Sensor networks are deployed in a hostile environment, security becomes extremely important. An efficient Key Management Scheme to provide security in HSN. In HSN, Clusters are formed as shown in below figure. Routing is done in two phases: 1) Intra-cluster routing each L-sensor sends data to its cluster head(H-Sensor) via multi hops of other L-sensors ; 2)Inter-cluster routing –a cluster head aggregates data from multiple L-sensors and then sends the data to the sink via the H-sensor backbone. This Paper focuses on intra cluster routing using MST (minimum spanning tree) algorithm to approximate the least energy consumption case. After constructing SPT(Spanning tree), every L-sensor node sends sensor information to H-sensor(Cluster head) with in a cluster. In this presents a preventive technique to overcome non- differential side channel attack in HSN by enhancing Elliptic Curve Cryptography and it minimizes storage space requirement, communication overhead and energy consumption in HSN.
