Mutual authentication or two-way authentication (not to be confused with two-factor authentication) refers to two parties authenticating each other at the same time in an authentication protocol. It is a default mode of authentication in some protocols ( IKE , SSH ) and optional in others ( TLS ).
TLS-SRP provides mutual authentication (the client and server both authenticate each other), while TLS with server certificates only authenticates the server to the client. Client certificates can authenticate the client to the server, but it may be easier for a user to remember a password than to install a certificate.
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet.The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible.
The OIDC Token Bound Authentication specification enables OIDC implementations to apply Token Binding to the OIDC ID Token. This cryptographically binds the ID Token to the TLS connection over which the authentication occurred. This use of Token Binding protects the authentication flow from man-in-the-middle and token export and replay attacks.
The Lightweight Extensible Authentication Protocol (LEAP) method was developed by Cisco Systems prior to the IEEE ratification of the 802.11i security standard. [3] Cisco distributed the protocol through the CCX (Cisco Certified Extensions) as part of getting 802.1X and dynamic WEP adoption into the industry in the absence of a standard.
TLS 1.0+ for transport-level security; XML Signature and XML Encryption for message-level security; Requirements are often phrased in terms of (mutual) authentication, integrity, and confidentiality, leaving the choice of security mechanism to implementers and deployers.
TLS-PSK uses symmetric keys, shared in advance among the communicating parties, to establish a TLS connection. There are several reasons to use PSKs: Using pre-shared keys can, depending on the ciphersuite, avoid the need for public key operations. This is useful if TLS is used in performance-constrained environments with limited CPU power.
