Challenge-response authentication can help solve the problem of exchanging session keys for encryption. Using a key derivation function, the challenge value and the secret may be combined to generate an unpredictable encryption key for the session. This is particularly effective against a man-in-the-middle attack, because the attacker will not ...
Digest access authentication is one of the agreed-upon methods a web server can use to negotiate credentials, such as username or password, with a user's web browser. This can be used to confirm the identity of a user before sending sensitive information, such as online banking transaction history.
That is, guards are engineered to provide assurance that they apply the appropriate checks. [7] Guards can use a trusted operating system to separate the security critical checker components from the less critical protocol handling components. In this way failure of the protocol handling components cannot cause data to bypass the checker. [8]
It supports network-level peer authentication, data origin authentication, data integrity, data confidentiality , and protection from replay attacks. The protocol was designed by a committee instead of being designed via a competition, it was made so complex with a lot of options which has a devastating effect on a security standard. [ 2 ]

Then he sends a packet saying "Authentication successful" or "Authentication failed" based on the result. [3] This is an example of a very basic authentication protocol vulnerable to many threats such as eavesdropping, replay attack, man-in-the-middle attacks, dictionary attacks or brute-force attacks. Most authentication protocols are more ...
SAML is an XML-based markup language for security assertions (statements that service providers use to make access-control decisions). SAML is also: A set of XML-based protocol messages; A set of protocol message bindings; A set of profiles (utilizing all of the above) An important use case that SAML addresses is web-browser single sign-on (SSO).
Extensible Authentication Protocol (EAP) is an authentication framework frequently used in network and internet connections. It is defined in RFC 3748, which made RFC 2284 obsolete, and is updated by RFC 5247. EAP is an authentication framework for providing the transport and usage of material and parameters generated by EAP methods.
