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

Physical layer

Media access control

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.
