该论文提出一种面积仅1200µm²的物理随机数生成器,基于SiN MOSFET实现,适用于安全智能卡应用。通过利用SiN MOSFET的随机噪声特性,在极小面积内生成不可预测的随机数,解决了传统物理随机数生成器面积过大的问题。
financial transactions and the transfer of confidential information. Small circuits for high-level information security have to be implemented in these chips. These secure circuits thus require a small ph-RNG (physical random-number generator) capable of generating unpredictable random numbers. A smart card of just a few mm2 is almost entirely occupied by the CPU, coprocessor, random logic, ROM, RAM, EEPROM, etc., and the memory capacity required is increasing. However, the circuit area of previous ph-RNGs is large, since there is a complex trade-off among circuit area, quality of random numbers and data generation rate. To solve the tradeoff, we use SiN MOSFET as a noise source device, and design a compact A/D converter for SiN MOSFET RNG. Together these components form a compact ph-RNG
