Embodiment 1

[0022] This embodiment discloses a mobile encrypted hard disk with electronic fence function, such as figure 1 As shown in the principle block diagram, the mobile encrypted hard disk includes an encrypted main control chip and a storage medium connected to the encrypted main control chip. The encrypted main control chip is provided with a trusted area and / or an illegal area, and the encrypted main control chip is connected with The positioning module that detects the location of the mobile encrypted hard disk, and the encryption main control chip performs regular inspections on the positioning module to obtain the position information of the mobile encrypted hard disk, so as to determine whether the mobile encrypted hard disk is located in a trusted area or an illegal area.

[0023] The mobile encrypted hard disk in this embodiment also includes an offline power supply module. The offline power supply module includes a battery, a battery management chip, and a single-chip microcomp...

Embodiment 2

[0029] This embodiment discloses an encryption method for a mobile encrypted hard disk with electronic fence function, such as Figure 5 As shown, it includes the following steps: S01). Set a trusted area and / or illegal area in the encrypted master chip. The mobile encrypted hard disk will have a position mark written into the storage space inside the chip during the distribution stage, based on a certain center The distance between the point and the set radius is used to set the credible area, which is the fenced area. The mobile encrypted hard disk is allowed to be used in the trusted area. The main control encryption chip will periodically inspect the Beidou module to obtain location information to monitor whether the module is in the trusted area; illegal areas can also be set, such as an enemy-occupied area on the battlefield , To ensure that once the mobile encrypted hard disk enters the illegal area, the protection mechanism is triggered immediately to ensure the securit...

Abstract

The invention discloses a mobile encrypted hard disk with an electronic fence function, and an encryption method. The encrypted hard disk comprises an encryption main control chip and a storage mediumconnected with the encryption main control chip; a trusted region and / or an illegal region is arranged in the encryption main control chip; the encryption main control chip is connected with a locating module for detecting the position of the mobile encrypted hard disk; the encryption main control chip regularly performs polling on the locating module to obtain position information, thereby judging whether the mobile encrypted hard disk is located in the trusted region or the illegal region; the encrypted hard disk further comprises an offline power supply module; the offline power supply module comprises a battery, a battery management chip and a single-chip microcomputer; the battery is connected with the battery management chip; connection points between the battery and the battery management chip are connected to the encryption main control chip and the locating module through different PMOS transistors respectively; and a gate pole of the PMOS transistor connected with the encryption main control chip is connected to an I / O port of the single-chip microcomputer.

Description

Technical field [0001] The invention relates to a mobile encrypted hard disk and an encryption method of the mobile encrypted hard disk, in particular to a mobile encrypted hard disk with an electronic fence function and an encryption method. Background technique [0002] With the application of secure storage in fields such as national defense, military industry and commercial secrets, as well as the popularization of solid-state mobile hard disks, the security of hard disks has received more and more attention, not only the security of data storage, but also the location of mobile hard disks. There are also certain requirements for the use power of relevant personnel. This requires us to monitor and manage the location of the solid-state mobile hard disk to ensure that the solid-state mobile hard disk cannot be used in illegal locations, or even be destroyed remotely, to ensure that data cannot be obtained through illegal means. Summary of the invention [0003] The technical p...
