Fully collusion-resistant traitor tracing scheme with shorter ciphertexts
2010
Designs, Codes and Cryptography
A traitor tracing scheme allows a content distributor to detect at least one of the traitors whose secret key is used to create a pirate decoder. In building efficient traitor tracing schemes, reducing ciphertext size is a significant factor since the traitor tracing scheme must handle a larger number of users. In this paper, we present a fully collusion-resistant traitor tracing scheme where the ciphertext size is 2.8 times shorter and encryption time is 2.6 times faster, compared to the best
