摘　　要：根据改进的动态差分掩码防护逻辑以及集成电路的半定制流程设计高级加密标准S盒,采用TSMC0.18μm工艺实现基于3种不同逻辑单元的S盒,并对其抗电磁侧信道攻击性能进行评估。实验结果表明,基于掩码防护逻辑的S盒电磁辐射与输入数据相互独立,能克服双轨电路信号线不平衡导致的信息泄漏问题,从而增强电路的抗电磁侧信道攻击能力。This paper implements a S-box of Advanced Encryption Standard（AES） based on improved Masked Dynamic Differential Logic（MDDL）and semi-custom design flow.The experiment is finished three kinds of S-boxes which are based on different logic cell respectively and adapted the technology of TSMC0.18 μm.The ability against electromagnetic analysis of these S-boxes are evaluated.Experimental results show that electromagnetic emission produced by S-box based on the given defending logic is independent with input data.The new S-box can solve the problem of information leakage caused by the unbalanced dual signal,the capability of defending electromagnetic side-channel attacks of S-box is increased significantly.
