Ermm yeah. TEMPEST (as an acronym for Transient Electromagnetic Pulse Emanations Standard) has been around many decades and as such its mitigation by actors via various means. It is related to the RF emissions of hardware and ways to decode usable information from it. The name for this project is confusing. It uses TEMPEST characteristics to spot tampering. Which is an interesting use case in itself. They should've chosen another name. This will confuse the hell out of a lot of folks in this specific niche of infosec.
