An Enhanced-Security Buck DC-DC Converter with True-Random-Number-Based Pseudo Hysteresis Controller for Internet-of-Everything (IoE) Devices

📋 论文概要

该论文提出了一种增强安全性的降压DC-DC转换器，采用基于真随机数的伪迟滞控制器，以解决传统线性反馈移位寄存器（LFSR）在功率注入攻击（PIA）下可预测和可重现的安全漏洞，同时降低电磁干扰（EMI）。

💡 主要创新点

• 提出基于真随机数（TRNG）的伪迟滞控制机制，替代传统LFSR，增强对功率侧信道攻击和功率注入攻击的抵抗能力。
• 通过随机化开关频率和占空比，有效降低EMI并提高电源管理系统的安全性。

Internet-of-Everything (IoE) devices are concerned, strong security and low electromagnetic interference (EMI) are design requirements for power management to guarantee personal data protection. [1] is robust under power side-channel attacks (PSCA), but a power injection attack (PIA) results in limited random-number generation (RN), as shown in the upper left of Fig. 7.5.1. The loop randomization technique in [1] is cracked and vulnerable to PIA, since predictability and reproducibility arise in the linear feedback shift register (LFSR). Moreover, the PIA narrows the LFSR-based random switching frequency (fSW) in
