The Linksys Wireless-N router has a number of safety features. The safety features include: Wep, Psk Personal (Wpa), and Psk Personal (Wpa2). In this article, I will explicate characteristics of Wep. The explanation will not be very technical but more practical for daily decisions.
Wep is the oldest safety encryption feature of the home router. Wep stands for Wired Equivalent Privacy. Wep has a serious flaw. It is possible to achieve the strike with a personal computer, off-the-shelf hardware and freely available software such as aircrack-ng and crack any Wep key in one itsybitsy or less. One might say that a explication to the question would be to use higher bit keys. However, it is possible to recover a 104 bit Wep key with a 50% probability using just 40,000 captured packets. For 60,000 available data packets, the success rate is 80% and a 95% success rate for 85,000 data packets. Using active techniques like "deauth" and "Arp re-injection", 40,000 packets can be captured in less than one itsybitsy under good condition. The actual computation takes about 3 seconds and 3 Mb main memory on a Pentium-M 1.7 Ghz and can additionally be optimized for devices with slower Cpus. The same strike can be used for 40 bit keys too with an even higher success probability.
In 2005, a group from the Fbi demonstrated a crack of a Wep-protected network in 3 minutes using tools that are available to the public.
Fortunately there is a explication to the Wep vulnerabilities. The Psk technologies in the form of Wpa and Wpa2 provide a much more accumulate alternative.
