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 usrs from the honest with the characteristic of easy DDH in "weak" curves. The improved shceme is against chosenciphertext attack.
