Definitions

Authentication methods in wireless networks allow the wireless access point (AP) or broadband wireless router to authorize individuals and devices, and only those who get authorized can access the network. For maximum security, client devices should also authenticate to the wireless network using pre-shared key (PSK) or Extensible Authentication Protocol (EAP) authentication. The use of mutual authentication is essential in a wireless network. This will guard against many security issues, such as man-in-the-middle (MITM) attacks. With authentication, the wireless client and the wireless AP must prove their identity to each other.

Historical Background

When setting up a wireless network, the network administrator has to have some way to ensure that wireless clients, and the devices they are using, are trusted. A typical solution to this question is to use a standard kind of authentication, which in today’s...
