System and Method for Processor-Based Security

Web Published:

Princeton Docket #09-2533-1


A system and method for processor-based security is provided, for on-chip security and trusted computing services for software applications. Secure execution environments (compartments or enclaves) are provided for executing trusted software by a secure processor and a trusted hypervisor. Secure memory and secure storage are provided for the hypervisor and for the trusted software modules. Secure module interactions are provided, as well as the generation of a power-on key which can be used to protect memory in the event of a re-boot event. Lightweight, run-time attestation reports are generated which include selected information about software modules executed by the processors, for use in determining whether the processor is trusted to provide secure services.
