Wireless Sensor Network Security Management System

Abstract

The invention provides a wireless sensor network safety management system. The proper safety service is dynamically combined according to the safe service requirements and the communication environment so that a network is in a dynamic safety state at different levels, the energy waste and the inflexibility caused by the static safety in the safety protection are overcome, simultaneously, the safety management system adopts a distributive structure, and the energy consumption problem caused by the communication of an integrative middle base station and a node is solved. The safety management system is realized by adopting a crossing layer safety management system, the system structure comprises five assemblies: safety agents, safety decisions, safety protocols, data assemblies and resource libraries, wherein the safety agents obtain various parameter values through the interaction between a definition interface and each layer, the parameter values are analyzed for deciding the safety combination protocols meeting the requirements by the safety decisions, the corresponding safety protocols are activated through the safety combination protocols, the data assemblies store conditions of safety service capable of being provided by the safety protocols and are used for realizing the safety decisions, and the resource libraries are used for storing cost parameters consumed during the safety protocol operation.

Description

technical field [0001] The invention belongs to the field of network security technology and service computing, and relates to a security management system in a wireless sensor network, which uses security as a service and dynamically combines security services according to security service requirements and communication environments, thereby proposing an adaptive Wireless sensor network security management system. Background technique [0002] With the development of sensor network applications, its security issues have attracted more and more attention. Starting from the application of sensor networks, there are different security service requirements for different application requests. However, in the existing sensor networks, security measures are unified. Yes, that is, for different applications, the security protection provided by the network is the same and maintained at a static security level, which will result in: 1. Some applications may not require very high secu...
