Embodiment Construction

[0052] On the basis of the above description, in order to make the purpose, advantages and technical solutions of the present invention more clear, the present invention will be further elaborated below in conjunction with an example and the accompanying drawings, but this embodiment does not constitute any limitation to the present invention.

[0053] figure 1 Describes the general flow of IoT smart devices processing control commands and introduces the possible impact on the flow of original device control commands after using the dynamic loading function to load malicious modules.

[0054] In the traditional control command processing flow, when the smart device system receives a remote control command, it will trigger a hardware exception and notify the system that the receiving device (Wifi module, serial port, etc.) has data coming. At this time, the scheduler will directly interrupt the current operation. The task, and turn to the corresponding exception processing meth...

Abstract

The invention relates to a system-grade safety protection method for a control instruction of intelligent equipment. The system-grade safety protection method comprises the following steps: firstly, deploying a software system environment for safe operation of the control instruction of the intelligent equipment, establishing a safety area for storing sensitive data structures and methods and a non-safe environment for executing normal operation such as control instruction analysis and dynamic module loading by using a hardware isolation module based on MPU; secondly, deploying important data structures and methods of the control instructions inside the safety area, and designing a processing frame for the control instruction; finally, designing related procedures for safely processing the control instruction with the combination of the important data structures and methods in the safety area, and ensuring completeness and safety of the control instruction in the transmission and analysis process. By adoption of the system-grade safety protection method, a reliable safe isolation environment can be provided for intelligent equipment in a system layer, and control instruction transmission safety in a system is ensured.

Description

technical field [0001] The invention belongs to the field of system security in information security, and specifically relates to a system-level control command protection method, which ensures that control commands entering smart devices will not Subject to tampering due to the presence of malicious tasks. Background technique [0002] A smart device is a comprehensive product with hardware (mechanical, sensing), intelligence and connection capabilities. It is an extension of hardware functions from the local to the Internet. The interconnection function also enables some functions of the device to be realized outside the device, that is, the cloud. It enables users to remotely control smart devices, which greatly expands the application scenarios of smart devices. Compared with smart terminals (such as smart phones), smart devices have relatively low computing power and relatively weak hardware configuration. However, with the overall development of the smart device indus...
