An Encryption Scheme Based on Elliptic Curves in Wireless Sensor Networks

Key management is one of the most important part of wilrelss sensor networks.Resently,it receives widespread attention,many key distribution schemes have been proposed.Given the pover constrait of sensor nodes,the proposed scheme should reduce the energy consuming mostly.Thus,this paper proposes an encryption scheme based on elliptic curves in wireless sensor networks,in this scheme,the raw key chain and key updating are computed in base station,and greatly reduces the energy consuming.
