智能卡芯片的差分能量分析攻击研究

Differential Power Analysis Attacks on Smart Card

本文主要研究智能卡芯片中DES算法的差分能量分析攻击。首先,在分析研究能量分析攻击的原理和常用攻击方法的基础上,采用基于S盒的功耗区分函数,以一种与以往文献中不同的攻击方法来对智能卡中DES算法进行了密钥破解;然后,基于Inspector SCA平台实现了这一攻击过程,成功获取了完整密钥。

This paper studied the differential power analysis attacks on smart card with DES algorithm.Firstly,we took the power distinguish function base on the S-box and decoded the DES algorithm on smartcard with a different way from previous literature which depended on the principle and common methods of power analysis attacks. Then we made use of the Inspector SCA platform to implement this attack,and achieved the complete key.
