METHODS AND APPARATUSES FOR VALIDATING SUPPLY CHAIN FOR ELECTRONIC DEVICES USING SIDE-CHANNEL INFORMATION IN A SIGNATURE ANALYSIS

摘要

Some embodiments described herein include a method to validate supply chains for electronic devices using side-channel information in a signature analysis. The method includes sending, to a target device, a first signal associated with a set of codes to be executed by the target device, and then receiving first side-channel information associated with the target device in response to the target device executing the set of codes. The method also includes determining second side-channel information associated with a simulated device in response to the set of codes. The method further includes comparing a discriminatory feature of the first side-channel information with a discriminatory feature of the second side-channel information to determine a characteristic of the target device based on a pre-determined characteristic of the simulated device. Finally, the method includes sending, to a user interface, a second signal associated with the characteristic of the target device.
