PRIDES: A Power Rising Descending Signature for Improving IoT Security
Ashish Mahanta, Haibo Wang · 2023
This work presents a novel digital signature to characterize the rising and descending patterns of IoT device power consumption, which can be used to detect abnormal operations. The digital signature, referred to as PRIDES, can be generated using simple digital-like circuits and hence incurs very low hardware overhead. A novel PRIDES generation circuit is implemented with a 90 nm CMOS technology and its operation is validated via transistor-level simulation. A PRIDES-based methodology to detect the insertion of potentially malicious codes is presented and its effectiveness is demonstrated with using power consumption data measured from hardware experiments.
