AEROSPACE & LEO

Radiation-Hardened
Entropy Sources

Space is hostile to analog electronics. Drift Systems provides a pure-digital entropy source that resists Single Event Upsets (SEUs) and operates reliably from -270°C to +125°C without shielding.


TEST RADIATION RESILIENCE

1. Single Event Upset (SEU) Simulator

Cosmic rays flip bits in silicon. Traditional CSPRNGs often "lock up" or require a full reset when their internal state is corrupted. Drift Systems uses Self-Healing Arithmetic to metabolize the error instantly.

SYSTEM A: STANDARD LFSR NOMINAL
Stream Integrity: 100%
SYSTEM B: DRIFT CORE NOMINAL
Stream Integrity: 100%

Observation: When you inject a fault, the Standard System detects the corruption and forces a "Safety Reset" (Downtime). The Drift Core absorbs the bit flip. Because the mapping $f(x)$ is strongly mixing, the error is diffused into valid noise in 1 cycle. No reboot required.

2. Space-Grade Capabilities

Thermal Stability

Analog TRNGs (Thermal Noise) fail in the vacuum of space due to extreme temperature swings (-270°C to +125°C). Drift is Pure Digital Logic, ensuring consistent entropy output regardless of ambient temperature.

Self-Healing Logic

As demonstrated, Drift does not require a "Watchdog Timer" to recover from SEUs. The chaotic attractor naturally pulls any perturbed state back into the high-entropy orbital path within nanoseconds.

Low SWaP (Size, Weight, Power)

With < 1000 Logic Cells and zero external components (no resistors/diodes), Drift integrates directly into existing FPGAs (Rad-Hard Xilinx/Microsemi), saving board space and weight.

Deep Space Telemetry

Secure the link to Voyager-class distances. Drift's deterministic nature allows for "Late Binding" key generation, ensuring that probes can re-sync with ground stations even after decades of silence.
