1 Security Goals of AM26x Devices

  • Modules and platform protection -
    • Protect modules (hardware and software) and defend platform from takeover and unauthorized modifications.
    • Protect critical assets and resources from hardware and software attacks
  • Limit the attack surface for critical assets -
    • Isolate critical assets in protected space with heavily restricted access. Focus on protection against class-based attacks.
    • Assume rest of system is compromised to protect critical assets.
  • Sand-box security -
    • Security operates in isolated environment.
    • Application modules/tasks are securely isolated from each other, even on the same CPU.
  • Layered security -
    • Multi-tier approach, such that compromises do not spread and break the entire system security.
    • Each tier operates in isolation with other tiers.
  • Traceability, accountability and isolation for security development -
    • Security must be developed in isolated environment so that unexpected potential leaks are avoided.
    • This is also required to prove security to certification entities and customers.
