A 128-bit WEP key is usually entered as a string of 26 hexadecimal characters. 26 digits of 4 bits each gives 104 bits; adding the 24-bit IV produces the complete 128-bit WEP key (4 bits × 26 + 24-bit IV = 128-bit WEP key). Most devices also allow the user to enter it as 13 ASCII characters (8 bits × 13 + 24-bit IV = 128-bit WEP key). 152-bit ...
WEP used the RC4 algorithm for encrypting data, creating a unique key for each packet by combining a new Initialization Vector (IV) with a shared key (it has 40 bits of vectored key and 24 bits of random numbers). Decryption involved reversing this process, using the IV and the shared key to generate a key stream and decrypt the payload.
Wireless security. Wireless security is the prevention of unauthorized access or damage to computers or data using wireless networks, which include Wi-Fi networks. The term may also refer to the protection of the wireless network itself from adversaries seeking to damage the confidentiality, integrity, or availability of the network.
RC4 was designed by Ron Rivest of RSA Security in 1987. While it is officially termed "Rivest Cipher 4", the RC acronym is alternatively understood to stand for "Ron's Code" [9] (see also RC2, RC5 and RC6 ). RC4 was initially a trade secret, but in September 1994, a description of it was anonymously posted to the Cypherpunks mailing list. [10]
In cryptography, a pre-shared key (PSK) is a shared secret which was previously shared between the two parties using some secure channel before it needs to be used. Key. To build a key from shared secret, the key derivation function is typically used. Such systems almost always use symmetric key cryptographic algorithms.
IEEE 802.11i-2004, or 802.11i for short, is an amendment to the original IEEE 802.11, implemented as Wi-Fi Protected Access II (WPA2). The draft standard was ratified on 24 June 2004. This standard specifies security mechanisms for wireless networks, replacing the short Authentication and privacy clause of the original standard with a detailed ...
Wireless distribution system. A wireless distribution system ( WDS) is a system enabling the wireless interconnection of access points in an IEEE 802.11 network. It allows a wireless network to be expanded using multiple access points without the traditional requirement for a wired backbone to link them. The notable advantage of WDS over other ...
The WPS push button (center, blue) on a wireless router showing the symbol defined by the Wi-Fi Alliance for this function. Wi-Fi Protected Setup ( WPS) originally, Wi-Fi Simple Config, is a network security standard to create a secure wireless home network . Created by Cisco and introduced in 2006, the point of the protocol is to allow home ...
