OMA evolving the DRM solution, Dec. 2003
DRM solution is evolving with the mobile industry. The higher bandwidth provided by 2,5G and 3G cellular networks allow larger content files to be transmitted over the air. Proliferation of wireless Internet "hotspots" makes Internet access easily available to consumers. Smart mobile devices with removable media and larger color screens support downloading and streaming rich media content. Content and service providers are eager to release rich audio/video content and applications into the mobile marketplace. All these factors contribute to the requirements of continuously enhanced OMA DRM solution. Greater security and trust management is required to protect the high value content. There's a need to ensure that the target device can be trusted to keep the content and secrets safe. Greater security is also needed in order to prevent content from leaking out during the acts of downloading and other distribution. The Open Mobile Alliance is meeting these market needs by upgrading the existing OMA DRM Enabler Release with enhanced features. The next version of OMA DRM will add enhanced security by encrypting the rights object and the content encryption key by using the device's public key to bind them to the target device. Integrity protection for both content and the rights object will be added to reduce the risk of tampering. In addition to these enhanced security features, additional trust elements will be introduced. Mutual authentication between the device and the rights issuer, i.e. the content retailer, will add trust to the downloading or messaging scenario. The rights issuer will be able to accurately identify the device in order to determine the revocation status of the transaction. [\b],
