Abstract :
In this paper we introduce a new model "uploading content" in DRM and design a concrete scheme which is based on identity encrypt system and has ability to distinguish the malicious users from the honest with the characteristic of easy DDH in "weak" curves. The improved scheme is against chosen-ciphertext attack.
