Secure Level Transmission in Wi-Fi Using Cryptography

Wi-Fi is a mechanism that allows electronic devices to exchange data wirelessly over a computer network Wi-Fi suggests Wireless Fidelity, resembling the long-established audio-equipment classification term Hi-Fi or High Fidelity. This paper first gives some background information about Wi-Fi system and security issues in ad hoc networks, and then it concentrates on the specific security measures like hybrid encryption techniques using both AES and RSA algorithms and also the different standards. To provide the security for the data transmitted through Wi-Fi, it uses WEP algorithm, WEP64 and WEP128 and then it moves to WPA (Wi-Fi Protected Access) as the key is short in WEP.
