Abstract
DRM provides a secure solution for the illegal distribution of digital content through communication networks. We propose a Secure and lightweight protocol for mobile DRM based on DRM community cloud (DCC) and banking community cloud (BCC). Non-repudiation property is a very important property that needs to be ensured for DRM. Non-repudiation property in this protocol is achieved using wireless public key infrastructure (WPKI), universal integrated circuit card (UICC) at the client side, DRM community cloud (DCC) at the cloud provider (CP) and banking community cloud (BCC) at the Issuing Bank. BCC and DCC are a Cloud of Secure Elements (CSE). Our proposed protocol achieves end-to-end security from the client to DCC and BCC.
