A priority-based data security communication method for ipv6 heterogeneous sensor networks

Abstract

The invention provides a priority-based IPV6 heterogeneous sensor network data security communication method. Multimedia sensor nodes and scalar sensor nodes supporting the IPV6 protocol stack form a heterogeneous network, transmitted data are classified according to the importance and priority in different application environments, and the balance between data security transmission and network service quality is achieved through different encryption levels. The method can be applied to the field of airport public security control. According to the method, the data is distinguished according to the priority; compared with that all data are transmitted according to the uniform standard, the method has the advantages that the network service quality is considered fully, and energy consumption is reduced to the certain extent; partial privacy conversion and encryption transmission with importance distinguish are performed on the acquired data, the security is guaranteed, and the computation overhead and network load are reduced as compared with those of full encryption.

Description

Technical field [0001] The invention relates to a priority-based IPV6 heterogeneous sensor network data security communication method, which belongs to the cross field of information security and IPV6 wireless sensor network technology. Background technique [0002] Wireless Sensor Networks (Wireless Sensor Networks, WSN) is a multidisciplinary research field that has attracted much attention in today's society. It will play an indispensable role in all aspects of human life in the future and promote the process of modern society. Provide people with the most timely, effective and truthful information. With the increasing maturity and popularity of the Internet of Things and wireless sensor network applications, single-structure sensing networks can no longer meet people's needs, especially in the fields of public safety monitoring, smart home, smart transportation, and smart medical care. Scalar information such as humidity and brightness are collected at the same time as image...

Problems solved by technology

[0003] However, taking the public safety monitoring application at the airport as an example, the temperature information data collected by the high temperature alarm sensor node is very small, only a dozen bytes, while the video sensor node responsible for monitoring whether someone is stealing or tracking the flow of dangerous goods is responsible for collecting For image and video information, the size of the image may be tens of K, while the video information may be hundreds of K or even M, and the safe transmission of these data needs to be guaranteed regardless of their size
