  • Secure content delivery – Allows encrypted file transfer to the system using asymmetric keys created by the device

Code and Data Security:

  • Network passwords and certificates are encrypted and signed.
  • Cloning protection – Application and data files are encrypted by a unique key per device.
  • Access control – Access to application and data files only by using a token provided in file creation time. If an unauthorized access is detected, a tamper protection lockdown mechanism takes effect.
  • Encrypted and Authenticated file system
  • Secured boot – Authentication of the application image on every boot
  • Code and data encryption – User application and data files are encrypted in sFlash.
  • Code and data authentication – User Application and data files are authenticated with a public key certificate.
  • Offloaded crypto library for asymmetric keys, including the ability to create key-pair, sign and verify data buffer
  • Recovery mechanism

Device Security:

  • Separate execution environments – Application processor and network processor run on separate Arm® cores
  • Initial secure programming – Allows for keeping the content confidential on the production line
  • Debug security
    • JTAG lock
    • Debug ports lock
  • True random number generator

Figure 9-1 shows the high-level structure of the CC3220S and CC3220SF devices that are contained within the CC3220MODS and CC3220MODSF modules, respectively. The application image, user data, and network information files (passwords, certificates) are encrypted using a device-specific key.
