New low-energy security routing protocol for wireless sensor network based on SPINS

Low-Energy Adaptive Clustering Hierarchy (LEACH) protocol is a critical clustering hierarchy routing protocol for wireless sensor network.Lack of security measures makes it vulnerable to personation and laptop attacks,especially during the cluster set-up phase.A new low-energy secure routing protocol based on SPINS was proposed.It authenticated broadcast packets using μTESLA,distributed authenticated key to cluster-head and cluster-members using SNEP.In the proposed protocol,sensor nodes needed to verify whether the cluster-head was the node it claimed to be.They also needed to verify whether they could reach the cluster-head.If both checks were passed,then sensor nodes joined in the cluster.Security analysis shows that the proposed protocol realized confidentiality,integrity,freshness,identity authentication,two-way authentication and some other security objectives.Simulation results based on NS2 show that energy consumption of sensor nodes does not significantly increase,due to the sink node and cluster-heads undertaking most of safety related tasks.
