Abstract
The present invention relates to a method for traitor tracing. One embodiment of a method for determining at least one traced private key used by a decoder to decrypt an encrypted message includes defining an input ciphertext, the input ciphertext being associated with a tracing private key and having a sublinear size, calling the decoder on the input ciphertext, and associating the tracing private key with a set of traced private keys if the decoder is able to correctly decrypt the encrypted message in accordance with the input ciphertext, the set of traced private keys including at least one private key.
