New public key traitor tracing scheme
Zong-yu Song · Computer Engineering and Applications Journal · 2008
In this paper,a public key traitor tracing scheme is proposed.The scheme is based on RSA and the Chinese Remainder Theorem.In this scheme,secrete keys of the receivers are chosen by themselves,the senders have no knowledge of the secret keys of the receivers,that is to say,the scheme is asymmetric.Traitors can not collude in some case.Furthermore,when pirate decoder is found,traitors can be traced by black_box tracing.The tracing algorithm is efficient and deterministic.When traitors are found,the sender can revoke them without involvement of the remaindering receivers.Both senders and receivers are safe.In addition,the receivers can verify whether the message is from correct source.
