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.
