Power supply port placement optimization against EMFI
电磁故障注入已成为威胁集成电路安全的一种有效故障注入攻击技术.现有研究表明,电磁故障注入攻击通过在集成电路配电网络上感应寄生电流来干扰电路的内部状态.对电磁故障注入攻击下配电网络的有限元分析发现,感应电流会增加电源网络的压降,导致电路故障.为了解决这一问题,本文提出了 一种电源端口布局优化方法,以减小感应电流的影响.实验结果表明,通过优化电源端口的位置可以将最差的压降降低40%,增强了电源网络的鲁棒性.
Electromagnetic fault injection(EMFI)has become an effective fault injection attack technique threatening integrated circuit(IC)security.Existing research has demonstrated that EMFI perturbs circuits'internal states by inducing parasitic current on the IC power grid.Finite element analysis of the power grid under EMFI shows that the induced current could increase the IR drop of the power grid,leading to circuit faults.Therefore,to address this problem,we propose a power supply port placement optimization approach which reduces the effect of the induced current.The experiment results show that by optimizing the positions of the power supply ports,the worst IR drop can be reduced by 40%,enhancing the robustness of the power grid.
