基于ARM的3DES加密算法实现

Implement of 3DES Encryption Algorithm Based on ARM Processor

3DES算法是一个重要的对称加密算法,被广泛应用于实际系统中。目前并没有针对嵌入式的实现方法,依据3DES算法和一般嵌入式系统需求,详细介绍该系统硬件和软件的设计过程。硬件以三星公司的S3C2410处理器为核心,系统以嵌入式Linux为载体。在此详细阐述开发环境的搭建、Bootloader的架构及功能、内核及文件系统的编译和移植。基于系统硬件和软件设计过程,通过MiniGUI图形界面对3DES算法进行了演示。

3DES algorithm is an important symmetrical encryption algorithm,which is widely used in actual system.Because there is not a good method to build it in embedded system at present,based on ARM processor,an embedded encryption system is implemented.The system′s hardware and software design process are illustrated,including Bootloader,Linux kernel and file system transplant and compiling.This system is based on S3C2410 ARM processor.A graphic 3DES encryption software based on MinGui platform is developed.
