TLS

Transport Layer Security. A type of authentication method using the

Extensible Authentication Protocol (EAP) and a security protocol called the

Transport Layer Security (TLS). EAP-TLS uses certificates which use

passwords. EAP-TLS authentication supports dynamic WEP key

management. The TLS protocol is intended to secure and authenticate

communications across a public network through data encryption. The TLS

Handshake Protocol allows the server and client to provide mutual

authentication and to negotiate an encryption algorithm and cryptographic

keys before data is transmitted.

TTLS

Tunneled Transport Layer Security. These settings define the protocol and

the credentials used to authenticate a user. In TTLS, the client uses EAP-

TLS to validate the server and create a TLS-encrypted channel between

the client and server. The client can use another authentication protocol,

typically password-based protocols, such as MD5 Challenge over this

encrypted channel to enable server validation. The challenge and response

packets are sent over a non-exposed TLS encrypted channel. TTLS

implementations today support all methods defined by EAP, as well as

several older methods (CHAP, PAP, MS-CHAP and MS-CHAPv2). TTLS can

easily be extended to work with new protocols by defining new attributes

to support new protocols.

WEP

Wired Equivalent Privacy. Wired Equivalent Privacy, 64- and 128-bit (64-

bit is sometimes referred to as 40-bit). This is a low-level encryption

technique designed to give the user about the same amount of privacy

that he would expect from a LAN. WEP is a security protocol for wireless

local area networks (WLANs) defined in the 802.11b standard. WEP is

designed to provide the same level of security as that of a wired LAN. WEP

aims to provide security by data over radio waves so that it is protected as

it is transmitted from one end point to another.

WEP Key

Either a pass phrase or hexadecimal key.

The pass phrase must be 5 ASCII characters for 64-bit WEP or 13 ASCII

characters for 128-bit WEP. For pass phrases, 0-9, a-z, A-Z, and ~!@#$%

^&*()_+|`-={}|[]\:";'<>?,./ are all valid characters.

The hex key must be 10 hexadecimal characters (0-9, A-F) for 64-bit WEP

or 26 hexadecimal characters (0-9, A-F) for 128-bit WEP.

Wi-Fi

Wireless Fidelity. Is meant to be used generically when referring of any

type to 802.11 network, whether 802.11b, 802.11a, or dual-band.

Wireless

Router

A stand-alone wireless hub that allows any computer that has a wireless

network adapter to communicate with another computer and to connect to

the Internet. Also known as an access point.

WLAN

Wireless Local-Area Network. A type of local-area network that uses high-

frequency radio waves rather than wires to communicate between nodes.
