Problems solved by technology

[0007] However, the existing disk security encryption system has the following defects: first, if it is encrypted by pure software, the performance of the system will inevitably be reduced; second, the key and password are stored on the disk, which increases the possibility of cracking the disk data; Three, additional disk encryption and authentication partitions are added, which reduces disk utilization; fourth, the key is unique, which is not conducive to authorizing mult

Embodiment Construction

[0054] Such as figure 1 As shown, the embodiment of the present invention is a decentralized mobile hard disk encryption and decryption method, which includes the following steps:

[0055] S1. Configure and store the unique identification code corresponding to the mobile hard disk on the remote server, and configure multiple sets of mobile hard disk permission driver loading programs and hard disk running basic driver loading programs in the remote server, and configure the file opening permission corresponding to each set of permission driver loading programs;

[0056]The basic driver loading program running on the hard disk is only used to obtain the user's verification information; the mobile hard disk authorization driver loading program is used to restore and load the data in the hard disk after running. And it will be automatically destroyed after each use, which is realized by the built-in timer of the mobile hard disk authority driver loader. Since the mobile hard dis...

Abstract

The invention discloses a decentralization-based mobile hard disk encryption and decryption method. The method comprises the following steps of S1, configuring a unique identification code corresponding to a storage mobile hard disk at a remote server, configuring multiple sets of mobile hard disk permission driver loading programs and a hard disk operation basic driver loading program in the remote server, and configuring a file opening permission corresponding to each set of permission driver loading program; S2, configuring a mobile hard disk trusted device list in the remote server; S3, obtaining mobile hard disk loading information, and sending the mobile hard disk loading information and corresponding device loading information to the remote server; S4, configuring the file opening permission corresponding to a legal user in the mobile hard disk by the remote server; and S5, judging whether a device is in the configured mobile hard disk trusted device list or not according to device information by the remote server.

Description

technical field [0001] The invention relates to the technical field of disk encryption and decryption, in particular to a decentralized mobile hard disk encryption and decryption method and system. Background technique [0002] Today, with the rapid development of computer technology, the protection of hard disk data has become particularly important. Therefore, hard disk encryption technology has also become the research direction of many technicians. Hard disk encryption technology refers to the technology that saves user data on the hard disk after generating new encrypted data through some reversible encryption algorithms. This technology provides high security protection for important data information such as customer information and business secrets, preventing unauthorized data access. Even if the hard disk is stolen, it is difficult to read the important data on the hard disk. [0003] Existing hard disk encryption technology methods, devices and systems mainly co...
