Abstract: This disclosure describes systems, methods, and devices related to security for multi-link operation. A device may determine a multi-link communication with a first multi-link device comprising two or more links associated with two or more station devices (STAs) included in the first multi-link device. The device may determine a first medium access control (MAC) address associated with a first link of the two or more links. The device may determine a second MAC address associated with a second link of the two or more links. The device may generate one or more pairwise security keys to be used in the multi-link communication on the two or more links. The device may cause to send a frame to the first multi-link device using at least one combination of the one or more pairwise security keys.

Abstract: A method and device for generating a shared session secret with forward secrecy between a first device and a second device. The first and second devices perform mutual authentication. The first and second devices establish a first shared secret using a key encapsulation mechanism with a long-term cryptographic key pair of the devices. The first and second devices generate an ephemeral cryptographic key pair comprising an ephemeral public key and an ephemeral private key, respectively, and transfer the ephemeral public key of the device to the other device using the first shared secret. The first and second devices then establish a second shared secret using the key encapsulation mechanism with the ephemeral public keys of the first device and the second device. The second shared secret is used as a temporary shared session secret.
