The length of initial value is 24 Bits long with secret key it can be either 40 bits or 104 bits long. WEP uses RC4 Encryption using Stream Ciphers – Steam cyphers are made up of initial value (IV) & secret key.So that Packed is accepted by authenticating the system which leads to unauthorised access to the network. The bits are in the encrypted stream & checksum are modfied by attacker. Integrity Checked Using CRC (Cycle Redundancy Check) – CRC32 is comprimssed by capturing at least two packets.If the encrypted challenge matches AP value, then access is granted. The base station encrypts the challenge with its key responds. Share Key Authentication (SKA) – From here encrypted challenges are requested for access.
Open System Authentication (OSA) – This method grant access to base station authentication requested based on configured policy.WEP provides two types of authentication :.
