Wireless sensing network security evaluation method and apparatus

Abstract

The invention discloses a wireless sensing network security evaluation method and apparatus. The method mainly comprises the steps of establishing a wireless sensing network security index system, and recording a normal running index value and an attacked index value, in an attacked state, of a first index layer of the wireless sensing network security index system; determining a membership matrix of the first index layer according to the normal running index value and the attacked index of the first index layer and a membership function; determining a membership matrix of an Nth index layer of the wireless sensing network security index system according to a membership matrix and a weight coefficient of an (N-1)th index layer, wherein N is greater than or equal to 2; and determining a maximum membership degree in a membership matrix of a highest index layer as an evaluation result of the wireless sensing network security index system according to a maximum membership principle and an evaluation weight parameter. With the adoption of the method, vulnerabilities in a wireless sensing network can be discovered in time and a basis is provided for adopting a high-quality security technology.

Description

technical field [0001] The invention relates to the technical field of Internet information processing, and in particular to a method and device for evaluating the security of a wireless sensor network. Background technique [0002] Wireless Sensor Networks (WSN, Wireless Sensor Networks) has been applied to environmental monitoring, military observation, health monitoring, intelligent transportation and other fields due to its low power consumption, low cost, distributed and self-organizing characteristics, but due to its resource constraints , The openness of communication, and the network is usually deployed in an unmaintained and uncontrollable environment, which makes it face various threats such as information leakage, information tampering, replay attacks, node capture, and denial of service. Therefore, the security of WSN It is an important prerequisite for its practical application. [0003] Therefore, in order to improve network security and effectively control ne...
