Abstract
A media access control (MAC) security apparatus including an encryption/decryption engine and an authentication engine. The encryption/decryption engine is configured to generate encrypted data based on received packets. The authentication engine is configured to perform authentication in response to the encrypted data. The encryption/decryption engine includes an advanced encryption standard (AES) engine configured to form cryptographic primitives. The AES engine is configured to enter a reduced power consumption state for part of a period during which the encryption/decryption engine is generating encrypted data based on the received packets.
