Wireless is a growing area in research and industry. Wired Equivalent Privacy (WEP) or the 802.11b is the most spread standard. It is designed to provide a same security as that of the wired LAN. Wirelesses Local Area Networks (WLANs) have become more prevalent and are widely deployed and used in many popular places like university campuses, airports, residences, cafes etc. With this growing popularity, the security of wireless network is also very important. In this paper, the evaluation of CRC-32 and SHA-1 is performed by calculating the throughput and by running dictionary attack on both the algorithms. The analysis shows that SHA-1 is more secure that CRC-32.
