Designing energy-efficient authenticated encryption pipelines capable of running within tight thermal budgets inside the brain.
Biological tissue is exceptionally sensitive to localized heat: sustained temperature increases exceeding 1.0°C cause cellular apoptosis. NeuroHSM achieves sub-microwatt power consumption by leveraging event-driven asynchronous logic that sleeps between neural spike bursts.
With emerging neural probes featuring 1,024 to 10,000 distinct recording sites, NeuroHSM utilizes hardware delta-compression and lightweight authenticated encryption (ASCON) to stream 100 Mbps telemetry across wireless cranial transceivers.
