摘要
分析差分能量分析原理的基础上,设计了针对DES加密算法的差分能量分析系统并得出了分析的正确率。通过对实验数据的深入观察和分析,发现了可能严重影响DES的DPA分析正确率因素——DES的第四个S盒冲突现象,值得进一步深入研究。
Based on the thorough analysis of the Differential Power Analysis theory,a DES-oriented DPA system is designed in this paper and the DPA analysis correct rate is achieved.Through detail observation and analysis of the experimental data,we＇ve found one factor which may seriously affect the DES＇ DPA analysis correct rate,that is the 4th S-Box collision phenomenon which is deserved to be researched deeply in the future.
