TEMPEST Emanation Security

Every piece of switching electronics — a monitor cable, a keyboard matrix, a CPU bus — leaks a faint electromagnetic ghost of the data moving through it. Military and government systems defend against this with TEMPEST/EMSEC doctrine: certified Faraday shielding, distance separation and strict Red/Black cable discipline. This simulator renders a protected system radiating real inverse-square-law emanation pulses inside a 3D scene, then lets you tune shielding effectiveness, eavesdropper distance and clock frequency, plus flip on the single failure mode that defeats a shielded enclosure outright — an unshielded I/O cable exiting the boundary — while live readouts compute received power, reconstruction correlation and the reliable intercept range from the governing radio-propagation formula.
