1. A transmitting multi-link device (MLD) comprising a first plurality of affiliated Access Points (AP), the MLD comprising:
circuitry, which, in operation, encapsulates a plaintext medium access control (MAC) protocol data unit (MPDU), an Additional Authentication Data (AAD), and a Nonce to generate an encapsulated MPDU, wherein the AAD includes an Address 1 (A1) field, which is set to an MLD MAC address of a recipient MLD, and an Address 2 (A2) field, which is set to an MLD MAC address of the transmitting MLD, and wherein the Nonce includes an Address 2 (A2) field, which is set to the MLD MAC address of the transmitting MLD; and
a transmitter, which, in operation, transmits the encapsulated MPDU to the recipient MLD on a first link.
