But BT does not enforce the access control process, so a lot of unauthorized files are freely shared. In this paper, we proposed a digital rights management (DRM) system for BT environment to solve the serious piracy issue by using lightweight encryption methods in order to he adopted by small mobile devices in wireless environment.展开更多
