Efficient Symmetric and Heterogeneous Mobile Group-Based Key Management Protocol

Wireless Sensor Networks (WSNs) are a newly developed networking technology consisting of multifunctional sensor nodes that are small in size and communicate over short distances. When WSNs applications are used in mobile environments thus new challenges and difficulties are arising. The use of such Mobile wireless sensor networks (MSNs) in sensitive applications such as military or unattended environments is imposing serious security requirements. Many key management solutions have been proposed recently to provide secure communication and reduce the impact of adversaries damaging WSNs. While a few of them were suggested for MSNs. This paper presents a new key management protocol entitled the Efficient Symmetric and Heterogeneous Mobile Group-Based Key Management Protocol (ESAH-MGKM). Evaluation results have shown a significant improvement in terms of resilience against node capture attacks, data confidentiality, energy efficiency, and leaving and joining nodes. Furthermore our scheme supports secure routing through resistance to many routing attacks. Thus, our protocol has a novelty in working with mobile environments and achieved key management and secures routing demands.
