Abstract: An improved traitor tracing scheme based on modified RSA is proposed, which solves the existing schemes problem
of fixed session key by introducing a random number with its security improved. Meanwhile, the new traitor tracing scheme is
reconstructed by modified RSA algorithms and its efficiency is also improved. The proposed scheme allows efficient
deterministric traitor tracing to recover all traitors.

Key words: traitor tracing, modified RSA algorithm, broadcast encryption
