Embodiment Construction

[0046] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0047] refer to figure 1 , usually key key information is stored in the solid-state drive controller Efuse. The SSD controller Bootrom has two modes, namely loading mode and downloading mode, and different modes can be selected through external GPIO configuration. After the solid-state hard disk leaves the factory, the solid-state hard disk controller Bootrom works in the loading mode. At this time, the controller loads the Bootloader ciphertext file from the Flash, uses the key in Efuse to decrypt the ciphertext bootloader, and generates the plaintext bootloader to run. ...

Abstract

The present application relates to an Efuse-based key reading control method, device, computer equipment and storage medium, wherein the method includes: obtaining an Efuse-based key reading request; according to the Efuse-based key reading request through The controller runs the key reading program; judges whether the controller is in the loading state; if the controller is in the loading state, reads the key in the Efuse; if the controller is not in the loading state, prohibits reading Get the key in the Efuse. The present invention can read the secret key from Efuse only when the controller is running in the loading mode, and when the controller is running in the download mode, the code cannot read the secret key from Efuse, which realizes the improvement of the secret key stored in Efuse safety.

Description

technical field [0001] The invention relates to the technical field of solid-state hard disks, in particular to an Efuse-based key reading control method, device, computer equipment and storage medium. Background technique [0002] Efuse is similar to EEPROM, which is a one-time programmable memory, and information will be written before the chip leaves the factory. Efuse can usually be used to store the repair data of MEM repair, and can also be used to store chip information: such as the chip can use the power supply voltage, chip version number, production date. Efuse usually contains chip voltage field, chip version number, chip production date and key key information. The SSD controller Bootrom has two modes, namely loading mode and downloading mode, and different modes can be selected through external GPIO configuration. [0003] refer to figure 1 , in the traditional technology, after the solid-state hard disk leaves the factory, the bootrom of the solid-state hard...
