Problems solved by technology

One is to encrypt the data information itself stored in the mobile media, but this is generally only applicable to personal behaviors. For companies or enterprises, this is not conducive to business trips or going out to work
The second is to prevent data leakage on mobile media by hiding encrypted partitions and PKI technology. However, in this way, the media is still stored in plaintext, and the transmission of plaintext in the process of interacting with other terminals is also very easy to cause leakage.

Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings. As a part of this specification, the principle of the present invention will be described through embodiments. Other aspects, features and advantages of the present invention will become clear at a glance through the detailed description.

[0025] Such as figure 1 , 2 As shown, A1: pre-cure the storage module including the authentication module, the hardening module, the core driver module, etc. on the removable medium.

[0026] A2: Connect the mobile media to a terminal such as a PC.

[0027] A3: The core driver module senses the connection and activates the chip of the authentication module.

[0028] A4: The authentication module starts and requires the user to authenticate. Authenticated users can use or access all content on the removable media. Users who have not passed identity authentication or have wrong identity authentication will not be able to access th...

Abstract

The invention discloses an encryption method supporting a mobile media. According to the method, encryption and decryption functions are solidified on the mobile media whose functions are protected by an authentication mode. Compared with the traditional method in which the encryption and decryption functions must be installed on a PC terminal, the method of the present inventyion is more convenient in that the mobile media is easier to carry. When a user needs to work in different locations, files require no decryption for that encrypted files can be directly transmitted on the internet without the worry of risk of secret leakage; when the user come to a different location, the mobile media can be connected with any one of PC terminals for the user to use the encrypted files.

Description

technical field [0001] The invention belongs to the technical field of computer information security, and in particular relates to an encryption method supporting mobile media. Background technique [0002] At present, there are generally the following methods for data protection of removable storage devices (such as: mobile hard disks, U disks, SD cards, optical discs, etc.). One is to encrypt the data information itself stored in the mobile media, but this is generally only applicable to personal behaviors. For companies or enterprises, this is not conducive to business trips or going out to work. The second is to prevent data leaks on mobile media by hiding encrypted partitions and PKI technology. However, in this way, the media is still stored in plain text, and plain text transmission in the process of interacting with other terminals can easily cause leaks. Contents of the invention [0003] The invention provides an encryption method supporting mobile media, using ...
