  2. Pre-shared key - Wikipedia

    en.wikipedia.org/wiki/Pre-shared_key

    A sufficiently long, randomly chosen, key can resist any practical brute force attack, though not in principle if an attacker has sufficient computational power (see password strength and password cracking for more discussion). Unavoidably, however, pre-shared keys are held by both parties to the communication, and so can be compromised at one ...

  3. Wi-Fi Protected Access - Wikipedia

    en.wikipedia.org/wiki/Wi-Fi_Protected_Access

    Initially, devices associate with the Access Point (AP) via an association request. This is followed by a 4-way handshake, a crucial step ensuring both the client and AP have the correct Pre-Shared Key (PSK) without actually transmitting it. During this handshake, a Pairwise Transient Key (PTK) is generated for secure data exchange. [12]

  4. TLS-PSK - Wikipedia

    en.wikipedia.org/wiki/TLS-PSK

    Transport Layer Security pre-shared key ciphersuites (TLS-PSK) is a set of cryptographic protocols that provide secure communication based on pre-shared keys (PSKs). These pre-shared keys are symmetric keys shared in advance among the communicating parties.

    After the PSK or 802.1X authentication, a shared secret key is generated, called the Pairwise Master Key (PMK). In PSK authentication, the PMK is actually the PSK, [6] which is typically derived from the WiFi password by putting it through a key derivation function that uses SHA-1 as the cryptographic hash function. [7]

  6. Wi-Fi Protected Setup - Wikipedia

    en.wikipedia.org/wiki/Wi-Fi_Protected_Setup

    A major security flaw was revealed in December 2011 that affects wireless routers with the WPS PIN feature, which most recent models have enabled by default. The flaw allows a remote attacker to recover the WPS PIN in a few hours with a brute-force attack and, with the WPS PIN, the network's WPA/WPA2 pre-shared key (PSK). [3]

  7. 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 ...

  8. Protected Extensible Authentication Protocol - Wikipedia

    en.wikipedia.org/wiki/Protected_Extensible...

    PEAP is similar in design to EAP-TTLS, requiring only a server-side PKI certificate to create a secure TLS tunnel to protect user authentication, and uses server-side public key certificates to authenticate the server. It then creates an encrypted TLS tunnel between the client and the authentication server. In most configurations, the keys for ...

  9. Temporal Key Integrity Protocol - Wikipedia

    en.wikipedia.org/wiki/Temporal_Key_Integrity...

    Temporal Key Integrity Protocol (TKIP / t iː ˈ k ɪ p /) is a security protocol used in the IEEE 802.11 wireless networking standard. TKIP was designed by the IEEE 802.11i task group and the Wi-Fi Alliance as an interim solution to replace WEP without requiring the replacement of legacy hardware.
