Methods and apparatuses for validating supply chain for electronic devices using side-channel information in a signature analysis

A method, comprising:

• sending, to a target device, a first signal associated with a set of codes to be executed by the target device;
• receiving first side-channel information associated with the target device in response to the target device executing the set of codes, the first side-channel information including a temperature of the target device while executing the set of codes;
• determining second side-channel information associated with a simulated device in response to the set of codes, the second side-channel information associated with a temperature of the simulated device;
• comparing a discriminatory feature of the first side-channel information with a discriminatory feature of the second side-channel information to determine an origin of a foundry of circuits of the target device;
• and
• sending, to a user interface, a second signal that identifies the origin of the foundry of the circuits of the target device.

An apparatus, comprising:

• a memory having a database configured to store a plurality of characteristics associated with a simulated device including foundry information for the simulated device;
• and
• a processor coupled to the memory,
• the processor configured to send, to a target device, a first signal associated with a set of codes to be executed by the target device;
• the processor configured to receive first side-channel information associated with the target device in response to the target device executing the set of codes;
• the processor configured to determine second side-channel information associated with the simulated device in response to the set of codes;
• the processor configured to identify foundry information for the target device as corresponding to the foundry information for the simulated device when a discriminatory feature of the first side-channel information substantially matches a discriminatory feature of the second side-channel information;
• and
• the processor configured to store, in the database, the foundry information for the target device.
