    A traitor tracing scheme is a broadcast encryption scheme in which a provider can trace malicious authorized users who illegally gave their personal keys to unauthorized users.

    A new model for traitor tracing, which we call the shared randomness model (SRM), where encryption, decryption, and the decoder have access to a large source of randomness that is not included in the communication costs. While we define the model as a stepping stone toward a full tracing algorithm in the plain model, our shared randomness …

    Mitsunari et al [15] presented a new traitor tracing scheme which uses Weil pairing in elliptic curves. To the best of our knowledge this is the first scheme that uses bilinear map. The claimed advantage of the scheme is that the ciphertext size is independent of the number of traitors.

    In this work, we show that this intuition is false by building a traitor tracing scheme from pairings with $O(\sqrt[3]{N})$-sized parameters. We obtain our scheme by developing a number of new traitor tracing techniques offering various trade-offs that were not possible before, giving the first significant parameter improvements in pairings-based traitor tracing in over a decade.

    New Techniques for Traitor Tracing: Size $N^{1/3}$ and More from Pairings. Mark Zhandry. Abstract: The best existing pairing-based traitor tracing schemes have $O(\sqrt{N})$-sized parameters, which has stood since 2006. This intuitively seems to be consistent with the fact that pairings allow for degree-2 computations, yielding a quadratic compression.

Traitor tracing - Wikipedia

    https://en.wikipedia.org/wiki/Traitor_tracing
    Traitor tracing key assignment schemes can be translated into such digital watermarking schemes. Traitor tracing is a copyright infringement detection system which works by tracing the source of leaked files rather than by direct copy protection. The method is that the distributor adds a unique salt to each copy given out. When a copy of it is leaked to the public, the …

Traitor Tracing with Optimal Transmission Rate

    https://cs.nyu.edu/~nicolosi/papers/ott.pdf
    As originally observed in [GSY99], traitor tracing scheme are most useful when combined with a re- vocation scheme; such trace-and-revoke approach consists in first uncovering the compromised decryption keys and then revoking their decryption capabilities, thus rendering the corresponding pirate decoder useless [NP00,TT01,NNL01,DF02,DF03,KHL03,DFKY05,BW06].
