Internet of Things access control method and system

Abstract

The embodiment of the invention discloses an Internet of Things access control method and system, which are applied to a central control terminal of the Internet of Things. The method comprise the following steps: sending a first authority query request to a block chain platform according to a received device access operation request sent by an access user; wherein the equipment access operation request comprises an access operation request instruction; receiving a first query result returned by the blockchain platform according to the first permission query request; wherein the first query result comprises an access operation instruction permission set of the access user to the Internet of Things central control terminal; if the access operation instruction to be requested is included inthe access operation instruction permission set, sending an access permission instruction to the access user; and publishing the access record of the access operation of the access user on the centralcontrol terminal of the Internet of Things to the blockchain platform. According to the invention, privacy leakage of the user is further prevented, and normal use of each intelligent device in the Internet of Things is ensured.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to an access control method and system for the Internet of Things. Background technique [0002] The Internet of Things is a ubiquitous network built on the Internet, which integrates a large number of micro-devices such as massive sensors and intelligent processing terminals with the Internet through wired or wireless. With the widespread application and popularization of the Internet of Things, its security and privacy issues have become important issues that need to be broken through. In traditional technologies, the centralized access control strategy of the Internet of Things access control architecture has hidden dangers such as malicious operations by managers, or external users pretending to be authorized users for illegal access, or malicious tampering of the data center of the Internet of Things, which can easily cause users to fail. Privacy is leaked, and th...
