8.6 Cryptography

The CC27xx devices also integrate LAES, an AES-128 cryptography hardware accelerator (outside the HSM), to support latency-critical link-layer encryption/decryption operations prescribed by the wireless protocols. It also has the benefit of being lower power and improves the availability and responsiveness of the system because the cryptography operations run in a background hardware thread. The AES hardware accelerator supports the following block cipher modes and message authentication codes:

  • AES ECB encrypt-only
  • AES CBC encrypt-only
  • AES CTR encrypt/decrypt
  • AES CBC-MAC
  • AEC CCM (uses a combination of CTR + CBC-MAC hardware via software drivers)
Software implementation of AES GCM cipher mode using LAES for low-level cryptographic operations is supported. The AES hardware accelerator can be fed with plaintext/ciphertext from either the CPU or using DMA. Sustained throughput of one 16-byte ECB block per 23 cycles is possible, corresponding to > 30Mbps.
