摘    要:研究分析数据加密算法DES的特点,采用差分功耗分析(DPA)攻击方式进行密钥破解,针对DES算法实现一种差分功耗分析攻击仿真平台。该仿真平台具有精度高、模拟速度快等特点,其理论基础为集成电路中门电路在实现加密算法时的物理特性、功耗模型及数据功耗相关性。在该平台上针对DES加密系统,采用基于汉明距离的差分功耗攻击实现仿真模拟,成功破解了DES加密算法的密钥,从而给DES加密算法理论研究者提供了有益的基础和参考。

关 键 词:DES  差分功耗攻击  汉明距离  仿真平台

Abstract:By analyzing the features of data encryption algorithm DES,this paper presented a differential power analysis(DPA) attacking simulation platform on DES.The platform has some advances such as high precision and high simulation speed.All its theories are based upon the physical characters,power consumption models and data dependent power consumption of CMOS logic gates which form the integrated circuits(ICs).The paper introduced the design and realization of DPA attacking platform of DES,which is based on hamming distance.Correct secret key of encryption algorithm is cracked successfully with simulation experiment.The work in this article provides necessary base and reference for theoretic research on DES algorithm in the future.
Keywords:DES   Differential power analysis attacks   Hamming distance   Simulation platform
