8.5 Cryptography

The CC2340R device comes with AES-128 cryptography hardware accelerator, 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 AES hardware accelerators supports the following block cipher modes and message authentication codes:

  • AES ECB encrypt
  • AES CBC encrypt
  • AES CTR encrypt/decrypt
  • AES CBC-MAC
  • AES GCM
  • AEC CCM (uses a combination of CTR + CBC-MAC hardware via software drivers)

The AES hardware accelerator can be fed with plaintext/ciphertext from either CPU or using DMA. Sustained throughput of one 16 byte ECB block per 23 cycles is possible corresponding to > 30Mbps.

The CC2340R device supports Random Number Generation (RNG) using on-chip analog noise as the non-deterministic noise source for the purpose of generating a seed for a cryptographically secure counter deterministic random bit generator (CTR-DRBG) that in turn is used to generate random numbers for keys, initialization vectors (IVs), and other random number requirements. Hardware acceleration of AES CTR-DRBG is supported.

The CC2340R device includes a complete SHA 256 library in ROM, reducing the code footprint of the application. Uses cases may include generating digests for use in digital signature algorithms, data integrity checks, and password storage.

Together with 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.
