- EAP
Extensible Authentication Protocol. EAP is a general protocol for authentication that also supports multiple authentication methods, such as token cards, Kerberos, one-time passwords, certificates, public key authentication, and smart cards.
- EAPoL
EAP over LAN. A message structure for sending EAP packets in an 802.1x framework.
- EAP-FAST
Extensible Authentication Protocol-Flexible Authentication via Secure Tunneling. An EAP mechanism proposed by Cisco Systems that provides robust and secure authentication through the use of encrypted tunnels. Unlike PEAP or EAP-TLS, EAP-FAST does not require certificates on clients or servers.
- EAP-TLS
Extensible Authentication Protocol with Transport Layer Security. EAP-TLS is one of the many EAP mechanisms for 802.1x-based authentication. It uses certificates to ensure mutual authentication between the client device and the authenticator and AAA servers.
- EAP-TTLS
Extensible Authentication Protocol with Tunneled Transport Layer Security. EAP-TTLS is a proprietary EAP mechanism developed by Funk Software, Inc., (prior to their acquisition by Juniper Networks) and Certicom for 802.1x authentication. TTLS uses a combination of certificates and password challenge and response for authentication and encrypts the entire EAP session in a TLS tunnel.
- encryption
Encryption is the process of changing data into a form that can be read, or decrypted, only by the intended receiver. Encryption uses a "key" to scramble the data. This can be shared via a public key infrastructure (PKI) system, or both ends of the transmission can use pre-shared keys.
- ESS
Extended Service Set. Multiple basic service sets (BSS) linked by a backbone network to form a single subnetwork.
- ETSI
European Telecommunications Standards Institute. The primary telecommunication standards organization in Europe.
- EWC
Enhanced Wireless Consortium. An industry consortium of leading wireless industry members formed to accelerate the ratification and adoption of the upcoming 802.11n standard and to ensure interoperability between member-developed products.
