智能卡差分能量分析实验平台实现与数据优化

随着密码学和密码芯片的广泛应用,针对密码芯片的攻击也日益增多.差分能量分析（Differential Power Analysis,DPA）攻击是最常见的一种侧信道攻击方法.DPA攻击者无须了解加密算法的具体细节,而只通过密码设备的能量迹分析即可破解出设备的密钥.因此,研究DPA攻击十分必要.实现了智能卡DPA实验系统,并对于此系统的能量迹测量数据进行优化处理,从而更有利于针对此类攻击的分析和相应防御措施的设计.

Smart card system implementation and data optimization based on differential power analysis

With the development of the wide implementation of cryptography and crypto chip, the attacks targeting at the crypto chips is increasing. Differential power analysis （DPA） attack is a popular side canal attack method. Through the power trace analysis the DPA attacker can analyze the right key out, not depending on known the details of the crypto algorithm. So the research on DPA attack is essential. In this paper, a smart card system based on DPA analysis is realized. In order to design the security measures against this attack, the energy traces from the DPA attacks are optimized for more accurate data.
