EAP (Extensible Authentication Protocol)

February 29, 2024
EAP is an Extended Authentication Protocol that is used to transfer authentication information between a requesting party and an authentication server. The authentication framework is often used in wireless networks and point-to-point connections and is designed to support multiple authentication methods. It is a powerful tool for authenticating and controlling access to networks and computing resources.
This is a set of internal components to support any type of EAP in the form of a plug-in module. The module must be identical on the remote access client and on the authentication device.

EAP Methods

  • EAP-TLS is a standard EAP method that uses TLS with certificates for mutual authentication.
  • EAP-MSCHAPv2 – Microsoft’s EAP method that uses a username and password for authentication.
  • EAP-TTLS – The method encapsulates a TLS session that performs mutual authentication using an internal validation mechanism.
  • EAP-SIM – The subscriber credential module provides authentication using a SIM card.
  • TEAP-The EAP tunnel method that establishes a secure TLS tunnel and performs other EAP methods within that tunnel.
