Implantable devices are vulnerable to "Battery Drain" attacks. Drift Systems utilizes ultra-low power logic (nanowatts) to filter incoming commands, ensuring the main CPU only wakes for cryptographically valid requests.
Attackers can flood an IMD (Implantable Medical Device) with garbage requests. In standard systems, the CPU wakes up to verify (and reject) each packet, draining the battery. In Drift systems, the pre-CPU logic gate drops the packet instantly.
Observation: Under attack, Device A (Standard) flashes "CPU: WAKE" repeatedly, causing the battery to plummet (Red). Device B (Drift) keeps the CPU in "SLEEP" because the Drift Gate filters the noise before it hits the processor rail.
Our combinatorial logic gate operates on nanowatts. It verifies the incoming "Drift Sequence" before enabling the main power rail. This physically prevents attackers from exhausting the battery via RF flooding.
Medical wands (in-clinic programmers) establish a session-based drift state. This prevents "Drive-by" programming attacks or replay of previous adjustment commands, ensuring only the authorized physician can alter therapy.
Drift envelopes ensure that patient data (IEGM, Holter) is not spoofed or replayed. This prevents misdiagnosis caused by malicious injection of false cardiac rhythms into the monitoring backend.
Drift supports "Quorum-Based" override. In an ambulance, paramedics can utilize a specific "Emergency Drift" sequence that alerts the network but allows immediate therapy adjustment without cloud keys.
