• 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.

TI delivers two primary software components as part of TIFS-SDK:

• OTP Key Provisioning Package
• TIFS-MCU (TI's Foundational Security) Add-on Package
