An enhanced key management using ZigBee Pro for wireless sensor networks

In this paper, we propose an enhanced key management mechanism using ECDH(Elliptic Curve Diffie-Hellman) and subMAC for wireless sensor networks using ZigBee. ZigBee consumes low power and provides security in wireless sensor networks. ZigBee Pro enhances security and supports a large number of applications. Despite enhanced security, ZigBee Pro has vulnerabilities of key management, i.e., weakness of key distribution. We use ECDH for secure key...
