真随机数发生器（TRNG）是安全系统中的关键组件，用于生成会话密钥、认证协议的挑战和秘密共享的掩码。不幸的是，TRNG容易受到各种物理攻击，从被动观察生成的数字到主动操纵。在这项工作中，我们调查的敏感性的过渡效应环振荡器（TERO）TRNG主动操纵攻击。特别是，我们执行低功耗和低温攻击的实现上运行的TERO Xilinx斯巴达6 FPGA和实验评估的有效性，作为对策的四个在线测试。
True random number generators (TRNGs) are critical components in security systems used to generate session keys, challenges for authentication protocols and masks for secret sharing. Unfortunately, TRNGs are vulnerable to a wide class of physical attacks ranging from passive observation of generated numbers to active manipulation. In this work we investigate the susceptibility of the Transition Effect Ring Oscillator (TERO) TRNG to active manipulation attacks. In particular we perform underpower and low temperature attacks on an implementation of the TERO running on a Xilinx Spartan 6 FPGA and experimentally evaluate the effectiveness of four online tests as countermeasure.
