| 摘 要： | 讨论了一种基于现场可编程门阵列(FPGA)的数据加密标准算法实现.采取资源优先方案,在轮函数内部设置3级流水线,提高了整体处理速度;在FPGA上实现密钥轮函数和密钥变换函数,减少了相邻流水线级间的逻辑复杂度;采用ROM实现了S盒的变换功能,减少了程序对编译器的依赖性.本方法代码效率高,占用系统资源少,极大地提高了算法的整体性能,其设计已经在Xilinx XC2S100e芯片上得到了实现.

| Abstract: | The paper presents a DES implementation based on FPGA and proposes optimal resource scheme.By setting 3 pipeline stages within round function,it accelerates processing speed.By achieving Secret-Key round function and Secret-Key transform function on FPGA,the logical complexity between adjacent pipelines is decreased.The paper also engages ROM to accomplish S-box function and reduces program's dependency on compiler.The approach has high code efficiency and low resource cost,and greatly improves the overall performance.The proposed architecture has been implemented on Xilinx XC2S100e. |
