Abstract: Based on the existing dynamically updated key management scheme on Wireless Sensor Network(WSN), this paper improves its flaw of no identity authentication and weak scalability by adding identity authentication modules and proposes a new key management scheme and a feasible new node joining mechanism on WSN. Compared with the original one and similar key management schemes, this scheme maintains efficiency while ensuring higher security and bringing in better scalability, network connectivity and other features.
