A secure USB disk for solid state disk authentication

Abstract

The invention discloses a secure USB disk for solid state hard disk authentication, the secure USB disk comprising at least a first interface module, a USB disk controller, a first authentication module and a user login management module. An operating system is built in the U disk controller for starting when the host computer detects the access of the secure U disk and completing the U disk authentication operation and the user authentication operation with the SSD accessed to the operating system by the operating system. When the USB disk authentication and the user authentication are successful, the USB disk controller sends an unlock instruction to the SSD to unlock the SSD, otherwise, the SSD is in a fully locked state. Through the technical scheme of the invention, only after the authentication of the U disk and the authentication of the user are passed, can the encrypted solid-state hard disk uniquely corresponding to the encrypted solid-state hard disk be decrypted.

Description

technical field [0001] The invention relates to the fields of data encryption, data storage, data transmission and data authentication, in particular to a safe USB disk used for solid-state hard disk authentication. Background technique [0002] With the continuous development of science and technology, the data security of computer hard drives has always been the focus of social attention. Due to the progress in flash memory device technology, solid state drives have been greatly strengthened as the preferred storage medium. consolidate. In recent years, due to the theft of information in solid-state drives, serious leakage problems have been caused, and in some special fields such as aerospace and financial fields, there are high requirements for data security, and there is a need for safe destruction of original data in solid-state drives. Therefore, it is extremely important to perform high-strength encryption on solid-state drives. [0003] The encryption method of so...

Problems solved by technology

[0005] In short, the security, operability and efficiency of the encryption method or authentication method of the solid-state hard disk currently on the market are not very high. In order to meet the above requirements, there is also a U disk in the prior art to perform related operations combined with the solid-state hard disk. , see patent application document 105354479A, a solid-state hard disk and data hiding method based on U-disk authentication (application number is 201510737530.9), however, in the technical solution recorded in this patent document, the U-disk introduced is only used as a load-bearing transmission solid-state hard disk The medium of the safe storage area key, that is, when the USB flash drive is inserted, there will be an extra partition on the SSD module. This partition is the area where the encrypted information that needs the key to open is located. It is easy to be cracked by unauthorized persons using holes, which greatly reduces the security of data

[0006] At the same time, in terms of hard disk data destruction, the existing technology mainly uses special data destruction software to repeatedly erase and write the hard disk. However, the defect of this data destruction method is that the data is not completely destroyed, especially for Solid-state hard drives, it is difficult to completely destroy data, and it takes a long time to destroy
