12 PIC32CM SG00/GC00 Security Features

The following are security features of the PIC32CK SG/GC family of devices:

• Built-in cryptographic accelerator accessible through cryptographic libraries stored in ROM:
  • Supporting AES-128 encryption/decryption, SHA-256 authentication, GCM encryption, and authentication
  • Cryptographic libraries are especially designed for side channel and fault injection attacks prevention
• One True Random Generator (TRNG)
• Secure Boot, which performs integrity check on a configurable portion of the Flash (BS memory area)

• Data Flash
  • Optimized for secrets storage
  • Data Scrambling with user-defined key (optional)
  • Rapid Tamper erase on scrambling key and on one user-defined row
  • Silent access for side channel attack resistance
• TrustRAM
