Embodiment 1

[0020] The data storage method of SSD hard disk: when storing data in SSD hard disk, the encryption algorithm is used to encrypt the storage address of the data in the SSD hard disk controller, and the continuous data is divided into very small blocks;

[0021] Data reading and writing method: When SSD hard disk reads data, the SSD hard disk controller first converts the system instructions through the key algorithm, then reads the data of the corresponding address, and finally puts the read data in the RAM internal cache and sent to the host;

[0022] How to destroy data: When destroying data on an SSD hard disk, press the destroy button first. After the SSD hard disk controller receives the trigger level of data destruction, it will immediately destroy the data address conversion key stored in the SSD hard disk controller. After the key is destroyed, the data stored in the SSD hard disk will become a mess, and no valid data can be read, and the SSD hard disk has been destroy...

Embodiment 2

[0025] The data storage method of the SSD hard disk: first store the key in the SSD hard disk controller, and use the encryption algorithm to encrypt the storage address of the data in the SSD hard disk controller when storing data in the SSD hard disk, and divide the continuous data After being divided into extremely small blocks, they are stored in different FLASHs;

[0026] Data reading and writing method: When SSD hard disk reads data, the SSD hard disk controller first converts the system instructions through the key algorithm, then reads the data of the corresponding address, and finally puts the read data in the RAM internal cache and sent to the host;

[0027] How to destroy data: When destroying data on an SSD hard disk, press the destroy button first. After the SSD hard disk controller receives the trigger level of data destruction, it will immediately destroy the data address conversion key stored in the SSD hard disk controller. After the key is destroyed, the dat...

Abstract

The present invention discloses a fast and reliable design method for destroying a SSD hard disk. The method for destroying the SSD hard disk is implemented by three steps of changing a data storage mode, a data reading / writing mode and a data destruction mode of the SSD hard disk. Compared to the prior art, in the fast and reliable design method for destroying the SSD hard disk, a data storage architecture, the data reading / writing mode and the data destruction mode of the SSD hard disk are changed, so that the rapidity and reliability of data destruction are ensured, and the data is effectively prevented from being maliciously tampered, stolen and leaked.

Description

technical field [0001] The present invention relates to the technical field of hard disk destruction, specifically a design method for quickly and reliably destroying SSD hard disks. Background technique [0002] SSD hard disk, referred to as solid disk, Solid State Drive (Solid State Drive) is a hard disk made of solid-state electronic storage chip array, which consists of a control unit and a storage unit (FLASH chip, DRAM chip). SSDCONTROLLOR is the solid state drive controller. [0003] At present, people pay more and more attention to data security. In recent years, hard disk information leakage incidents have emerged one after another. Therefore, hard disk destruction technology has become an urgent need for individuals and enterprises, especially the military. Now hard disk destruction technology is common and diverse. For For SSD hard disks, traditional SSD destructible hard disks are basically the same as conventional SSD hard disks in the way of reading and writin...
