摘要
根据密码芯片光辐射的数据相关性,利用时间相关单光子计数技术搭建了光辐射分析实验平台,对基于模板的光辐射分析攻击进行分析。通过对光辐射迹进行模板刻画、构建策略和匹配方法的讨论,结合密码芯片光辐射的数据相关性,采用基于光辐射汉明重量模型的方法进行模板构建,并选取高级加密标准(AES)加密算法第一轮加密的S盒输出作为攻击点,结果表明基于该方法的模板匹配相较汉明距离等其他模型具有更加精确的匹配度。成功实施基于模板的光辐射分析攻击。
In view of the data correlation of cryptographic chip’s optical radiation, using time-correlated single photon coun-ting techniques to build photonic emission analysis attacks experimental platform, this paper analyzed template based photonic emission attacks.It discussed the trace of photonic emission to portray template, built strategies and matching methods.Then, it portrayed template by using Hamming weight model and chose the S-box of the first round of advanced encryption standard （AES） encryption algorithm as the point of attack to implement successfully the template based photonic emission attacks.The result shows the template based photonic emission attacks is more efficient than other models.
