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。

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.
