Embodiment Construction

[0021] In order to make the objects, content, and advantages of the present invention, the specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0022] Such as figure 2 As shown, the high-speed safety hard disk of the present invention is designed to be connected to an external host connection, including a secure encryption protection unit, and N ordinary SATA interface hard drives, secure encryption protection units and N ordinary SATA interface hard drives via SATA interface, respectively. The secure encryption protection unit includes an NVME protocol processing unit, a mapping unit, a N encryption algorithm channel, n storage channel, and a temporary buffer. The security encryption protection unit uses hardware to parse the NVME protocol, parse the command type, sector address, and data load issued by the host. Then map the address information to the corresponding encryption and stora...

Abstract

The invention relates to a high-speed secure hard disk design method and relates to the technical field of computer storage. The present invention adopts the NVMe interface with lower delay and higher speed to connect with the host, and the security encryption protection unit sets multiple encryption algorithms to check the data for encryption and decryption, and sets multiple hard disks to access data in parallel, and the data throughput rate can reach gigabytes The order of magnitude of knots per second greatly improves the performance of the secure hard disk.

Description

Technical field [0001] The present invention relates to the technical field of computer storage, and more particularly to a high-speed safety hard disk design method. Background technique [0002] The secure hard drive is a computer storage device for securely enhanced design to protect user data security. [0003] Traditional security hard drives use a traditional hard disk interface, single algorithm nuclear encryption, and single-hard disk storage data architecture. The traditional hard disk interface is an IDE interface or a SATA interface, which is limited to the number of levels per second per second. Single algorithm nuclear encryption, the architecture of single-hard disk storage data also limits the data throughput of traditional security hard drives. Traditional security hard disk composition block diagram figure 1 Indicated. [0004] It can be seen that the traditional security hard disk is limited to encryption technology, interface speed, or hard disk itself access s...
