Mobile Digital Right Management with enhanced security using limited-use session keys

Digital contents have been increasing rapidly in which they can contribute to business-to-customer productivity growth. A number of Mobile Digital Rights Management (MDRM) protocols have been proposed. The aim of MDRM is to distribute digital contents to consumers in a controlled manner that can protect the copyright of digital contents. Some protocols do not provide necessary security properties; hence, they may not be suitable for mobile network. This paper introduces MDRM protocols for distribution of digital contents. The proposed protocols deploy limited-use offline session key generation and distribution technique to enhance security and importantly make it lightweight and more secure. Moreover, the proposed protocols are suitable for current mobile infrastructure and thus maintain ease of use.
