基于FPGA加密芯片的DPA实现与防御研究

摘要

Differential Power Analysis（DPA） is cracked AES cryptographic algorithm most effective a attack technology,to prevent this kind of attack technology based on FPGA build experimental platform to achieve AES encryption algorithm,based on this attack DPA stands on through the mask technology and mask technology AES encryption algorithm to optimize and improve.Through the experiment proved that the improved algorithm can effectively prevent the AES DPA stands against.%差分功耗分析是破解AES密码算法最为有效的一种攻击技术,为了防范这种攻击技术本文基于FPGA搭建实验平台实现了对AES加密算法的DPA攻击,在此基础上通过掩码技术对AES加密算法进行优化与改进。通过实验证明改进后的AES算法能有效的防范DPA的攻击。
