Trusted License Distribution System Based on IPSec VPN for MobileDRM

摘要

With the rapid development of mobile applications, DRM systems used for mobile terminals and wireless environmentbecome popular. However, the present DRM schemes are not fit for mobile applications because of the new securityproblems in wireless environment and the limitations of mobile terminals. In this paper, a trusted license distributionsystem based on IPSec VPN and its correlative issues are presented. This system supports DRM clients to build IPSecVPN connection based on trusted authentication with DRM license server, and obtains license through secure tunnel. Implementationand testing indicate that the security and efficiency of the proposed scheme can reach the requirement of themobile DRM.
