WEP Wired Equivalent Privacy

Wired Equivalent Privacy (WEP) is the encryption algorithm built into the 802.11 (Wi-Fi) standard. WEP encryption uses theRC4 circulate cipher with forty or 104 bit keys and a 24 bit initialization vector.
WEP Key Generation

Most 802.11 gadgets permit WEP keys to be entered the utilization of an ASCII passphrase or in hexidecimal format. The conversion between these two codecs is an trade standard which is shared via nearly all suppliers of 802.11 gear.

Some 802.11 units have issue the utilization of ASCII passphrases or use a non-standard conversion algorithm. For those units, you will want to use the hexadecimal version of your WEP key.

Powerdog Industries offers a WEP De Facto Key Generator on their internet sit downe. The key generator will convert a WEP passphrase to its 40-bit or 104-bit hexadecimal equivalent.

WEP Security Issues

WEP has led a afflicted existence due to many security issues. The safety concerns with Wired Equivalent Privacy (WEP) include:

    A high proportion of wi-fi webworks have WEP disabled as a result of the administrative overhead of maintaining a shared WEP key.
    WEP has the identical problem as all programs primarily based upon shared keys: any secret held through multiple individual soon turn intos public information. Take as an instance an worker who departs a company – they nonetheless know the shared WEP key. The ex-employee may take a seat outdoor the corporate with an 802.11 NIC and sniff webwork visitors and even attack the interior network.
    The initialization vector that seeds the WEP algorithm is shipped in the clear.
    The WEP checksum is linear and predictable.

The number and scope of difficulties with WEP safety have led to the advent of WPA (Wireless Protected Access).

WEP Security Tools
AirSnort

AirSnort is a wireless LAN (WLAN) device which cracks encryption keys on 802.11 WEP webworks. AirSnort operates by passively screening transmissions and computing the WEP encryption key when enough packets had been gathered.
BSD-Airtools

bsd-airtools is a package deal that offers a complete deviceset for wireless 802.11 auditing. Namely, it at the moment comprises a bsd-based Wired Equivalent Privacy (WEP) cracking software, known as dweputils (as well as kernel patches for NetBSD, OpenBSD, and FreeBSD). It additionally accommodates a curses based totally ap realizeion application similar to internetstumbler (dstumbler) that can be utilized to detect wireless access factors and connected nodes, view signal to noise graphs, and interactively scroll through scanned aps and examine records for every. It also includes a couple other instruments to supply a whole instrumentset for using all 14 of the prism2 debug modes as neatly as do general analysis of the hardware-based link-layer protocols supplied by way of prism2s display debug mode.
WEPCrack

WEPCrack is a device that cracks 802.11 WEP encryption keys by way of exploiting the weaknesses of RC4key scheduling.
WAP Attack

WepAttack is a WLAN open source Linux instrument for breaking 802.11 Wired Equivalent Privacy (WEP) keys. This instrument is in preserving with an lively dictionary assault that checks hundreds of thousands of phrases to search out the proper key. Only one packet is required to start an attack on WEP.
WEPWedgie

WEPWedgie is a devicekit for figuring out 802.11 WEP keystreams and injecting traffic with known keystreams. The softwarekit additionally embodys good judgment for firewall rule mapping, pingscanning, and portscanning by implys of the injection channel and a cell modem.
