With respect to the International Standards Organization’s (ISO) seven layer Open Systems Interconnection (OSI) model, the 802.11 standard directs only layer one (Physical) and layer two (Data Link or Medium Access Control (MAC)) specifications. The encapsulation of data within each successive layer enables all lower layers to function without regard for their higher layer payloads. This chapter ...

The 802.11 standard describes the communication that occurs in wireless local area networks (LANs). The Wired Equivalent Privacy (WEP) algorithm is used to protect wireless communication from eavesdropping. A secondary function of WEP is to prevent unauthorized access to a wireless network; this function is not an explicit ...

 A passive eavesdropper can intercept all wireless traffic, until an IV collision occurs. By XORing two packets that use the same IV, the attacker obtains the XOR of the two plaintext messages. The resulting XOR can be used to infer data about the contents of the two messages. IP traffic ...

When setting up a system which strictly demands the usage of WEP encryption for all data transmissions, all the WavePOINTs in the system must be configured to have the parameter “Deny non-encrypted Data” set to ON (checked in the tickbox). This will assure that only stations with WEP encryption enabled can connect to the ...

The 802.11b standard includes a provision for encryption called WEP (Wired Equivalent Privacy). Depending on the manufacturer and the model of the NIC card and access point, there are two levels of WEP commonly available - one based on a 40-bit encryption key and 24-bit Initialization Vector (also called 64-bit ...
