Improved matrix based Key Management Scheme for Wireless Sensor Network security

Wireless Sensor Network (WSN) consists of a large amount of sensor nodes fitted with restricted memory and computing capacities that have been powered by batteries. These contained sensors face several threats to safety and therefore some cryptographic mechanism is needed for secure communication. In WSNs, key management is a working research subject. In this paper, we have proposed a Lightweight Matrix based key management scheme for WSN. Our proposed key management system used encryption method to enhance storage space and node to become lightweight and nodes connectivity. We assessed our scheme and it is shown that our proposed scheme provide better connectivity and storage space for the network.
