Abstract
A power fingerprinting system is adopted for assessing integrity of a target computer-based system. In one implementation, the power fingerprinting system may receive, at a first module, side-channel information of a first target component of a system, the first module being collocated with the first target component; obtain a power fingerprint for the first target component based on the side-channel information for the first target component, the power fingerprint for the first target component representing a plurality of execution statuses of the first target component; receive, at a second module, side-channel information of a second target component of the system, the second module being collocated with the second target component, the power fingerprint for the second target component representing a plurality of execution statuses of the second target component; and obtain a power fingerprint for the second target component based on the side-channel information for the second target component.
