Abstract
A secure element operating in conjunction with a secure partition of a system-on-a-chip (SoC) having set top box (STB) functionality allows for digital rights management (DRM) key handling in a mobile platform. The secure element can include a secure processing system (SPS) to be implemented as a hard macro, thereby isolating the SPS from a peripheral processing system (PPS). The secure element and the secure partition of the SoC may be operatively connected by a secure cryptographic channel.
Claims19
An apparatus, comprising:
- a semiconductor chip having a secure partition for processing a media signal;
- and
- a secure element for performing key handling of at least one digital rights management (DRM) scheme, wherein the secure element is operatively connected to the semiconductor chip via a secure cryptographic channel.
An apparatus, comprising
- a secure element for handling digital rights management (DRM) private keys;
- a host processor for controlling the embedded secure element;
- and
- a key router for receiving encrypted DRM private keys from the secure element, wherein the host processor and the key router are co-located on a system-on-a-chip (SoC), and the secure element is connected to the key router via a secure cryptographic channel.
1 more element
A system, comprising:
- a host device comprising a host processor;
- a secure element comprising:
- a secure processing sub-system implemented as a hard macro for processing media content;
- and
- a peripheral processing sub-system for relaying communications to and from the secure processing sub-system and the host device, wherein the secure processing sub-system is hardware isolated from the peripheral processing sub-system;
- and
- a system-on-chip (SoC) for implementing set top box functionality within the host device.
