Encryption chip fault recovery method and system, electronic equipment and storage medium

Abstract

The invention discloses an encryption chip fault recovery method and system, electronic equipment and a computer readable storage medium, and the method comprises the steps: when an encryption chip does not respond to a command of a main control chip, controlling a handle of SPI equipment corresponding to the encryption chip to be closed, and unloading a driver of the SPI equipment; pulling down a power supply control port of the encryption chip, controlling the encryption chip to be powered off, and controlling the encryption chip to be powered on after a preset time is delayed; and loading a driver of the SPI equipment, and controlling the handle to open. According to the encryption chip fault recovery method, whether the encryption chip is abnormal or not is automatically detected through software, when the encryption chip is abnormal, fault recovery is conducted in the mode of reloading the driver and restarting the SPI equipment handle, rapid recovery can be achieved, the encryption function can be recovered without restarting, and therefore the reliability and integrity of uploaded data are guaranteed, and the stability and reliability of the system are improved.

Description

technical field [0001] The present application relates to the technical field of TBOX, and more specifically, relates to an encryption chip failure recovery method and system, an electronic device, and a computer-readable storage medium. Background technique [0002] With the introduction of the China VI standard, the new standard stipulates that the data uploaded to the platform must be encrypted by SM2. If the encryption chip fails to work, it will result in the inability to upload valid data. Therefore, the stable operation of the encryption chip is very important. [0003] TBOX (full name in English: Telematics BOX) is unavoidable in the process of use due to the unstable power supply of the car, static electricity, interference and other reasons, as well as the instability and crash of the encryption chip itself, resulting in abnormal operation of the encryption chip and the inability to encrypt data. . At this time, to restore the encryption chip, the system must be ...

Problems solved by technology

[0003] TBOX (full name in English: Telematics BOX) is unavoidable in the process of use due to the unstable power supply of the car, static electricity, interference and other reasons, as well as the instability and crash of the encryption chip itself, resulting in abnormal operation of the encryption chip and the inability to encrypt data.

At this time, to restore the encryption chip, the system must be restarted, but it takes a long time to restart the system, which will inevitably cause data loss and affect data security and user experience.
