一种基于Ukey的分组加密信息保护系统

An Information Encryption System Based on Block Cipher and Ukey Technology

摘要: 针对文件安全问题，本文综合利用了身份认证、文件加密、信息隐藏、Ukey存储控制等安全关键技术，并基于独特的“分组加密 + 文件分割”工作模式，开发一套安全易用的信息加密系统。系统在改进和优化已有加密算法的基础上，提出了自主开发的分组加密模块，实现了文件的高效安全加解密，可支持加密原文件深度擦除和不同用户的不同的加密级别需求，有效弥补了目前已有加密系统的不足。

Abstract: To deal with file security problems, this paper made a comprehensive utilization of identity authentication, file encryption, information hiding, Ukey storage control and other critical safety technologies to develop a safe and easy using information encryption system based on the unique block cipher & file segmentation mode. Based on improving and optimizing the existing encryption algorithms, our system has achieved a result of safe and efficient file encryption and decryption with the use of self-developed encryption module while supporting file safety erasing and different encryption level, which effectively compensates for the deficiencies of existing encryption system.
