Analysis of WPA in 802.11 Wireless Networks for Security

Wireless networking has been experiencing an enormous development in recent years and offers to both network operators and users an attractive flexibility and coverage. But wireless networks are more susceptible to attacks than wired networks. Hence it is visible that some form of security is required to prevent outsiders from exploiting in the form of eavesdropping, hampering the data and authentication denial in wireless networks. To overcome these security challenges, in the existing system Wired Equivalent Privacy (WEP) protocol is used to protect from attacks. But there are several serious security flaws in the protocol due to tools that can automate the cracking of WEP keys lead to a number of practical attacks that WEP fails to achieve its security goals. This paper proposes a secured wireless networks suitable for 802.11 standards using Wireless Protected Access (WPA) based on AES-CCMP (Advanced Encryption Standard-Counter Mode with Cipher Block Chaining Protocol). The result shows that the security issues in wireless networks have been solved.
