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). One particular attack is always possible against keys, the brute force key space search attack. The secret is used by all systems involved in the cryptographic processes used to secure the traffic between the systems.Ĭrypto systems rely on one or more keys for confidentiality. It can be a password, a passphrase, or a hexadecimal string. The characteristics of this secret or key are determined by the system which uses it some system designs require that such keys be in a particular format. In all these cases, both the wireless access points (AP) and all clients share the same key. The term PSK is used in Wi-Fi encryption such as Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), where the method is called WPA-PSK or WPA2-PSK, and also in the Extensible Authentication Protocol (EAP), where it is known as EAP-PSK. Such systems almost always use symmetric key cryptographic algorithms. To build a key from shared secret, the key derivation function is typically used. ![]() ![]() ![]() 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. ![]()
