Abstract

The invention relates to a hierarchical access control method for the Internet of Things, and belongs to the field of resource access control of the Internet of Things. The method comprises the following steps: constructing an Internet of Things equipment cluster by adopting an improved K-means algorithm; determining an association relationship between the cluster head equipment and the gateway node by adopting a matching algorithm; constructing a global block chain network by the gateway node; constructing a local block chain network by the cluster head device; sending access request information to the associated cluster head device by the source device, wherein the cluster head device judges an access type; if the access is the intra-domain access, calculating a trust value of the source equipment, and judging the credibility of the source equipment; if the source device is credible, calling a local block chain contract, obtaining target device data, and sending the target device data to the source device; if not, the cluster head device rejecting the access request of the source device; if the access is inter-domain access, the cluster head device forwarding access request information to a gateway node; the gateway node judging the credibility of the source equipment; if the source device is credible, calling a global block chain contract, obtaining target device data, and sending the target device data to the source device; and if not, the cluster head device denying the access request.

Description

technical field [0001] The invention belongs to the technical field of resource access control of the Internet of Things, and relates to a layered access control method of the Internet of Things. Background technique [0002] The rapid development of the Internet of Things technology has brought about a huge digital transformation, which is profoundly changing the traditional industrial form and people's production and lifestyle. It is estimated that by the end of 2025, the number of global IoT devices will reach 41.6 billion. The diversification of Internet of Things applications has changed the fields of industrial manufacturing and smart life, and it has also brought security risks. The Internet of Things generates massive amounts of data, including a large amount of personal privacy and security information. Once leaked, it will bring great losses to users. Identity authentication and access control to resources and services are the main ways to protect the security an...
