The Mission Context

Secure mobility is not just about encryption — it’s about sovereignty. The ability to own, control, and verify every layer of your communications stack is the difference between operational assurance and strategic vulnerability.

The quantum era is not a distant horizon. NIST’s 2030 deprecation of RSA and ECC is a short runway in federal procurement terms. Cryptographically Relevant Quantum Computers (CRQCs) will render today’s public‑key encryption obsolete. Adversaries are already harvesting sensitive data now, intending to decrypt it later.

This is not an academic exercise. It’s a national security imperative.

The Strategic Risk

• Platform Dependence — iOS and Android are controlled by commercial entities outside U.S. Government authority. Their supply chains, firmware, and update channels are opaque.
• Metadata Exposure — Commercial carrier dependencies create unavoidable geolocation and traffic analysis risks.
• Procurement Lag — Federal acquisition cycles mean that if you start in 2030, you’re already too late.

From Secure Government Mobility to Purism: A Continuum of Mission-Grade Security

Past government programs proved that secure mobility for government missions requires more than strong encryption — it demands control. Control over the hardware, the software, the keys, and the operational environment.

Purism’s quantum‑resilient communications ecosystem builds on that same philosophy, but extends it into a future-proof architecture deployable at a national scale. It’s a working, field-ready system — not a lab demo:

Private 5G Networks (N79 Band)

• Fully isolated, customer-owned — no dependency on commercial carriers.
• Burnable SIMs for temporary, revocable access.
• No tower pings, no commercial geolocation tracking.

Post‑Quantum Cryptography (PQC)

• Implements ML‑KEM (FIPS 203) and AES‑256 — resistant to quantum attacks like Shor’s algorithm.
• Keys are device-bound and never transmitted.
• End-to-end confidentiality, even decades into the future.

Secure Hardware & Software Stack

• Multi-motherboard devices physically isolate radios, sensors, and compute.
• Linux-based OS with full source transparency.
• Locally controlled SIM burning and encryption modules.

Librem PQC/3926 Hardware Suite

• Encryptor, Comms Server, Admin Server.
• Up to 400 Gbps throughput.
• Secure tunneling — not just encrypted transmission.

Dynamic Spectrum Access & Dense Wavelength Division Multiplexing

• Flexible, high-capacity fiber and wireless.
• Low-latency rural and mobile deployments.

Zero Trust Architecture

• Every device in the network is verified and replaceable.
• No backdoors. No external key storage.

Why U.S. Government Customers Should Care

Today’s mobile ecosystem is dominated by iOS and Android platforms whose supply chains, firmware stacks, and update channels are controlled by commercial entities outside your direct authority. That dependency is a strategic liability.

Purism offers a sovereign alternative:

• Full Source Transparency — Every line of code is auditable, verifiable, and modifiable by cleared teams. No opaque binaries, no “trust us” security.
• Hardware Isolation by Design — Radios, sensors, and compute are physically separated, eliminating entire classes of remote exploitation inherent in monolithic smartphone architectures.
• On-Premise Key Ownership — All cryptographic material is generated, stored, and destroyed under your control — never escrowed, never exposed to vendor infrastructure.
• PQC‑Ready Mobility — Deployable secure devices that operate without tower pings or commercial carrier dependencies, enabling field teams to communicate without leaving a metadata trail.
• Lifecycle Sovereignty — From SIM provisioning to firmware updates, every operational layer can be brought in-house, ensuring compliance with U.S. Government security directives and supply chain integrity requirements.

Potential Applications

• Secure Overseas Communications — Deployable kits for encrypted mobile, satellite, and field operations.
• Critical Infrastructure Protection — PQC‑secured control systems for energy, agriculture, and transportation.
• Counter‑Surveillance — Devices that avoid tower pings and geolocation tracking.
• Post‑Quantum Readiness — Future‑proofing communications against CRQC threats.
• Data Sovereignty — Ensuring intercepted data remains indecipherable for decades.
• Sustainment & Maintenance — Secure field communications for depot-level support, remote diagnostics, and in-theater repair coordination, ensuring mission systems remain operational without exposing sensitive data.
• Common Operational Picture Integration — Compatibility with TAK and other COP software platforms for real-time situational awareness, blue force tracking, and mission planning in both connected and disconnected environments.
• Logistics & Supply Chain Operations — Encrypted coordination of materiel movement, inventory tracking, and mission resupply, with PQC-protected data flows from command centers to the tactical edge.
• Tactical Edge Deployments — Field-ready systems optimized for disconnected, intermittent, and low‑bandwidth conditions, enabling secure communications in austere or contested environments.

Compliance & Policy Alignment

• NIST PQC Standards — ML‑KEM and AES‑256 implementation.
• CNSSP‑15 — Meets Committee on National Security Systems Policy for mobility.
• NSA CSfC — Architecture aligns with Commercial Solutions for Classified layered security principles.
• Supply Chain Risk Management (SCRM) — Full transparency and control over hardware and software provenance.

Procurement Considerations

• Lifecycle Sovereignty — From provisioning to decommissioning, all processes remain under agency control.
• Interoperability — Can integrate with existing classified and unclassified networks.
• Scalability — Suitable for small tactical teams or national-scale deployments.

Closing Statement

The quantum clock is ticking. The choice is between building sovereign, post-quantum-ready communications now — or inheriting a compromised infrastructure later.

Purism’s architecture advances technically sound and strategically sovereign solutions. Our approach builds on the foundations of secure government mobility programs, integrating their principles and fortifying them with open, verifiable design

We’ve built our solutions so that no commercial carrier, no foreign jurisdiction, and no adversary — quantum or otherwise — can insert themselves between you and your communications.

Purism is not simply keeping pace — we’re running ahead.
