9.5 Cryptography

The CC2651R3 device comes with a wide set of cryptography-related hardware accelerators, reducing code footprint and execution time for cryptographic operations. It also has the benefit of being lower power and improves availability and responsiveness of the system because the cryptography operations run in a background hardware thread.
The hardware accelerator modules are:

  • True Random Number Generator (TRNG) module provides a true, nondeterministic noise source for the purpose of generating keys, initialization vectors (IVs), and other random number requirements. The TRNG is built on 24 ring oscillators that create unpredictable output to feed a complex nonlinear-combinatorial circuit.
  • Advanced Encryption Standard (AES) with 128 bit key lengths

Together with the hardware accelerator module, a large selection of open-source cryptography libraries provided with the Software Development Kit (SDK), this allows for secure and future proof IoT applications to be easily built on top of the platform. The TI provided cryptography drivers are:

  • Key Agreement Schemes
    • Elliptic curve Diffie–Hellman with static or ephemeral keys (ECDH and ECDHE)
  • Signature Generation
    • Elliptic curve Diffie-Hellman Digital Signature Algorithm (ECDSA)
  • Curve Support
    • Short Weierstrass form (full hardware support), such as:
      • NIST-P256
    • Montgomery form (hardware support for multiplication), such as:
      • Curve25519
  • Hash
    • SHA256
  • MACs
    • HMAC with SHA256
    • AES CBC-MAC
  • Block ciphers
    • AESECB
    • AESCBC
    • AESCTR
  • Authenticated Encryption
    • AESCCM
  • Random number generation
    • True Random Number Generator
    • AES CTR DRBG
