Secure DRM scheme for future mobile networks based on trusted mobile platform

摘要

With the emergence of wide bandwidth wireless networks, mobile Internet is set to provide a significant channel for multimedia content distribution. The need for mobile digital right management (DRM) solution is thus intensified in order to safeguard mobile media content. The open mobile alliance (OMA) has been set to define open DRM technologic specifications to protect copyrighted content against piracy, unauthorized use and distribution over mobile networks. However, we argue that there still are some potential security flaws in its recent version 2 specifications. A secure DRM scheme based on trusted mobile platform (TMP) is proposed in this paper to enhance the security of OMA DRM specification v2 and provide interoperability and compatibility between trusted computing (TC) and OMA DRM. According to our analysis thereafter the TMP in conjunction with OMA DRM v2 may offer a considerably more robust DRM system for future mobile networks.
