  2. TLS-PSK - Wikipedia

    en.wikipedia.org/wiki/TLS-PSK

    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 ...

  3. Pre-shared key - Wikipedia

    en.wikipedia.org/wiki/Pre-shared_key

    Unavoidably, however, pre-shared keys are held by both parties to the communication, and so can be compromised at one end, without the knowledge of anyone at the other. There are several tools available to help one choose strong passwords, though doing so over any network connection is inherently unsafe as one cannot in general know who, if ...

  4. Shared secret - Wikipedia

    en.wikipedia.org/wiki/Shared_secret

    The shared secret is either shared beforehand between the communicating parties, in which case it can also be called a pre-shared key, or it is created at the start of the communication session by using a key-agreement protocol, for instance using public-key cryptography such as Diffie–Hellman or using symmetric-key cryptography such as Kerberos.

  5. Internet Key Exchange - Wikipedia

    en.wikipedia.org/wiki/Internet_Key_Exchange

    The authentication can be performed using either pre-shared key (shared secret), signatures, or public key encryption. [12] Phase 1 operates in either Main Mode or Aggressive Mode. Main Mode protects the identity of the peers and the hash of the shared key by encrypting them; Aggressive Mode does not. [10]

  6. Extensible Authentication Protocol - Wikipedia

    en.wikipedia.org/wiki/Extensible_Authentication...

    1] EAP Pre-shared key (EAP-PSK), defined in RFC 4764, is an EAP method for mutual authentication and session key derivation using a pre-shared key (PSK). It provides a protected communication channel, when mutual authentication is successful, for both parties to communicate and is designed for authentication over insecure networks such as IEEE ...

  7. IPsec - Wikipedia

    en.wikipedia.org/wiki/IPsec

    IPsec includes protocols for establishing mutual authentication between agents at the beginning of a session and negotiation of cryptographic keys to use during the session. IPsec can protect data flows between a pair of hosts ( host-to-host ), between a pair of security gateways ( network-to-network ), or between a security gateway and a host ...

  8. IEEE 802.11i-2004 - Wikipedia

    en.wikipedia.org/wiki/IEEE_802.11i-2004

    The initial authentication process is carried out either using a pre-shared key (PSK), or following an EAP exchange through 802.1X (known as EAPOL, which requires the presence of an authentication server). This process ensures that the client station (STA) is authenticated with the access point (AP).

  9. X.1035 - Wikipedia

    en.wikipedia.org/wiki/X.1035

    ITU-T Recommendation X.1035 specifies a password-authenticated key agreement protocol that ensures mutual authentication of two parties by using a Diffie–Hellman key exchange to establish a symmetric cryptographic key. The use of Diffie-Hellman exchange ensures perfect forward secrecy—a property of a key establishment protocol that ...
