Abstract: A secure Simultaneous Authentication of Equals (SAE) anti-clogging mechanism may be provided. A public key of an access point may be provided from the access point to a client attempting to connect with a network via the access point. The access point may receive from the client a first anti-clogging token and a public key of the client. The first anti-clogging token may be generated by the first client using a shared secret based on a private key of the client and the public key of the access point and a multiplier. The access point may generate a second anti-clogging token using a shared secret based on a private key of the access point and the public key of the client and the multiplier. The access point may then verify the first anti-clogging token and the second anti-clogging token match to authenticate the client.
