Inner Authentication
Method
Select the authentication method used inside the tunnel. Select from:
• CHAP – Challenge-Handshake Authentication Protocol (CHAP) provides
security by the Challenge-Response method of authentication.
• MS CHAP - Microsoft CHAP (MS CHAP) is Microsoft’s implementation of
the CHAP protocol.
• MS CHAP v2 – An enhanced version of MS CHAP that plugs some
security loopholes of MS CHAP.
• PAP – Password Authentication Protocol (PAP) is a basic authentication
protocol that transmits unencrypted ASCII passwords over the network.
• MD5 – Message Digest algorithm 5 (MD5) is a cryptographic hash
algorithm that uses a 128-bit hash value.
• GTC – Generic Token Card (GTC) is a protocol that enables the exchange
of clear-text authentication credentials across a network. This protocol
uses one-time password and therefore is not vulnerable to replay attacks.
EAP-GTC is generally used inside a tunnel created by TTLS or PEAP to
provide server authentication.
