In this paper we study the design of efficient trace- revoke schemes for content protection. In state-of-art, broadcast encryption and traitor tracing are viewed as two orthogonal problems.

Problem 2: Consistency. In traitor tracing, the functionality of the various user keys is different. This is inherent, for similar reasons to the case of watermarking as explained by Barak et al. : if each user key had identical functionality, then a traitor could apply indistinguishability obfuscation (iO) to their key. The guarantees of iO would then imply the …

The idea behind traitor tracing is to deter piracy by making it so that the act of leaking a secret key reveals the identity of the traitor. 1.2 Di culties A na ve approach might be as follows: generate a pair (pk;sk), and distribute to user i the secret key (sk;i). The problem, of course, is that only sk is needed to decrypt, not i, so a user could

The usage of traitor tracing schemes discourages users from helping pirates and especially from submitting their keys to be used in pirate decoders. In particular, if the process of a user obtaining a personal key requires some sort of registration and physicalidentificationthenitshouldbehardforpiratestoobtain a large number of personal keys.
Traitor Tracing with Optimal Transmission Rate
https://cs.nyu.edu/~nicolosi/papers/ott.pdf
as pointed out by kiayias and yung in [ky02b], an important problem in designing practical traitor tracing schemes is to ensure a low transmission rate (defined as the asymptotic ratio of the size of ciphertexts over the size of plaintexts), while at the same time minimize the secret-and the public-storage rates (similarly defined as the asymptotic …

In addition, the concepts and techniques of traitor tracing have had broader impacts in cryptography and privacy. Most notably Dwork et al. [DNR+09] showed that the existence of traitor tracing schemes leads to certain impossibility results in the area of di erential privacy [DMNS06]. Brie y, they consider the problem
