Complete Protocol dictionary, glossary and reference
802.1x is an IEEE standard for port-based network access control, particularly useful for securing 802.11 wireless local area networks (WLANs). The IEEE 802.1X offers an effective framework for authenticating and controlling user traffic to a protected network, as well as dynamically varying encryption keys. 802.1X ties a protocol called EAP (Extensible Authentication Protocol) to both the wired and wireless LAN media and supports multiple authentication methods, such as token cards, Kerberos, one-time passwords, certificates and public key authentication. Therefore, 802.1X is also known as EAP over LAN (EAPOL).
