The structure of the traditional solid-state hard disk determines that it can only be recognized as a disk when it is connected to a computer. In the existing technology, when the host loads the solid-state hard disk, some hard disk data is modified by software means to hide some partitions of the solid-state hard disk, but this This method depends on the operating system platform, which has potential security risks and is easy to be cracked by unauthorized persons using Trojan horses or loopholes; illegal intruders who are familiar with the operating system file format can display the partition by modifying the hard disk data
In general, the hidden partition at the application level is not thorough enough, and theoretically it can be cracked by an illegal intruder who is familiar with the file format of the operating system

Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings.
[0031] The architecture of traditional solid-state drives determines that when they are connected to a computer, they can only be recognized as a disk, which is not convenient for user data management; when users use hard drives, they usually divide them into multiple partitions, so usually through operating system level The software realizes partial partition hiding of the disk, but this cannot guarantee data security. At the same time, the solid-state hard disks in the prior art all initialize the solid-state storage medium through the main control chip to complete the physical address space allocation. The hard disk partition information of the boot record is realized; (2) modify the physical capacity data of the hard disk by modifying the device identification command (Identify DeviceCommand) command required in the data communication protocol (such as SATA); (3) s...

The invention discloses a safe solid state disk capable of hiding disk and a method. The safe solid state disk comprises an interface module, an identify information input device, a solid state storage medium and a solid state disk controller. The solid state disk controller at least comprises a master control chip, a Hub controller, an identity authentication module and a cache module. The Hub controller is equipped with multiple virtual interfaces and multiple hidden virtual interfaces. When the safe solid state disk accesses a host, the Hub controller sends the identification code of each virtual interface to the host through the interface module; each virtual interface is identified as an independent disk in the host; only after the identity authentication is successful, the master control chip can control the Hub controller to send the identification codes of the hidden virtual interfaces to the host; and each hidden virtual interface is identified as the independent disk in the host. Through adoption of the technical scheme of the safe solid state disk and the method, multi-disk control can be realized in a computer by accessing the single solid state disk; the disk can be hidden; and the safety performance of the solid state disk can be improved.
Description
technical field [0001] The invention relates to the technical field of solid-state hard disk storage, in particular to a safe solid-state hard disk capable of hiding a magnetic disk and a method thereof. Background technique [0002] At this stage, data storage security has attracted much attention, and solid-state drives with encryption functions are increasingly widely used. The structure of the traditional solid-state hard disk determines that it can only be recognized as a disk when it is connected to a computer. In the existing technology, when the host loads the solid-state hard disk, some hard disk data is modified by software means to hide some partitions of the solid-state hard disk, but this This method relies on the operating system platform, which has potential security risks and is easily cracked by unauthorized persons using Trojan horses or loopholes; illegal intruders who are familiar with the operating system file format can display the partitions by modifyi...
