Abstract
A secure execution environment for execution of sensitive code and data including a secure asset management unit (SAMU) is described. The SAMU provides a secure execution environment to run sensitive code, for example, code associated with copy protection schemes established for content consumption. The SAMU architecture allows for hardware-based secure boot and memory protection and provides on-demand code execution for code provided by a host processor. The SAMU may boot from an encrypted and signed kernel code, and execute encrypted, signed code. The hardware-based security configuration facilitates preventing vertical or horizontal privilege violations.
