Abstract :
An improved collusion-free public-key traitor tracing scheme is proposed and applied in basic DRM model. The proposed scheme modify the leak of the W-H-H-G scheme using the legal user´s secret key that participate in the calculating of decoder, and bind the secret key with the decoder. The new scheme has the ability to resist the collusion attack and can trace the traitor in Black-Box confirmation technique.
