This paper deals with the problems arising in WEP and how we can improve it by using SHA3 in WEP. First part of the paper basically focuses on WLAN, WEP, Encryption and decryption in WEP, Weaknesses of WEP. Second part explains SHA3 (Secure Hash Algorithm-3) and its comparison with earlier versions. Practical work of Paper focuses on performance improvement in WEP by replacing CRC-32 with SHA3, by using perimeters like Packet Delivery Fraction, and End to End Delay.
