本文展示了增强的功率（P）和电磁（EM）侧通道分析（SCA）标准（未受保护的）128位高级加密标准（AES）发动机的耐药性（P-AES，128位）和串行（S-AES，8位）DataPaths和128位Simon引擎，带有位式（1位）DataPath，由On-Die Security-Ware Aware全数字低丢失（DLDO）调节器。拟议的DLDO使用控制环诱导的名义DLDO中的扰动提高了SCA抗性，通过功率阶段控制和随机切换噪声注射器（SNI）增强了SCA，并且通过功率阶段控制和随机参考电压（R-VREF）发电机与全数字时钟相结合。调制（ADCM）。 SCA在从130 nm CMOS Testchip获得的测量功率/EM签名上执行的SCA表明，P-AES的测试矢量泄漏评估（TVLA）泄漏的最多可减少p-AES和3579 $ \ times $，2182 $ \ times $，500 $ \ times $ $增加最低轨迹至二链糖（MTD）P-AES的80％， S-AES和SIMON核心分别在相关功率分析（CPA）和相关性EM分析（CEMA）方面。
This article demonstrates enhanced power (P) and electromagnetic (EM) side-channel analysis (SCA) attack resistance of standard (unprotected) 128-bit advanced encryption standard (AES) engines with parallel (P-AES, 128-bit) and serial (S-AES, 8-bit) datapaths and a 128-bit SIMON engine with the bit-serial (1-bit) datapath by an on-die security-aware all-digital low-dropout (DLDO) regulator. The proposed DLDO improves SCA resistance using control-loop-induced perturbations in a nominal DLDO, enhanced by a random switching noise injector (SNI) by power-stage control and a randomized reference voltage (R-VREF) generator coupled with all-digital clock modulation (ADCM). SCA performed on the measured power/EM signatures acquired from a 130-nm CMOS testchip demonstrates up to 25 $\times $ reduction in test vector leakage assessment (TVLA) leakage for P-AES and 3579 $\times $ , 2182 $\times $ , and 500 $\times $ increase in minimum-traces-to-disclose (MTD) 80% of the subkeys for P-AES, S-AES, and SIMON cores, respectively, with respect to correlation power analysis (CPA) and correlation EM analysis (CEMA).
