The list of type and packets codes used in EAP is available from the IANA EAP Registry. Requirements for EAP methods used in wireless LAN authentication are described in RFC 4017. Commonly used modern methods capable of operating in wireless networks include EAP-TLS, EAP-SIM, EAP-AKA, LEAP and EAP-TTLS. Additionally, a number of vendor-specific methods and new proposals exist. Methods defined in IETF RFCs include EAP-MD5, EAP-POTP, EAP-GTC, EAP-TLS, EAP-IKEv2, EAP-SIM, EAP-AKA, and EAP-AKA'. There are currently about 40 different methods defined. It provides some common functions and negotiation of authentication methods called EAP methods. For example, in IEEE 802.11 (WiFi) the WPA and WPA2 standards have adopted IEEE 802.1X (with various EAP types) as the canonical authentication mechanism.ĮAP is an authentication framework, not a specific authentication mechanism. Each protocol that uses EAP defines a way to encapsulate by the user EAP messages within that protocol's messages.ĮAP is in wide use. EAP is not a wire protocol instead it only defines the information from the interface and the formats. There are many methods defined by RFCs, and a number of vendor-specific methods and new proposals exist. It is defined in RFC 3748, which made RFC 2284 obsolete, and is updated by RFC 5247.ĮAP is an authentication framework for providing the transport and usage of material and parameters generated by EAP methods. Authentication protocol for the point-to-point protocolĮxtensible Authentication Protocol ( EAP) is an authentication framework frequently used in network and internet connections.
