摘　　要：伴随着信息技术的不断发展,U盘加密系统已成为商业保密中的重要内容,在U盘加密过程中涉及商业安全和社会公共安全的公文有可能会被破坏和截取,因此为了保护公文的机密性、完整性,防止公文被泄密、篡改,同时也为了加强公文高级保密,必须采用一种新的技术——多级加密技术,使其能达到更高的保密效果.首先简单介绍了研究背景、研究的必要性、多级加密的原理等内容;其次介绍了多级加密技术原理和多级加密技术的设计过程;最后利用高级程序设计语言C#在微软.NET开发工具中实现了多级加密的综合性技术,最终解决U盘加密内容的安全问题.With the continuous development of information technology,the U disk encryption system has become important content in the commercial confidentiality,in the U disk encryption process involving the business security and social public security,document is likely to be damaged and interception,in order to protect the confidentiality,integrity of documents,prevent the document from being leaked,tampered with;at the same time,in order to strengthen the senior confidential documents,as well as to the U disk holders or participants to recognize validated,must adopt a new technology—multi-level encryption technology,make it can achieve higher secrecy.Firstly briefly introduces the research background,research of the theory,principle of multilevel encryption,etc.Secondly introduces the principle and the design process of multi-level encryption technology.Finally using high-level programming language c#on Microsoft.NET development tools to realize the comprehensive technologies based on multilevel encryption,finally solves the security problems about the content of U disk encryption.
