Abstract
Authenticated encryption algorithms may function in both a data encryption and authentication operational mode as well as an authentication only operational mode. A first circuit may generate encrypted data and generate a first authentication tag. The first circuit may output for transmission as part of an MPDU, the first authentication tag and either the encrypted data or plaintext data based a control flag. A receiver device may receive the MPDU and a second encryption circuit of the receiver device may receive the first authentication tag and, based on a control flag, receive either the plaintext data or the encrypted data and from the MPDU and generate a second authentication tag by encrypting the plaintext data or decrypting the encrypted data depending on which is received. The second circuit may verify that management frames of the MPDU are valid/have not been tampered with if the first and second authentication tags match.
