Nexus Gatekeeper: Edge Verification Runtime (Simulation)

Deployment Target: ARMv8 (Cortex-A53 / Hivemapper Bee)
Status: Functional Simulation (BEE-ARM-A53-X99)
Objective: Pre-ingest filtering to reduce cloud ingest and reward leakage by ~15–20%.

⚡ Overview

Nexus is a lightweight edge-resident gatekeeper designed to run alongside dashcam firmware. It validates physical motion consistency before mapping data enters the upload pipeline.

Threat Model: Low-effort GPS spoofing using desk-bound simulators (constant velocity, zero vibration).

Mitigation Strategy: Correlate GNSS-reported velocity with real-time IMU vibration entropy. If physical motion does not match claimed motion, the data packet is dropped locally.

Fail-Closed Guarantee: If the Nexus process halts or loses heartbeat, the upload pipeline is disabled. No unsigned or unverified data can enter the network.

Runtime output distinguishing IDLE states, validated drives (green), and simulator spoofing (red).

🏗️ Architecture: Verify_Motion_Correlation()

Nexus enforces a deterministic physical consistency check:

1. GNSS Velocity Check: Evaluate claimed speed against a motion threshold (>10 km/h).
2. IMU Entropy Check: Measure vibration RMS and entropy from accelerometer data.
3. Decision Gate: If speed exceeds threshold while vibration remains below the configured floor, the packet is blocked locally.

# Simplified Logic
if gps_velocity_kmh > 10.0:
    if imu_vibration_grms < VIBRATION_THRESHOLD_G:
        upload_allowed = False
        status = "BLOCKED (SPOOF)"

🛠️ Hardware Footprint (ARM Cortex-A53)

Designed for safe coexistence with primary mapping workloads:

• CPU Overhead: <2% sustained (single core @ ~1.2 GHz)
• Memory Footprint: ~35 MB RSS
• Security Model: Production builds are designed to bind session material to ARM TrustZone or a secure element. Keys are not intended to reside in user-accessible memory.

🚀 Simulation Quickstart

The simulation cycles through three states: Real-world driving, Simulator-based spoofing, and Idle / GPS drift.

# Run on Linux / WSL
