Password authentication is less prone than certificate authentication to certain types of configuration mistakes, such as expired certificates or mismatched common name fields. 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.
The second set use a Diffie–Hellman key exchange authenticated with a pre-shared key. The third set combine public key authentication of the server with pre-shared key authentication of the client. Usually, Transport Layer Security (TLS) uses public key certificates or Kerberos for authentication. TLS-PSK uses symmetric keys, shared in ...
An alternative approach to the problem of public authentication of public key information is the web-of-trust scheme, which uses self-signed certificates and third-party attestations of those certificates. The singular term "web of trust" does not imply the existence of a single web of trust, or common point of trust, but rather one of any ...
Mutual authentication is a desired characteristic in verification schemes that transmit sensitive data, in order to ensure data security. [1] [2] Mutual authentication can be accomplished with two types of credentials: usernames and passwords, and public key certificates. Mutual authentication is often employed in the Internet of Things (IoT ...
In cryptography, X.509 is an International Telecommunication Union (ITU) standard defining the format of public key certificates. [1] X.509 certificates are used in many Internet protocols, including TLS/SSL, which is the basis for HTTPS, [2] the secure protocol for browsing the web.
Mutual EAP authentication: support for EAP-only (i.e., certificate-less) authentication of both of the IKE peers; the goal is to allow for modern password-based authentication methods to be used (RFC 5998). Quick crash detection: minimizing the time until an IKE peer detects that its opposite peer has crashed (RFC 6290).
EAP with the encrypted key exchange, or EAP-EKE, is one of the few EAP methods that provide secure mutual authentication using short passwords and no need for public key certificates. It is a three-round exchange, based on the Diffie-Hellman variant of the well-known EKE protocol. EAP-EKE is specified in RFC 6124.
The protocol enables users to securely exchange secret keys even if an opponent is monitoring that communication channel. The D–H key exchange protocol, however, does not by itself address authentication (i.e. the problem of being sure of the actual identity of the person or 'entity' at the other end of the communication channel).
