The Security Protocol Accelerator and Hardware Security Module, SPAcc-HSM, is a unique security engine that provides reliable protection for sensitive data and transactions and can be shared simultaneously with an application processor that requires lower levels of security.
Digital Right Management (DRM) and content protection standards, such as Digital Transmission Content Protection (DTCP) demand robust security schemes to protect sensitive key information from non-authorized use. The SPAcc-HSM provides specialized access control to key management and application processors and ensures that the security boundaries between the two domains are strictly enforced.
The sharing of cryptographic resources between the two processors allows for significant gate count reduction and smaller memory footprint.
Most security protocols require computationally intensive confidentiality and authentication algorithms to be applied to the data. Content providers require secure key storage to protect valuable data or premium content. The SPAcc-HSM fulfills these requirements by providing a framework that includes a shared programmable sequencer, Secure Key module, Secure DMA engine, and cryptographic/hashing resources.
The CLP-610 also integrates seamlessly in ARM-based SOCs and enables designers to efficiently balance: power, performance, and silicon area.
