侧信道攻击中的高阶模板攻击研究

Research on High Order Template Attack in Side Channel Attack

当下的侧信道攻击中,用于抵抗一阶DPA攻击的掩码对策,在使用上较为广泛。针对与该对策所实施的高阶DPA攻击在攻击成本和成功率上存在较大缺陷。本文将介绍针对于掩码对策进行的高阶模板攻击,以及相对应的数学模型和算法,用以改善国内外现有攻击技术的不足。数据的处理与实验采用Matlab平台,实验结果将证实此方法的可行性。

In the side channel attack, the mask implementation which is used to resist the first-order DPA attack is widely used at present. There are great defects in the high-order DPA with this implementation both in the cost and rate. In order to improve the deficiencies of existing domestic and foreign attack technology, we will introduce the high-order template attacks for masked implementation and its mathematical models and algorithms. The data processing and experiment are based on Matlab platform, and the results will prove the feasibility of the method.
