Abstract

The invention provides a data access method, system and device applied to the Internet of Things, and aims to reduce the computation overhead of a sensing node on the basis of ensuring the data security of the accessed sensing node. The data access method applied to the Internet of Things is applied to sensing node management equipment and comprises the steps of receiving a reputation authentication request , wherein the reputation authentication request is sent by the sensing node after receiving an access request from a user and at least carries a user identifier of the user; sending the reputation authentication request to a reputation center device; receiving a reputation response returned by the reputation center device, wherein the reputation response at least carries a first reputation value of the user; and verifying whether the user has the permission to access the sensing node according to the first reputation value, and sending authorization information to the user or the sensing node when verifying that the user has the permission to access the sensing node, so as to allow the user to access the sensing node.

Description

technical field [0001] The present invention relates to the technical field of Internet of Things security, in particular to a data access method, system and equipment applied to the Internet of Things. Background technique [0002] The Internet of Things (IoT) is a new type of network that uses a variety of communication technologies to interconnect a large number of sensing nodes. These sensing nodes form the sensing layer in the IoT architecture, collect data from different environments, process the data, and hand over the data to devices at other levels in the IoT architecture for processing. IoT has notable applications in multiple domains such as healthcare, transportation, and manufacturing, etc., playing an important role in the current digital life. [0003] At present, the security issues in the IoT environment still need to be fully considered, especially how to safely use the data collected by the sensing nodes. In the Internet of Things, the perception layer n...
