Lightweight autonomous controllable internet-of-things security access method, terminal and storage medium

Abstract

The invention provides a lightweight autonomous controllable internet-of-things security access method, a terminal and a storage medium, and the method comprises the steps: S1, enabling a to-be-accessed device to request to access a terminal intranet, carrying out the multi-factor identity authentication of the to-be-accessed device through a network access authentication module, and carrying out the network access authentication; s2, after the access equipment is successfully authenticated, the encryption chip creates a thread pool; s3, before data interaction, a sent data message is subjected to national cryptographic algorithm block encryption operation through a sub-thread in a thread pool, so that the capability of an access terminal for resisting active attacks and passive attacks is enhanced; and S4, a fixed frame header and a fixed frame tail are added to the data message subjected to packet encryption through the interactive gateway, then the data message is sent to a bidirectional FIFO isolation assembly, decryption is performed after fixed frame header matching and fixed frame tail integrity verification, and data security interaction is performed after the access device accesses the terminal intranet. According to the invention, the security and privacy of data transmission can be ensured, and the capability of resisting active and passive attacks is improved.

Description

technical field [0001] The invention belongs to the technical field of the Industrial Internet of Things, and in particular relates to a lightweight, autonomously controllable Internet of Things security access method, a terminal and a storage medium. Background technique [0002] With the concept of "Industry 4.0", industrial interconnection is being gradually realized. Industrial Connectivity means that organizations can connect multiple disparate devices, including legacy equipment, and have them "talk" to each other. By collecting, analyzing and leveraging data from new and legacy equipment, organizations can increase efficiency and gain a competitive advantage. [0003] In the existing technology, the privacy and security requirements of data transmission in the industrial interconnection are relatively high. If important data parameters are leaked, it will cause huge irreparable losses to the entire industrial control system. For example, the patent whose authorized ...
