Secure File Sharing Scheme for Mobile Devices

An ideal file sharing method is all mobile users can directly share their files one-to-one in the mobile peer-to-peer (MP2P) environment. However, some copyright multimedia files usually are shared and downloaded extensively through P2P technology, so P2P technology has a bad reputation by these illegal distribution behaviors. Hence, how to effectively control unauthorized digital content distribution is a security issue that needed to be solved in P2P environment. Accordingly, this paper proposes a scheme that users can access files via mobile devices through wireless communication. And we can reduce the cost and share files quickly by the concept of P2P. In addition, the paper involves Digital Rights Management to protect digital contents from illegal distribution and reproduced. Furthermore, a user can efficiently and legally transfer his license from one of his devices to one another in our scheme.
