This reduces resource requirements for both client and server, and minimizes the number of times that users are prompted for credentials.Ĭryptobinding: By deriving and exchanging values from the PEAP phase 1 key material ( Tunnel Key) and from the PEAP phase 2 inner EAP method key material ( Inner Session Key), it is possible to prove that the two authentications terminate at the same two entities (PEAP peer and PEAP server). Inner method - the outer method creates a secure tunnel inside while the inner method is used to complete the authentication:įast Reconnect: reduces the delay between an authentication request by a client and the response by the Network Policy Server (NPS) or other Remote Authentication Dial-in User Service (RADIUS) server. Server validation - with PEAP, server validation can be toggled on or off: Protected Extensible Authentication Protocol (PEAP): Notification - specify if the user should get a notification asking whether to trust the server or not.Server certificate - trusted root certificate to validate the server.Server name - specify the server to validate.Server validation - with TLS, server validation can be toggled on or off: Filtering can be Issuer-based or Enhanced Key Usage (EKU)-based.Certificate filtering can be enabled to search for a particular certificate to use to authenticate with.Certificate with keys in Trusted Platform Module (TPM) KSP.Certificate with keys in the software Key Storage Provider (KSP).Supports the following types of certificate authentication: Winlogon credentials - can specify authentication with computer sign-in credentials.Windows supports a number of EAP authentication methods.ĮAP-Microsoft Challenge Handshake Authentication Protocol version 2 (EAP-MSCHAPv2): You can only configure EAP-based authentication if you select a built-in VPN type (IKEv2, L2TP, PPTP or Automatic). In addition to older and less-secure password-based authentication methods (which should be avoided), the built-in VPN solution uses Extensible Authentication Protocol (EAP) to provide secure authentication using both user name and password, and certificate-based methods.
