Token authentication method for wireless sensor network based on Restful architecture

Abstract

The invention discloses a token authentication method for a wireless sensor network based on a Restful architecture. The token authentication method comprises the following steps: self organizing a sensor node and a sink node into a network; connecting the sink node to a Web server based on the Restful architecture; and adopting challenge response authentication between the sink node and the Web server, adopting SSL (Security Socket Layer) authentication between the Web server and a client and adopting token authentication between the client and the sink node, wherein the above three authentications are bidirectional authentications, and a user accesses the Web server to acquire data of a wireless sensor node through the client. The token authentication method for the wireless sensor network based on the Restful architecture provided by the invention can effectively prevent a malicious attacker from damaging data, and guarantee the safety of data in the wireless sensor network.

Description

Technical field [0001] The invention relates to the technical field of computer networks, in particular to a wireless sensor network token authentication method based on Restful architecture. Background technique [0002] Wireless Sensor Networks (WirelessSensorNetworks, WSN) is a wireless network composed of a group of tiny sensor nodes in a self-organizing manner. Its purpose is to cooperatively sense, collect and process the information of sensing objects in the geographical area covered by the network, and publish it to observers. . Each sensor in the wireless sensor network has one or more nodes, and the sensor node is usually a miniature embedded system. Each node monitors its own perceptual range objects, monitors specific behaviors, uses nodes to collect data, and transmits the collected data to the nearest sink node, and then enters the convergence stage, and analyzes and analyzes the data collected from the approaching node. Process, and then send the result to the ba...

Problems solved by technology

However, asymmetric encryption schemes require high computation, communication and storage overhead, which determines that it is not feasible to use digital signature and public key certificate mechanisms on resource-constrained sensors.
