Temporal Key Integrity Protocol (TKIP)
A data encryption method designed as a replacement for WEP. TKIP avoids the problems of WEP
static keys by dynamically changing data encryption keys.
Trivial File Transfer Protocol (TFTP)
A TCP/IP protocol commonly used for software downloads.
Virtual LAN (VLAN)
A Virtual LAN is a collection of network nodes that share the same collision domain regardless of
their physical location or connection point in the network. A VLAN serves as a logical workgroup with
no physical barriers, and allows users to share information and resources as though located on the
same LAN.
Wi-Fi Protected Access
WPA employs 802.1x as its basic framework for user authentication and dynamic key management
to provide an enhanced security solution for 802.11 wireless networks.
Wired Equivalent Privacy (WEP)
WEP is based on the use of security keys and the popular RC4 encryption algorithm. Wireless
devices without a valid WEP key will be excluded from network traffic.
WPA Pre-shared Key (PSK)
PSK can be used for small office networks that may not have the resources to configure and
maintain a RADIUS server, WPA provides a simple operating mode that uses just a pre-shared
password for network access.
