IEEE specification that describes the logical link control (LLC) encapsulation
common to all 802 series LANs.
802.3
An IEEE LAN specification for a Carrier Sense Multiple Access with Collision

media. An 802.3 frame uses source and destination media access control (MAC)
addresses to identify its originator and receiver(s).
authentication
The process that a station, device, or user employs to announce its identify to
the network which validates it. IEEE 802.11 specifies two forms of
authentication: open system and shared key. See also, 802.11x and
GL
authentication.
authorization
The process of deciding if device 'X' may use network service 'Y'. Trusted
devices (the devices that are both authenticated and authorized) are allowed
access to network services. Unknown (not trusted) devices may require further
user authorization to access network services. This does not principally exclude
that the authorization might be given by an application automatically.
Authorization always includes authentication. See also, authentication.
bandwidth
Specifies the amount of the frequency spectrum that is usable for data transfer.
In other words, it identifies the maximum data rate a signal can attain on the
medium without encountering significant attenuation (loss of power). See also,
bit rate.

baud rate
The number of pulses of a signal that occur in one second. Thus, baud rate is the

device retains the use of the IP address for a specific license period defined by
the system administrator.
EAP
(Extensible Authentication Protocol) A general point-to-point protocol that
supports multiple authentication mechanisms. Defined in RFC 2284, EAP has
been adopted by IEEE 802.1X as an encapsulation protocol for carrying
authentication messages in a standard message exchange between a user (client
or supplicant) and an authenticator. See also, 802.1X.
EAPoL
(EAP over LAN) An encapsulated form of the Extensible Authentication Protocol
(EAP), defined in the IEEE 802.1X standard, that allows EAP messages to be

(client or supplicant) and an authenticator. See also, 802.1X.
EAP-TLS
(Extensible Authentication Protocol with Transport Layer Security) Used for
802.1X authentication. EAP-TLS supports mutual authentication and uses digital
certificates to address the mutual challenge. The authentication server responds
to a user authentication request with a server certificate. The user then replies
with its own certificate and validates the server certificate. EAP-TLS algorithm
derives session encryption keys from the certificate values. The authentication
server in turn sends the session encryption keys for a particular session to the
user after validating the user certificate. See also, authentication and EAP.
encryption

decrypted and read only by its intended receiver.

FHSS
(Frequency-Hopping Spread-Spectrum) One of two types of spread-spectrum
radio technology used in wireless LAN (WLAN) transmissions. The FHSS
technique modulates the data signal with a narrowband carrier signal that
“hops” in a predictable sequence from frequency to frequency as a function of
time over a wide band of frequencies. Interference is reduced, because a
narrowband interferer affects the spread-spectrum signal only if both are
transmitting at the same frequency at the same time. The transmission
frequencies are determined by a spreading (hopping) code. The receiver must
be set to the same hopping code and must listen to the incoming signal at the
proper time and frequency to receive the signal.

PKCS
(Public-Key Cryptography Standards) A group of specifications produced by RSA

certificate signing requests and key exchanges.
PKI
(Public-Key Infrastructure) Software that enables users of an insecure public
network such as the Internet to exchange information securely and privately. PKI
uses public-key cryptography to authenticate the message sender and encrypt

with the same algorithm. A registration authority (RA) must verify the certificate
authority before a digital certificate is issued to a requestor. PKI uses the digital
