Abstract

The present invention relates to a device control and controlled method, device, computer device and storage medium, comprising: generating an original control instruction, obtaining a target controlled device corresponding to the original control instruction, and obtaining the first A globally unique identifier; encrypting the original control instruction according to the first globally unique identifier to obtain an encrypted control instruction; broadcasting the encrypted control instruction through an ultrasonic broadcast signal, so that controlled devices within the receiving range of the ultrasonic broadcast signal receive the encrypted control instruction instruction, the controlled device obtains the local globally unique identifier, and the controlled device whose local globally unique identifier matches the first globally unique identifier decrypts the encrypted control instruction according to the local globally unique identifier to obtain the original control instruction, thereby improving device control and controlled controlled security.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an equipment control and controlled method, device, computer equipment and storage medium. Background technique [0002] With the development of the Internet of Things (IoT, Internet of Things) technology, more and more household electrical appliances, vehicle-mounted devices, etc. have networking capabilities, and people control the operations of these smart devices through the network. [0003] Sending control commands through the network, smart devices can only be controlled by networking, each smart device needs to have network communication capabilities, the cost is high, and the user's big data information during network transmission, such as operation account information and operation instruction information, may be collected, which has the potential to Security risks. Contents of the invention [0004] Based on this, it is necessary to provide a device contro...
