The SAMU provides a secure execution environment to run multiple instances of separate program code or data 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 multiple instances of separate program code or data 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 the prevention of vertical or horizontal privilege violations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for including architecture for protecting multi-user sensitive code and data","description":"A secure execution environment for execution of sensitive code and data including a secure asset management unit (SAMU) is described.
