Wireless Networks called WiFi, permit you to attach to the internet devoid of relying on wires. If your home, office, airport, or even local coffee shop has a wireless connection, you can way in the system from anywhere that is within that wireless area. ...

Current iterations of Wi-Fi boast ranges of around 40 meters inside a building and up to 90 meters outside. Those distances, combined with the sheer number of Wi-Fi networks out there, mean that an active wireless client is often within range of tens if not hundreds of wireless networks at ...

Disabling ad-hoc networking is one way to prevent a computer from connecting to wireless networks indiscriminately. Turning the dang radio off is a sure-fire way, and users should do that whenever they're working offline. You wouldn't leave the engine running at a drive-in movie, would you? Here's how to turn ...

Available in coffee shops, hotels, airport terminals and libraries, public Wi-Fi hot spots have become almost as common as public toilets. There are more than 150,000 wireless LAN hotspots worldwide today, a number that will grow to more than 200,000 by the end of 2008, according to research firm Gartner, ...

Securing a wireless network requires authentication and encryption technologies. Authentication is the process of ensuring that a user is authorized to access the wireless network. For personal networks, authentication is usually handled with a username and password. In the corporate environment, authentication technologies include digital certificates, smart cards, and biometric ...

The current implementations of code signalling, message delivery, and code protocol fall short of providing adequate call party authentication, end-to-end integrity, and confidentiality of messages with VoIP. VoIP converts voice signals from the telephone into digital signals ...

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 ...
