Extensible Authentication Protocol–Transport Layer Security (EAP-TLS) is an IETF open standard defined in RFC 5216. More colloquially, EAP-TLS is the authentication protocol most commonly deployed on WPA2-Enterprise networks to enable the use of X.509 digital certificates for authentication. EAP-TLS is ...
