1. A method for wireless communication performed by a first multi-link device (MLD), the method comprising:
transmitting a beacon frame to a second MLD, the beacon frame including a first plurality of medium access control (MAC) addresses of respective first devices associated with the first MLD;
receiving an association request from the second MLD, the association request including a second plurality of MAC addresses of respective second devices associated with the second MLD;
generating, during a handshake operation with the second MLD, one or more encryption keys configured to encrypt communications between the first MLD and the second MLD;
receiving an Extensible Authentication Protocol (EAP) over local area network (LAN) (EAPoL) message that includes a first set of key data encapsulations (KDEs) encapsulating an address of the second MLD and a third plurality of MAC addresses; and
verifying the second plurality of MAC addresses based at least in part on the one or more encryption keys and the first set of KDEs.
