	Wired Equivalent Privacy - Wikipedia, the free encyclopedia
		WEP was intended to provide comparable confidentiality to a traditional wired network, hence the name.
		WEP is part of the IEEE 802.11 standard ratified in September 1999.
		WEP uses the stream cipher RC4 (Rivest Cipher) for confidentiality and the CRC-32 checksum for integrity.

	(In)Security of the WEP algorithm
		A secondary function of WEP is to prevent unauthorized access to a wireless network; this function is not an explicit goal in the 802.11 standard, but it is frequently considered to be a feature of WEP.
		WEP relies on a secret key that is shared between a mobile station (eg.
		WEP uses the RC4 encryption algorithm, which is known as a stream cipher.

	Encyclopedia: Wired Equivalent Privacy
		WEP is designed to provide the same level of security as that of a wired LAN.
		WEP aims to provide security by encrypting data over radio waves so that it is protected as it is transmitted from one end point to another.
		WEP is used at the two lowest layers of the OSI model - the data link and physical layers; it therefore does not offer end-to-end security.

		WEP algorithm is part of the 802.11 Standard that describes communication in WLANs.
		WEP relies on a secret key shared between a laptop with wireless Ethernet card (or mobile station) and an access point (the base station).
		WEP encryption uses the RC4 encryption method and the conversion of plain text, cipher text and the initialization vector (IV) that is used to turn the plain text into cipher text.

		WEP is used to encrypt and decrypt data signals that transmit between WLAN devices.
		WEP Keys must be comprised of the hexadecimal characters and must contain 10 characters for 40-bit WEP Keys or 26 characters for 128-bit WEP keys.
		The WEP key that you use to transmit data must be set to the same value on your Workgroup Bridge and other devices with which it communicates.

	Wired Equivalent Privacy (WEP) (Site not responding. Last check: 2007-10-22)
		The Wired Equivalent Privacy (WEP) algorithm is used to protect wireless communication from eavesdropping, because wireless transmissions are easier to intercept than transmissions over wired networks, and wireless is a shared medium, everything that is transmitted or received over a wireless network can be intercepted.
		WEP key (secret key) are available in two types, 64-bits and 128-bits.
		The reson for this misnomer is that the WEP key (40/104 bits) is concatenated with the initialisation vector (24 bits) resulting in a 64/128 bit total key size.

	WEP Overview
		Wired Equivalent Privacy (WEP) is a security protocol, specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11b, that is designed to provide a wireless local area network (WLAN) with a level of security and privacy comparable to what is usually expected of a wired LAN.
		A wired local area network (LAN) is generally protected by physical security mechanisms (controlled access to a building, for example) that are effective for a controlled physical environment, but may be ineffective for WLANs because radio waves are not necessarily bound by the walls containing the network.
		WEP seeks to establish similar protection to that offered by the wired network's physical security measures by encrypting data transmitted over the WLAN.

	Wireless Glossary: Wired Equivalent Privacy (WEP)
		Now widely recognized as flawed, WEP was a data encryption method used to protect the transmission between 802.11 wireless clients and APs.
		WEP's problems are well-known, including an insufficient key length and no automated method for distributing the keys.
		WEP can be easily cracked in a couple of hours with off-the-shelf tools.

	WEP Security Issues
		The Wired Equivalent Privacy protocol was designed to be the cryptographic technology used to protect data at the link-level during wireless transmission.
		The “key” to WEP encryption is a shared secret key “sk” that must be known to the device at each end of the wireless transmission.
		WEP security may have been doomed from the outset as it was designed to provide security with minimal overhead given the restrictions on wireless bandwidth at the time.

	802.11 Encryption with Wired Equivalent Privacy (WEP)
		Unlike a wired network where a physical connection is required, anyone within range of a wireless AP can conceivably send and receive frames as well as listen for other frames being sent.
		Wired Equivalent Privacy (WEP) is defined by the IEEE 802.11 standard and is intended to provide a level of data confidentiality that is equivalent to a wired network.
		WEP encryption for an 802.11 frame is indicated by setting a WEP flag in the MAC header of the 802.11 frame.

	802.11 WEP: Concepts and Vulnerability
		WEP inputs the resulting "seed" into a pseudo-random number generator that produces a keystream equal to the length of the frame's payload plus a 32-bit integrity check value (ICV).
		WEP is vulnerable because of relatively short IVs and keys that remain static.
		WEP does a good job of keeping most people out, at least those that are honest.

		WEP has received an enormous amount of attention in the media as being flawed and broken.
		As its name implies, WEP was only intended to give wireless users the level of security implied on a wired network (which isn't much).
		WEP was not designed to be the end-all, be-all security solution for wireless networks and, as we shall see, WEP has a number of shortcomings, which make it vulnerable to several classes of attacks.

	What is WEP (Wired Equivalent Privacy)?
		Wired Equivalent Privacy (WEP) is the encryption algorithm built into the 802.11 (Wi-Fi) standard.
		WEP encryption uses the RC4 stream cipher with 40 or 104 bit keys and a 24 bit initialization vector.
		WEP has the same problem as all systems based upon shared keys: any secret held by more than one person soon becomes public knowledge.

	What is WEP Encryption for Wireless Network?
		Wired Equivalent Privacy (WEP) is a security protocol for wireless networks that encrypts transmitted data.

	Wireless LAN Security
		WEP (Wired Equivalent Privacy), the encryption protocol used by all WiFi 802.11b devices to secure the wireless network is at best implemented half the time.
		It was suppose to give wireless networks the equivalent privacy of wired networks by using 40 and 104 bit encryption.
		Attempting to manually change the WEP key is highly impractical due to the fact it requires you to manually communicate to every wireless user what the new WEP key is so that they can manually enter it in to their WEP settings.

		Yes, it provides privacy equivalent to the privacy you had on your wired LAN, as long as that LAN had no privacy whatsoever.
		Privacy (encryption) services are commonly linked to authentication such that unique per-session keys are distributed at the time of authentication.

		WLAN privacy is normally enforced through some type of data-stream encryption, usually in the form of WEP (Wired Equivalent Privacy).
		WEP uses either a 40-bit or a 128-bit RC4 encryption mechanism, typically implemented in the NIC's hardware to minimize performance degradation.
		WEP was designed to provide the security equivalent to a wired LAN and was not originally envisioned as a bullet-proof security architecture.

		WEP was designed to provide confidentiality for 802.11 networks, similar to that of wired networks.
		Unfortunately, analysis performed by researchers at Intel [ZIP], Berkeley [FAQ], University of Maryland [PDF] and elsewhere has shown WEP to be fundamentally flawed.
		Because WEP uses RC4 encryption, this is enough information to derive the RC4 keystream—the stream of bits XORed with plaintext to generate ciphertext.

	Why is WEP crackable? How WEP weaknesses affect your wireless network security
		The 802.11 designers intention was to provide wireless users with a level of security equivalent to that achievable on a wired network.
		This is good in that it reduces the chances of a hacker capturing weak keys, but also has the effect of reducing the already limited key possibilities further, increasing the chance of reuse of keys.
		WEP does have a message integrity check but hackers can change messages and recompute a new value to match.

		The IEEE 802.11 standard defines the use of Wired Equivalent Privacy (WEP), which relies on pre-shared keys for access control and privacy.
		The keys are indexed, and when encrypted data is transmitted, the index is referenced, indicating which key should be used by the receiving device to decrypt it.
		As you can see, WEP keys are similar to passwords, except they are lengthy hexadecimal numbers, which makes them more difficult to remember.
