Document Type and Number:
WIPO Patent Application WO/2017/101122
Kind Code:
A1
Abstract:
A computer encryption lock having separating management and use, comprising an encryption board (100) spliced between a motherboard (500) and a hard disk (700) of a computer, and an electronic key (300) spliced on the encryption board for use in real-time authentication with the encryption board; the electronic key and the encryption board are used for real-time identity authentication and firmware anti-copy detection, and used for encrypting the data transmitted between the electronic key and the encryption board; after the identity authentication and firmware anti-copy detection are completed, the electronic key combines a number of internally stored user key lists and a number of user key lists on the encryption board, and randomly selects a number of user keys from the key lists according to different storage partitions in the hard disk, so as to decode the data transmitted to and from the hard disk. The computer encryption lock is highly secure, wherein firmware cannot be copied, and following encryption, encrypted data in the hard disk and data communicated between the electronic key and the encryption board cannot be decrypted, thus ensuring high degree of security.
