The continuous demand of wireless sensor networks to operate critical and sensitive environmental, healthcare and industrial data raised the need for effective security mechanisms. However, the inherent energy constraints in the sensor nodes pose different challenges in the security of wireless sensor networks. Many researchers have studied the energy consumption required by these sensor nodes through applying different security schemes. In this paper, we estimate the communication energy consumption for homogeneous wireless sensor security using DH-EKE public key agreement scheme in terms of variable key sizes and neighbor nodes. The evaluation results demonstrated that the energy consumption of DH-EKE ranges from 4.8 μj for 8-bit key size and one neighbor node to 1538 μj (1.6 mj) for 256-bit key size and 10 neighbor nodes Hence, the proposed work will help the low power cryptographic system designers to be exposed for larger alterable schemes with variable techniques.
