提出了一个基于嵌入式Linux系统的智能电话信息终端,将计算功能和电话功能有机地结合起来。通过在S3C2410嵌入式开发板上移植ARM Linux嵌入式系统,并配置各种驱动程序,构造图形用户界面,同时利用开源项目来开发各种应用程序,因此该终端不但能提供基本的个人信息管理和电话呼叫管理等功能,还能实现浏览器、电子邮件和MSN Messenger等网络功能,从而使电话机成为一个方便实用、功能强大的智能信息终端。-Proposed a system based on embedded Linux smart phone information terminals, the calculation function and telephone function combine. Through the embedded development board S3C2410 transplant ARM Linux embedded system, and configure a variety of drivers, graphical user interface structure, while the use of open source projects to develop various applications, so the terminal will not only provide basic personal information management and telephone call management features, but also realize the browser, e-mail and MSN Messenger and other network functions, so that phone into a convenient and practical, powerful, smart information terminals.

随着密码分析技术的提高，新的数据加密标准AES取代了过时的DES。文章在阐述AES/RSA加密算法的基础上，分别给出了利用AES/RSA实现客户端/服务器端网络数据传输的加密流程。最后在比较AES算法和RSA算法基础上，将AES与RSA相结合提出一种新的数据加密方案。-analysis technology improvements, new data encryption standard AES replaced the outdated DES. The article described AES/RSA encryption algorithm on the basis of the difference is the use of AES/RSA achieve client/server network data encryption process. Finally in comparison AES and RSA algorithm, based on AES and RSA will be combined, a new data encryption program.
