Zero-Trust Hardware Architecture · Air-Gapped & Audit-Ready

Zero Cloud Exposure. Cryptographically Bound Edge Security.

Engineered from the silicon enclosure up for air-gapped defense perimeters, critical energy infrastructure and high-consequence enterprise facilities - where network breach and data persistence are non-starters.

Defense-in-depth architecture

Four layers. Every attack surface addressed.

How Chkdin AI removes attack surfaces across every layer of a deployment - from the network edge to the enclosure.

LAYER 01

Air-Gapped Sovereign Execution

Zero-WAN Topology

Architectural ControlChkdin AI edge nodes need no internet, cloud APIs or external SaaS connections to run inference, database matching or relay actuation.

✓ Attack Surface AddressedRemoves the cloud and WAN attack surface: cloud API hijacking, man-in-the-middle interception over the WAN, DNS spoofing and remote vendor backdoors.

Local Mesh IsolationMulti-node deployments communicate only over physically isolated facility VLANs, with mutual TLS (mTLS) node authentication.

LAYER 02

Volatile Memory Processing & Sub-50ms Zeroization

Zero Disk Footprint

Architectural ControlOptical RTSP and sensor frames are ingested directly into isolated volatile RAM buffers. The Proprietary Low-Latency Vision-AI Engine processes each frame in under 10 ms and overwrites the buffer within 50 ms.

✓ Attack Surface AddressedEliminates stored-footage risks: persistent video vulnerabilities, hard-drive theft and unauthorized extraction of surveillance footage.

One-Way Mathematical EmbeddingsAuthorized identity rosters are stored only as one-way mathematical vectors. Raw facial photographs are never stored and are not designed to be reconstructable from enclave memory.

LAYER 03

Hardware-Enclave Cryptographic Binding & Anti-Tamper

Integrated Neural Compute Core

Architectural ControlNeural models, runtime binaries and authorized vector rosters are cryptographically signed and bound to the unique hardware enclave keys of the Integrated Neural Compute Core.

✓ Attack Surface AddressedProtects against binary extraction, reverse engineering, model cloning and database dumping if an edge node is stolen or captured in the field.

Secure Boot & Signed FirmwareHardware-enforced secure boot verifies cryptographic firmware signatures before the node initializes, blocking unsigned code.

LAYER 04

Physical & Environmental Ruggedization

Field Resilience

Architectural ControlIndustrial-grade anodized aluminum chassis rated IP66 for dust-tight and high-pressure water-jet protection, with passive-fin thermal design for an operating range of -20°C to +65°C.

✓ Attack Surface AddressedProtects edge hardware against environmental degradation, dust ingress, thermal throttling and physical enclosure tampering.

Tamper-Evident EnclosureSealed enclosures make physical intrusion visible during routine inspection and audit.

Zero-persistence data pipeline

The life of one frame. Under 50 ms, then gone.

What happens to a single optical frame inside a Chkdin AI node - from capture to cryptographic zeroization.

STEP 01 Optical Capture RTSP / sensor frame

Frame arrives over the isolated facility VLAN.

STEP 02 RAM Buffer Ingest Volatile memory only

Written to an isolated RAM buffer - never to disk.

STEP 03 Neural Inference < 10 ms

On-Board Edge AI Accelerator Tier extracts the vector.

STEP 04 Enclave Match Encrypted roster

One-way vector compared inside the hardware enclave.

STEP 05 Local Action Relay / alert

Gate relay, alert or HUD update on the local mesh.

STEP 06 Zeroization < 50 ms · 0 KB

Frame buffer overwritten. Nothing persists.

Processed in volatile RAMZeroized · 0 KB written to diskNo WAN / cloud hop at any step

Where it is deployed

Built for high-consequence perimeters.

Defense Garrisons & Tactical Compounds

Hazardous Energy Refineries

Contractor access and hazard-zone tracking with no WAN dependency.

Megaproject EPC Corridors

Operator verification across remote, network-denied sites.

High-Security Convention Campuses

Delegate clearance and crowd telemetry on isolated venue VLANs.
