Embedded DRM technology supports Linux

jacky002

Discretix has demonstrated its digital rights management (DRM) technology running on a Trolltech Qtopia-based Linux phone. The Discretix Multi-Scheme DRM Client can be used to establish a trusted environment for distributing premium content to devices with or without embedded cryptographic hardware co-processors, the company said.

The Discretix Multi-Scheme DRM Client was demonstrated at the Mobile World Congress in Barcelona this week. It was shown running as a pre-integrated component on a phone that was also running Trolltech's Qtopia application and middleware stack for Linux phones.

Discretix says its content security technology reduces OEM time to market by ensuring pre-tested DRM protection for premium content. It supports multiple business models, including purchase, rental, and subscription, depending on the application deployed.

The Multi-Scheme DRM Client supports a wide range of operating systems, including Linux, and is said to present a unified application programming interface (API) to the application layer, regardless of the underlying DRM scheme. The client supports hardware platforms including Texas Instruments (TI) OMAP, TI OMAP-VOX, Infineon MPEH/MPEU, Renesas SH-Mobile, and NXP Nexperia. It can also integrate with hardware-based security technologies such as Texas Instruments' M-Shield or its own Discretix CryptoCell. The client can easily support new hardware platforms thanks to its thin software glue layer called the Discretix Virtual Operating System, says the company.

The integration with embedded Linux gives device manufacturers and consumers alike the world-class protection they're looking for."
