Identification of dual processes using power side-channels

Malware is one of the main threats against electronic devices, as malicious software can damage the device, disrupt network communications and provide an entry point for additional attacks. Software-based countermeasures such as anti-virus can be effective but they require presence on the device and can furthermore be disabled or fooled by advanced malware. Monitoring of physical side-channels, on the other hand, provides a non-invasive and hard-to-spoof method to detect unauthorized software being executed on a device.
