  2. Pre-shared key - Wikipedia

    en.wikipedia.org/wiki/Pre-shared_key

    In cryptography, a pre-shared key (PSK) is a shared secret which was previously shared between the two parties using some secure channel before it needs to be used. [ 1 ] Key

  3. TLS-PSK - Wikipedia

    en.wikipedia.org/wiki/TLS-PSK

    Usually, Transport Layer Security (TLS) uses public key certificates or Kerberos for authentication. 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.

  4. Wi-Fi Protected Access - Wikipedia

    en.wikipedia.org/wiki/Wi-Fi_Protected_Access

    Also referred to as WPA-PSK (pre-shared key) mode, this is designed for home, small office and basic uses and does not require an authentication server. [24] Each wireless network device encrypts the network traffic by deriving its 128-bit encryption key from a 256-bit shared key.

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

    IEEE 802.11i enhances IEEE 802.11-1999 by providing a Robust Security Network (RSN) with two new protocols: the four-way handshake and the group key handshake. These utilize the authentication services and port access control described in IEEE 802.1X to establish and change the appropriate cryptographic keys.

  6. Simultaneous Authentication of Equals - Wikipedia

    SAE was originally implemented for use between peers in IEEE 802.11s. [1] When peers discover each other (and security is enabled) they take part in an SAE exchange. If SAE completes successfully, each peer knows the other party possesses the mesh password and, as a by-product of the SAE exchange, the two peers establish a cryptographically strong key.

    SAs contain all the information required for execution of various network security services, such as the IP layer services (such as header authentication and payload encapsulation), transport or application layer services or self-protection of negotiation traffic. ISAKMP defines payloads for exchanging key generation and authentication data.

  9. Network security - Wikipedia

    en.wikipedia.org/wiki/Network_security

    Network security covers a variety of computer networks, both public and private, that are used in everyday jobs: conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.
