Application-Specific Integrated Circuit (ASIC)-resistant Proof-of-Work (PoW) is widely adopted in modern cryptocurrency. The operation of ASIC-resistant PoW on ASIC is designed to be inefficient due to its special features. In this paper, we firstly introduce a novel ASIC-resistant PoW for low-end microcontrollers. We utilized the measured power trace during the cryptographic function on certain input values. Afterward, the post-processing routine was performed on the power trace to remove the noise. The refined power trace is always constant information depending on input values. By performing the hash function with the power trace, the final output was obtained. This framework only works on microcontrollers and the power trace depends on certain input values, which is not predictable and computed by ASIC.

基于低端微控制器功率分析的耐ASIC工作证明

耐专用集成电路（ASIC）的工作量证明（PoW）在现代加密货币中被广泛采用。ASIC上的ASIC抵抗PoW的操作由于其特殊功能而被设计为低效的。在本文中，我们首先介绍了一种适用于低端微控制器的新颖的耐ASIC的PoW。我们在某些输入值的加密功能期间利用了测得的功率轨迹。之后，对电源走线执行后处理程序以消除噪声。精确的功率曲线始终是恒定的信息，具体取决于输入值。通过对功率跟踪执行散列函数，可以获得最终输出。该框架仅适用于微控制器，功率曲线取决于某些输入值，而这是ASIC无法预测和计算的。
