Optical disk multi-segment recording encryption method based on XTS encryption mode

Abstract

The invention discloses an optical disk multi-segment recording encryption method based on an XTS encryption mode. The method comprises steps of firstly dividing an optical disk into a parameter region and a data region to carry out recording respectively, carrying out scrambling processing on parameter information during recording of the parameter region, and carrying out optical disk sealing on the optical disk after the recording is finished; then, using a USB CD-ROM drive detection module to finish identification and configuration of a USB CD-ROM drive device; using a USB CD-ROM drive control management module to carry out authentication and verification of a user identity and an access authority on the USB CD-ROM drive device and according to the configured security strategy, managing and controlling the USB CD-ROM drive device; using a USB data analysis module to analyze and access a command block package required by the USB CD-ROM drive deice and to control command operation and USB data operation in a shunting manner; and using a data security service module to provide security protection services and security management services based on a section full disk protection function by use of a high speed bus port. According to the invention, the security protection ability for conversion through the optical disk of an electronic file is sufficiently improved and it is convenient for a user to use the method.

Description

technical field [0001] The invention relates to an encryption method for multi-segment recording of an optical disc based on an XTS encryption mode. Background technique [0002] When electronic documents need to be exchanged offline between physically isolated networks, between stand-alone computers or between networks, CD-ROMs are often used as storage media for sensitive information. The use of optical disc exchange has the advantage of being convenient for handover and destruction. However, at present, data input and output control software is usually used to operate the optical drive to burn for data exchange disc production. The data stored on it is generally protected by public algorithms and password encryption, which is safe Protection is limited. When the disc is out of control, the data stored on the disc can be directly read through the ordinary optical drive, and the plaintext of the data may be restored by using analysis and cracking tools.
