Decentralized mobile hard disk encryption and decryption method and system

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...

AI Technical Summary

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 multiple users; fifth, there is a certain dependence on the host system and can only support certain specific Architecture or operating system host, such as x86 (microprocessor) or IA64 (processor) system; sixth, if you need to bring your own operating system and file system, copyright issues and compatibility issues are involved

[0008] In summary, the existing hard disk encryption technology obviously has inconvenience and defects in actual use, so it is necessary to improve it
