中文摘要: 提出了一种支持数据保密的光盘文件系统以及适用于数字光盘的数据保密方法。改进了ISO 9660 Level 2标准的光盘文件系统, 划分为明文区、保密区和参数区三部分, 分别存储明文、密文和参数数据。光盘制作模块将明文数据、密文数据及参数数据制作成光盘文件系统的镜像文件, 同时将光盘阅读模块注入到明文区。光盘阅读模块专门存取保密区数据。该方法能实现明文、密文数据及其解密工具并存于同一光盘, 无需安装额外的软件, 该文件系统兼容目前所有的光盘设备。
Abstract:A new file system of data protection for optical disc and its data protection method were proposed. This file system was divided into plaintext section, ciphertext section and parameter section. A producer of file system was suggested to pack plaintext, ciphertext, parameter in one ISO image file. A special reader for accessing ciphertext section was injected into plaintext section. This method bound plaintext, ciphertext and the special reader together, and needn’t any extra software. This file system is compatible with all optical disc devices.
