Distributed control method for information of accessing internet of things by user

Abstract

The invention provides a distributed control method for information of accessing an internet of things by a user, relating to the technical field of communication. The user applies to access a network resource to an access control server, the access control service issues an access certificate to the user and records relevant information of the user. The user forwards the access certificate to a wireless sensor node through a network management center of a wireless sensor network; and the user initiates an access request to the network management center, the network management center carries out access control on the user, the wireless sensor node carries out permission restriction on the user, and an access response message is sent to the user by adopting a safety manner. In addition, the user grants partial permissions or all permissions of the user for another legal user through permission authorization. The distributed control method disclosed by the invention can realize effective restriction and permission management of accessing the wireless sensor network by the user, and has the characteristics of low overhead of the node, and the like.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a distributed control method for Internet of Things information. Background technique [0002] The wireless sensor network is different from the general wireless network. Its characteristics are: extremely limited energy, huge amount of sensing data, limited communication capability, huge number of nodes, limited computing power and storage capacity, and difficult network maintenance. [0003] Wireless sensor networks mainly collect environmental data and provide users with data services of environmental information. With the deepening of applications and the diversification of sensing data, the environmental data sensed by sensors will contain a large amount of sensitive and private data. How to effectively protect these data from being accessed by illegal users and control the user's access behavior for Providing users with limited access services is one of the main pro...

AI Technical Summary

Problems solved by technology

[0015] The present invention aims at the disadvantages of the existing access control mechanism of the wireless sensor network that users are completely controlled by nodes, the control security intensity is low, the user only visits one node at a time, the efficiency is low, and the authority management is inefficient, etc., combined with the security features of the wireless sensor network , a distributed access control method combining symmetric encryption mechanism and asymmetric encryption mechanism is proposed to restrict and manage legitimate users' access to key resources of sensor networks, and ensure the security of key resources
