Implementation of Privacy Protection of Wireless Data using AES

Now a day’s, wi-fi networks are widely used in university data programs, along with banking and military applications such as battlefield surveillance such networks are used in many industrial and consumer applications, such as industrial process monitoring and control, machine health monitoring, and so on. Wireless networks are greater liable to eavesdropping, change, impersonation and replaying attacks than the wired networks. A lot of work has been done to secure wireless networks. The existing solutions can protect the user data during transmission, but cannot stop the inside attack where the administrator of the user database reveals the sensitive user data. Our proposed system is practical approach to prevent the inside attack by using multiple data servers to store user data. Moreover securely distributing the user data in multiple data servers and employing the Advanced Encryption Standard to perform statistical analysis on the user data without compromising the user privacy, is the another major factor of concern.
