Realizing method for internet of things based on trusted operation order remote-control self-control device

Abstract

The invention discloses a realizing method for internet of things based on a trusted operation order remote-control self-control device. The realizing method comprises the following steps: embedding an SD card into a remote self-control device, inserting an encryption card into a server at an operation order control center end of the internet of things, respectively establishing an encryption system at an internet of things operation order control center end and each remote self-control device end by adopting a symmetric cryptographic algorithm, forming a three-dimensional matrix through a secret key seed to establish a combined secret key generating algorithm, generating a symmetric secret key in real time, changing once at a time, encrypting the operation order into a ciphertext through the internet of things operation order control center end encryption system, sending to the remote self-control device end, after performing decryption and integrity verification on the received operation order ciphertext through the remote self-control device encryption system, determining whether to perform relevant operation of the operation order, thereby realizing trusted remote control of the internet of things operation order control center to the remote self-control device.

Description

Technical field: [0001] The invention relates to the field of information security of the Internet of Things in which an operation instruction remotely controls a remote automatic control device. Background technique: [0002] At present, in terms of the application of the Internet of Things, the industrial automation systems of various countries use various PLC operation instructions to control the entire process of industrial automation production, and the operation control of remote automatic control devices is realized by remote operation instructions, of which: remote Automatic control devices such as: satellites, unmanned aerial vehicles, unattended instruments, and automatic control equipment, to realize the control of industrial automation systems and remote automatic control devices, it is necessary for the Internet of Things control center to send operating instructions to the PLC of the industrial automation system, or to The remote automatic control device sends ...

[0002] At present, in terms of the application of the Internet of Things, the industrial automation systems of various countries use various PLC operation instructions to control the entire process of industrial automation production, and the operation control of remote automatic control devices is realized by remote operation instructions, of which: remote Automatic control devices such as: satellites, unmanned aerial vehicles, unattended instruments, and automatic control equipment, to realize the control of industrial automation systems and remote automatic control devices, it is necessary for the Internet of Things control center to send operating instructions to the PLC of the industrial automation system, or to The remote automatic control device sends remote operation instructions. However, the operation instructions of the Internet of Things are sent in plain text, which is easy to be cracked or tampered by hackers, hostile organizations or countries, causing property losses, or causing damage to the country and society. The Internet of Things security technology concept still stays on the PKI technology of the Internet. The signature verification speed of PKI technology is slow, which will greatly affect the efficiency of the command control system. In short, the existing security technology and products cannot meet the needs of the market.
