基于FPGA的DES加密芯片的设计

Hardware design of DES algorithm based on FPGA

通过对DES加密原理的分析,推导出了DES的算法公式,通过对算法中核心部分的数学分析和化简,借助Verilog语言与C语言编程以及EDA设计软件的帮助,实现了DES算法的FPGA条件下的重构设计,同时对密钥的动态管理提出了新的设计方案。最后,通过对设计结果的功能仿真和测试分析,论证了整个设计过程的正确性。

This paper introduces the basic principles of the DES encryption system,achieves the optimum FPGA reconstructing design on the DES with the help of giving the algorithm of DES encryption under the Verilog language and the C language conditions and the effective dealing with the key issues.Then it gives a new dynamic management design programme of the keys.Finally,the results of the design function simulation and test analysis show that the design of the whole thesis has higher practical significance and value.
