基于FPGA实现AES的侧信道碰撞攻击

Side-channel collision attack based on the FPGA implementation of AES

为了解决攻击点在能量迹中具体位置的识别问题,在对侧信道碰撞攻击技术研究的基础上,提出了通过计算能量迹中每个采样点的方差来识别攻击点的方差检查技术。并利用基于相关系数的碰撞检测方法,对一种AES的FPGA实现实施了攻击。实验结果表明,方差检查技术可以有效地识别攻击点在能量迹中的具体位置。

To solve the problem on the identification of location of the attack point in the energy traces,this paper puts forward the variance inspection technology,which computes variance of every sampling points in energy traces to identify the attack point,based on the research of side-channel collision attack.What＇s more,this paper implements an attack to the AES FPGA implemented by the use of correlation-based collision detection method.The result shows that the variance detection technology can effectively identify the location of the attack point in the energy traces.
