scheme are (i) Public-key traitor tracing, where any third party is able to send secure messages to the set of subscribers (in- creasing the functionality and scale of the service); and (ii) Black-box traitor tracing, which
