WEP was included as the privacy component of the original IEEE 802.11 [8] standard ratified in 1997. [9] [10] WEP uses the stream cipher RC4 for confidentiality, [11] and the CRC-32 checksum for integrity. [12] It was deprecated in 2004 and is documented in the current standard. [13] Basic WEP encryption: RC4 keystream XORed with plaintext
WEP used a 64-bit or 128-bit encryption key that must be manually entered on wireless access points and devices and does not change. TKIP employs a per-packet key, meaning that it dynamically generates a new 128-bit key for each packet and thus prevents the types of attacks that compromised WEP.
The main purpose to implement TKIP was that the algorithm should be implementable within the capabilities of most of the old devices supporting only WEP. The initial authentication process is carried out either using a pre-shared key (PSK), or following an EAP exchange through 802.1X (known as EAPOL , which requires the presence of an ...
Wireless security is another aspect of computer security. Organizations may be particularly vulnerable to security breaches [6] caused by rogue access points.. If an employee adds a wireless interface to an unsecured port of a system, they may create a breach in network security that would allow access to confidential materials.
Temporal Key Integrity Protocol (TKIP / t iː ˈ k ɪ p /) is a security protocol used in the IEEE 802.11 wireless networking standard. TKIP was designed by the IEEE 802.11i task group and the Wi-Fi Alliance as an interim solution to replace WEP without requiring the replacement of legacy hardware.
Wi-Fi Protected Access (WPA) better than WEP, a 'pre-standard' partial version of 802.11i 802.11i a.k.a. WPA2, uses AES and other improvements on WEP A5/1 and A5/2 cell phone encryption for GSM

WEP is a deprecated algorithm to secure IEEE 802.11 wireless networks. Wireless networks broadcast messages using radio, so are more susceptible to eavesdropping than wired networks. When introduced in 1999, WEP was intended to provide confidentiality comparable to that of a traditional wired network.
