Sovereign integrity for every flight, every sensor, every command.
Modern airframes, satellites, and uncrewed platforms rely on dozens of suppliers and millions of lines of firmware. A single tampered telemetry packet or unsigned override can put a mission — or a crew — at risk. DPSM places a hardware root of trust in silicon and seals every state transition into an immutable chain.
Where Aerospace & Defense breaks today
Telemetry spoofing & GPS denial
Unsigned sensor streams can be replayed or substituted in flight, leading flight controllers to act on fabricated data.
$10B+ — annual GNSS-spoofing damage estimate · GPS World, 2024
Unauthorized override channels
Vendor maintenance backdoors and admin bypass paths remain a leading vector for kinetic compromise of avionics.
78% — of avionics CVEs traced to bypass paths · GAO, 2023
Supply-chain firmware tampering
OTA updates from tier-2 and tier-3 suppliers reach the airframe with limited cryptographic provenance.
ITAR · DFARS — controls now require tamper-evident logs end-to-end
Three patents, deployed against this industry's threat model
Each of Axowl's three filed patents maps to a specific structural failure mode in Aerospace & Defense. Together they form a single, end-to-end defense.
Hierarchical Distributed Trust Fabric — Sensor (L1) · Avionics (L2) · Ground + Satellite (L3) quorum
PUF-derived identities are embedded in each sensor (L1), echoed by the avionics computer (L2), and reconciled with the ground station and a redundant satellite link (L3). Loss or capture of any single subsystem does not expose the system key — kinetic actions require k-of-n agreement across tiers, so a compromised line-replaceable unit cannot, by itself, execute a release.
Transition-Sealed Integrity System — Black-box-grade sealing of every control transition
Every flight-control deflection, weapons-release authorization, and telemetry frame is sealed at the moment it crosses a state boundary. The hash chain preserves both the time and the actor; investigators can reconstruct the precise sequence of events with cryptographic certainty, even when the airframe is recovered weeks later.
Pre-grant LLM Conflict Verification — Pre-grant blocking of conflicting flight authorities
Before a permission such as "ground crew + weapons hot" or "co-pilot + autopilot override in restricted airspace" is granted, the LLM gate detects the semantic conflict and refuses the grant itself. The unsafe combination never reaches the cockpit, eliminating an entire class of insider and procedural risk.
Deployment that fits the threat model
Mission criticality and regulatory exposure (DFARS, ITAR, CMMC 2.0) push aerospace deployments to the Iron tier — hardware-only, FPGA PUF, with custom ASIC integration on the production glide path.
Recommended tier: T3 · Iron
Deployment path: AWS F2 (FPGA) → MPW prototype → ASIC mass production
Operational detail: Initial integration runs on AWS F2 within 72 hours for ground systems and simulator hardware. Airborne hardware moves to MPW prototype on 8-inch wafer, then to commercial mass production via Korean foundry partnerships (DB HiTek HV BCD for harsh environments).
Three concrete deployments
UAV swarm command authority
Each airframe carries a PUF-bound identity. A spoofed drone cannot join the swarm because it cannot produce a valid k-of-n signature; rogue commands are dropped at the radio layer.
Satellite firmware OTA
Updates are sealed by the manufacturer's L1 device and re-sealed at L2 ground stations. The satellite refuses to boot any image whose chain does not terminate at the original PUF root.
Black-box reconstruction
Post-incident, every actuator command and every authorization is reconstructible with cryptographic timestamps, replacing weeks of forensic interpretation with a deterministic timeline.
Versus what's deployed today
Today — Traditional avionics signing
Centralized signing keys held by ground operators; firmware updates rely on supplier honesty. A single key extraction compromises an entire fleet.
With DPSM — Axowl DPSM
PUF keys never leave silicon. Even Axowl staff cannot extract them. Per-airframe, per-sensor identity makes fleet-wide compromise mathematically impossible.
