Management-use separated computer encryption lock

Abstract

A management-use separated computer encryption lock includes an encryption board inserted between a main board and a hard disk of a computer; an electronic key which is inserted in the encryption board and can perform real-time identity authentication with the encryption board; the electronic key and the encryption board perform real-time identity authentication and firmware anti-copy detection, and perform encryption on data accessing between the electronic key and the encryption board; after identity authentication and firmware anti-copy detection is completed, the electronic key combines a part of user key lists stored in an inner part and a part of user key lists of the encryption board, and a part of user keys are randomly selected from the key lists according to different storage partitions of the hard disk to perform encryption on data accessing the hard disk. The security of the computer encryption lock is high, the firmware will not be copied, encrypted data in the hard disk and electronic key and encryption board communication data are encrypted and will not be cracked, and the confidentiality is high.

Description

technical field [0001] The invention relates to an electronic password lock, in particular to a computer encryption lock with separated functions. Background technique [0002] At present, the vast majority of information security products mainly protect the outside of the information like a firewall, but do not deal with the protection of the information itself, that is, do not encrypt and decrypt the stored information, and only add an encryption device at the information output end. encryption. For reasons such as ignorance, misunderstanding, or trouble, users of such encryption devices may leak information once they violate regulations during information use, such as dismantling the encryption device or privately connecting lines. [0003] At present, there is also a product that encrypts the source of information, but this product generally has shortcomings such as hardware being easily cloned and inconvenient to use. Contents of the invention [0004] The technical...

AI Technical Summary

Problems solved by technology

Users of this kind of encryption device may leak information due to negligence, misunderstanding, or troublesome operations in the process of information use, such as dismantling the encryption device, or privately connecting lines, etc.

[0003] At present, there is also a product that encrypts the source, but this product generally has disadvantages such as hardware being easily cloned and inconvenient to use.
