Cards

Term
AES-CCMP
Definition
An advanced security encryption protocol used in the Wi-Fi Protected Access 2 (WPA2) standard.
Term
association request frame
Definition
A frame that carries information about the data rates that the device can support along with the Service Set identifier (SSID) of the network it wants to join.
Term
authentication server
Definition
A server whose only job is to verify the authentication of devices.
Term
ciphertext
Definition
Encrypted text.
Term
Collision
Definition
Two packets derived from the same initialization vector (IV).
Term
cyclic redundancy check (CRC)
Definition
A checksum based on the contents of the text.
Term
handoff
Definition
Associating with a new access point.
Term
IEEE 802.11a
Definition
A 1999 standard with a maximum rated speed of 54 Mbps using the 5 GHz spectrum.
Term
IEEE 802.11b
Definition
A 1999 amendment to the 802.11 Standard that added 2 higher speeds (5.5 Mbps and 11 Mbps).
Term
IEEE 802.11g
Definition
A standard formally ratified in 2003 for wireless LAN transmissions of devices transmitting at 54 Mbps.
Term
IEEE 802.11i
Definition
The 2004 wireless security standard that addresses the two main weaknesses of wireless networks, encryption and authentication.
Term
IEEE 802.11n
Definition
A proposed standard for faster wireless LANs projected to be ratified in 2009.
Term
IEEE 802.1x
Definition
A standard originally developed for wired networks that provides a greater degret of security for wireless networks by implementing port-based authentication.
Term
integrity check value (ICV)
Definition
A checksum based on the contents of the text used in WEP encryption.
Term
key-caching
Definition
Storing information from a device on the network so if a user roams away from wireless access point and later returns he does not need to re-enter all of the credentials.
Term
keystream
Definition
A series of 1s and Os equal in length to the text to be encrypted with Wired Equivalent Privacy (WEP) plus the integrity check value (1CV).
Term
keystream attack
Definition
An attack that attempts to determine thc keystream by analyzing two packets that were created from the same initialization vector (IV).
Term
Message Integrity Check (MIC)
Definition
A protocol designed to prevent an attacker from capturing, altering, and resending data packets.
Term
open system authentication
Definition
The default method of authentication used by the IEEE 802.11 standard.
Term
passive scanning
Definition
Scanning for a wireless device that listens for a beacon frame for a set period of time.
Term
plaintext
Definition
Unencrypted text.
Term
pre-authentication
Definition
A technology that allows a device to become authenticated to an access point before moving into its range.
Term
preshared key (PSK)
Definition
An authentication protocol that uses a passphrase to generate encryption key and must be created and entered into both the access point and all wireless devices prior to the devices communicating.
Term
RC4
Definition
A cipher algorithm used in Wired Equivalent Privacy (WEP) that takes one character and replaces it with one character.
Term
roaming
Definition
Movement between cells of a wireless local area network.
Term
Service Set Identifier (SSID)
Definition
The network name for the wireless network that can be any alphanumeric string from 2 to 32 characters.
Term
shared key authentication
Definition
An optional Wired Encryption Privacy (WEP) authentication that uses challenge text for authentication.
Term
Temporal Key Integrity Protocol (TKIP)
Definition
A encryption technology that replaces the Wired Equivalent Privacy (WEP) protocol.
Term
thin access point
Definition
An access point with limited functionality (it does not provide authentication or encryption).
Term
Wi-Fi (Wireless Fidelity) Alliance
Definition
A consortium of wireless equipment manufacturers and software providers to promote wireless network technology.
Term
Wi-Fl Protected Access (WPA)
Definition
The first version of the security standards set by the Wi-Fi Alliance.
Term
WI-Fl Protected Access 2 (WPA2)
Definition
The second generation of Wi-Fi Protected Access (WPA) security.
Term
Wired Equivalent Privacy (WEP)
Definition
The encryption mechanism of thc IEEE 802.11 standard, considered to provide only low security.
Term
wireless probe
Definition
A device that can monitor the airwaves for traffic.
Term
wireless switch
Definition
A switch that contains authentication and encryption for wireless networks.
