Privacy and Integrity in Multi Wireless Sensor Networks using SafeQ

Wireless Sensor Network deals with both wireless and wired network, which consists of several sensor nodes employed in certain field. Placing the storage node in a network of two tiered sensor, act as an intermediate node between the numerous sensor nodes for storing information and sink for processing the required queries, which is adopted because of the strong power capacity and storage for sensors as well the efficiency of processing the query. In our paper, using SafeQ protocol we provided security mechanism for Multiple Wireless Sensor Network. WSN security in terms of Privacy and Integrity. SafeQ protocol prevents attackers from gaining information from both sensor collected data and sink issued queries. When SafeQ misbehaves, it allows sink to detect undetermined storage nodes. In SafeQ protocol, the privacy is maintained by the technique of encoding both data & query without knowing their actual value & integrity is maintained by the technique of neighborhood chaining that checks for exact data items to satisfy the query results.
