The IEEE 802.15.4 is a specification for the physical and MAC layers of wireless personal area networks.

Security

IEEE 802.15.4 media access control layer defines different security modes based on the AES block cipher:

  • Null: neither encryption nor authentication. Default mode.
  • Counter mode (CTR): Encryption only. No authentication.
  • Cipher Block Chaining Message Authentication Code (CBC-MAC): Authentication only.
  • Counter with CBC-MAC (CCM): Encryption and authentication.

For the last two modes, the authentication tag can be 32, 64 or 128 bits.
