AI Technical Summary

Technical Problem

In existing technologies, the data transmission security between application processors and image processors is insufficient, especially when transmitting sensitive data, which poses a risk of data leakage and tampering, leading to system crashes or user privacy leaks.

Method used

By classifying the data to be transmitted into N categories, and then performing differentiated encryption on each category before transmitting it to the image processor, which then decrypts it, differentiated protection for different types of data is achieved, reducing the impact of encryption and decryption processes on system performance.

Benefits of technology

It improves the security of data transmission between the application processor and the image processor, prevents data leakage and tampering, reduces system consumption, and ensures the correctness and integrity of the data.

Abstract

The application discloses a data transmission control method and related device, which is applied to an electronic device, the electronic device comprises an application processor and an image processor, the method comprises: the application processor acquires to-be-transmitted data; the to-be-transmitted data is classified to obtain N types of data, wherein N is a positive integer; each type of data in the N types of data is encrypted to obtain N types of encrypted data; and the N types of encrypted data are transmitted to the image processor; the image processor receives the N types of encrypted data, and decrypts the N types of encrypted data to obtain the N types of data. By adopting the embodiment of the application, the data transmission security between the application processor and the image processor can be improved.
