A New Traitor Tracing
Summary :
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. The conventional schemes have some problems; one of them is that there exists an upper bound on the sizes of keys to certify the security of the scheme against a collusion attack by many traitors, and so that the size of the header increases according to the increase of the bound. We shall propose a new traitor tracing scheme where the header size is independent of the number of traitors.
