Hence, our system provides a simple and efficient solution to the "traitor tracing problem". A minor modification to the scheme enables it to resist an adaptive chosen ciphertext attack. ...

An important open problem in the area of Traitor Tracing is designing a scheme with constant expansion of the size of keys (users' keys and the encryption key) and of the size of ciphertexts with respect ...
Then, we observe the simple yet crucial relation between (public-key) copyrighted encryption and (public-key) traitor tracing, which we exploit by introducing a generic design paradigm for designing constant ...
The Lemma provides a construction methodology for public-key traitor tracing schemes: given an n-key,c-copyrighted public-key encryption scheme the corresponding public-key traitor tracing scheme is the ...

We propose the first constant ciphertext rate scheme which copes with such pirate decoders. Our scheme moreover supports black-box public traceability. c Springer-Verlag 2006. ...
These decoders can keep states between decryptions to detect whether they are being traced and are then able to take some counter-actions against the tracing process, such as "shutting down" or erasing ...
We then introduce an efficient generalization of the basic scheme to obtain an efficient general scheme. Although our basic scheme is significantly less efficient than Phan et al.' ...
