查询词典 cipher machine

Different from all other current file encryption systems which are also based on DES, our Enhanced File Encryption System is following X9.17 key generation standard to ensure the strength of the primary key, utilizing Cipher Block Chaining mechanism to hold the text structure, and introducing cache technique and Bit / Byte mapping algorithm to enhance the efficiency while reducing the complexity of the system.

与当前许多基于 DES 的文件加密系统不同，我们的增强型文件加密系统采用 X9.17密钥生成规范确保用户主密钥的强度，采用密文分组链接方式保护密文的结构信息，并且通过缓存技术和位/字节映射算法提高系统的执行效率、降低系统的复杂度。

The one-way coupled map lattices and initial condition generation function based on iterative Logistic map are used to realized the data confusion and diffusion between plain-text and key information. And the cipher block chaining mode is used to generate the 128-bit Hash value for plaint-text with arbitrary length.

该方法通过使用单向耦合映射格子和基于迭代Logistic映射的初始状态生成函数实现明文和密钥信息的混淆和扩散，并基于密码块连接方式产生任意长度明文的128位Hash值。
