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 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-CHAP-
V2). 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.
