Problems solved by technology

[0002] For inter-process communication, security must be considered. The data in the communication can only be read and written by the processes of the sending and receiving parties, and other processes cannot access it.
However, there is no MMU (Memory Manage Unit, memory management unit) on the hardware of the MCU (Microcontroller Unit, microcontroller) running the embedded operating system, and the natural isolation of memory when inter-process communication cannot be carried out. How to achieve safe communication between processes is only a matter of For access during communication between the sending and receiving parties, and to protect other processes from illegal access, further solutions are still needed

Abstract

The embodiment of the invention provides an inter-process communication method, a device, electronic equipment and a computer readable storage medium, and relates to the field of process communication. The method comprises the steps that information of at least one shared access area is acquired, a data interaction message is sent to a target process through a current process, and the data interaction message at least comprises information of all the shared access areas so that the current process and the target process can conduct data interaction based on any shared access area. According tothe method, the information of at least one shared access area pre-registered to the memory protection unit is acquired, and the data interaction message containing the information of the shared access area is sent to the target process, so that at least two processes perform data interaction by accessing the registered memory space; therefore, the process except the interactive process cannot access the shared access area, and safe communication between the processes is realized.

Description

technical field [0001] The present application relates to the technical field of inter-process communication, and specifically, the present application relates to an inter-process communication method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] For inter-process communication, security must be considered. The data in the communication can only be read and written by the processes of the sending and receiving parties, and other processes cannot access it. However, there is no MMU (Memory Manage Unit, memory management unit) on the hardware of the MCU (Microcontroller Unit, microcontroller) running the embedded operating system, and the natural isolation of memory when inter-process communication cannot be carried out. How to achieve safe communication between processes is only a matter of It is used for access during communication between the sending and receiving parties, and to protect other processes from illegal acces...
