WebHow does WEP work for the 802.11 standard? WEP uses RC4 stream cipher to encrypt data between access point and wireless device. WEP uses 8-bit RC4 and operates on 8-bit … WebThe key recovery attacks rely instead on the details of how WEP creates the RC4 key (by concatinating the 3 byte IV with the 5 or 13 byte key), and how RC4 processes that key … WebDec 19, 2024 · The RC4 key for that packet is the IV concatenated with the WEP key. WEP keys have to be changed manually and this typically happens infrequently. An attacker therefore can assume that all the keys used to encrypt packets share a single WEP key. This fact opened up WEP to a series of attacks which proved devastating. fish house frame plans
