TKIP (Temporal Key Integrity Protocol)
Changes the encryption keys regularly and has time limits before new keys are created. Changing the
key periodically provides additional security.
TLS (Transport Layer Security)
A cryptographic protocol that uses client-side and server-side certicates to authenticate users on the
Web. It can dynamically create user-based and session-based keys.
TTLS (Tunneled Transport Layer Security)
Provides certicate-based, server-side, mutual authentication of the client and network through an
encrypted channel (or tunnel). It can dynamically create user-based and session-based keys.
WEP or Wired Equivalent Privacy
A security protocol for wireless local area networks. WEP was designed to provide the same level of
security as that of a wired network, which is inherently more secure than a wireless network because
wired networks are easily protected against unauthorized access. Wireless networks use radio waves to
communicate and can be vulnerable to unauthorized users. WEP provides security by encrypting data
over radio waves so that it is protected as it is transmitted. However, it has been found that WEP is not
as secure as once believed
128 Bit / 64 Bit WEP Key
This is the 64 or 128 bit WEP key that must match other Nodes’ encryption keys to communicate:
10 hex characters for 64 bit (40 serspeciedcharacters), or 26 hex characters for 128 bit (104 user-
specied characters). You must use the same key values for devices to
communicate with each other
WLAN or Wireless Local Area Network
A LAN that uses high-frequency radio waves to communicate between nodes, rather than telephone
wires, etc
WPA (Wi-Fi Protected Access)
A network security protocol that uses improved authentication and temporal keys. It was created to
address the weaknesses of WEP encryption.
WPA2(or IEEE 802.11i) :
A network security protocol with stronger encryption than WPA. It was created to address the
weaknesses of WEP encryption.
NOTE
If one part of a wireless network has WEP enabled, they all must have it enabled with the same key or they
cannot communicate.
