Abstract: Along with the in-depth application of sensor networks, the security issues have gradually become the bottleneck of wireless sensor applications. To provide a solution for security scheme is a common concern not only of researchers but also of providers, integrators and users of wireless sensor networks. Based on this demand, this paper focuses on the research of strengthening the security of cluster-based wireless sensor networks. Based on the systematic analysis of the clustering protocol and its security enhancement scheme, the paper introduces the broadcast authentication scheme, and proposes an SA-LEACH network security enhancement protocol. The performance analysis and simulation experiments prove that the protocol consumes less energy with the same security requirements, and when the base station is comparatively far from the network deployment area, it is more advantageous in terms of energy consumption and t more suitable for wireless sensor networks.

 

Keywords: Wireless sensor network, Cluster-based communication protocol, Security, Key.
