BIST Based Secure Data Aggregation in Wireless Sensor Network

Number of applications, like border surveillance, under water sensor networks widely use the Wireless Sensor Network. When in network data aggregation is performed there is significant reduction in the amount of communication overhead and energy consumption in a large WSN. Various types available for data aggregation techniques are centralised approach, In-network aggregation, tree-based approach, Cluster-based approach, Different protocol which performs secured data aggregation considered are Secure Data Aggregation Protocol (SDAP), Secure information aggregation (SIA), Threshold security for Information aggregation in Sensor networks (THIS), Privacy-preserving Data Aggregation (PDA), Secure Encrypted-data Aggregation (SEA), Data aggregation and authentication protocol (DAA). However in all these approaches the protocol do not allow intermediate nodes to perform data aggregation thus limits the benefit of data aggregation. In this paper the new approach i. e. BIST+RC6+Aggregation is considered which will perform secured data aggregation
