Abstract
This chapter gives an overview of the Open Mobile AllianceTM Digital Rights Management (OMA DRM) standard, which allows for the secure distribution and usage of protected digital content. Additionally, the DRM Profile of the OMA Mobile Broadcast Services standard, which is an extension of the OMA DRM standard to support mobile broadcast applications, is discussed. This chapter also introduces the associated OMA Secure Removable Media (OMA SRM) and OMA Secure Content Exchange (OMA SCE) standards, which increase the portability of DRM-protected content and offer a better user experience. The aim of this chapter is to give the reader insight in the above mentioned standards, their technical background, and possible usage scenarios.
