Defence communications are entering a transition window that will define how allied nations protect unmanned systems for the next two decades. At the 17th Annual NMIOTC Conference in Souda Bay, Crete, Delatr CTO Adrian Neal will present DQSP, the company's quantum-safe communications architecture designed for contested multi-domain environments across maritime, aerial, and autonomous platforms.

The conference theme, "Blue Resilience 360°: Securing Maritime Infrastructure in the Era of Multi-Domain Operations," addresses exactly the operational reality Delatr was built for: environments where GPS is denied, RF links are jammed, platforms are captured, and adversaries are recording encrypted traffic today for decryption tomorrow.

Why drone communications security is a procurement problem, not a research problem

The quantum threat to defence communications is no longer speculative. NIST has set a clear timeline: RSA and ECC will be deprecated by 2030 and disallowed entirely by 2035. The UK's National Cyber Security Centre has published a three-phase migration roadmap targeting full post-quantum cryptography adoption by 2035, with high-priority upgrades expected between 2028 and 2031. The NSA requires national security systems to adopt quantum-resistant cryptography for new acquisitions starting in 2027.

These are not distant deadlines. Defence procurement cycles run 10 to 20 years. A drone platform procured today will still be in operational service through the 2030s and into the 2040s, well past the point where the cryptographic foundations it launched with will have been formally deprecated.

This creates a straightforward commercial problem: any unmanned system bought now with classical encryption baked into its communications stack will need an expensive retrofit within its operational lifetime. The integration work, requalification burden, and programme risk of that retrofit will fall on the OEM, the integrator, or the operator. Whoever builds quantum-safe communications into the architecture from day one avoids that cost entirely.

What Delatr is presenting at NMIOTC

Adrian Neal's presentation focuses on how Delatr's quantum-safe communications architecture addresses the specific operational conditions that maritime and autonomous systems face in contested environments. The key areas of discussion include post-quantum secure communications for unmanned systems, resilient command and control in contested RF environments, continuous rekeying and compromise containment, and secure maritime infrastructure in the era of autonomous operations.

What distinguishes Delatr's approach from a standard post-quantum cryptography retrofit is the class of security guarantee. Most PQC solutions, including NIST-standardised algorithms like Kyber and Dilithium, provide computational security: they are secure because the underlying mathematical problems are believed to be hard. If those assumptions break, so does the security.

Delatr's architecture achieves bounded information-theoretic security. For the protected traffic class, there is provably nothing to break. This is the same category of guarantee as a one-time pad, delivered without the operational burden of distributing pad-length keys to every platform in the field.

The operational realities that shaped the architecture

Maritime and autonomous operations impose constraints that most enterprise cryptography was never designed for. Bandwidth is scarce. Power budgets are tight. Links are intermittent. Platforms operate in denied, disrupted, and contested electromagnetic environments where every kilobit of radio chatter competes with mission traffic.

Delatr's architecture was designed around these constraints. The encryption core is implemented as a deterministic, pipelined function that imposes a steady low-energy load rather than the bursty compute spikes associated with public-key handshakes. Keys rotate at network tempo, not handshake tempo, which means mission-critical traffic, including flight commands, override authority, and sensor tasking, is protected with near-continuous rotation that handshake-based cryptography cannot sustain over a tactical link.

Compromise containment is built into the architecture at the platform level. Each platform carries its own isolated key reservoir. Capturing one drone reveals nothing about the rest of the fleet. Compromise is contained to metadata leakage alone. This is not an add-on capability: it is a structural property of how the system generates and manages keys.

For GNSS-denied operations, the security layer continues operating independently of GPS availability. The encryption and authentication functions have no dependency on positioning infrastructure. Navigation may fall back to platform autonomy, but command-and-control integrity is unaffected.

The conference and who will be there

The NMIOTC 17th Annual Conference brings together military, law enforcement, industry, and academic professionals to discuss the protection of critical maritime infrastructure in the context of multi-domain operations. The conference panels cover the new maritime operating environment, multi-domain awareness from seabed to space, the role of industry as a security partner, and the policy frameworks shaping resilient maritime ecosystems.

Delatr will be joining organisations including NATO, NATO Maritime Command, NATO Allied Joint Force Command Norfolk, the European External Action Service, NATO School Oberammergau, the Institute of Innovation and Knowledge Exchange, SpaceTime Industries, Coventry University, and Stellenbosch University. The conference brings together professionals from across the alliance working on the operational, policy, and technology dimensions of maritime security.

What this means for OEMs and integrators

The audience at NMIOTC includes the people who make procurement decisions about the communications stacks inside unmanned platforms. For OEMs and defence integrators, the question is not whether quantum-safe communications will be required, but whether they will be designed in from the start or retrofitted later at significant cost and programme risk.

Delatr's Lineage product is a software security layer that sits between the flight controller and the telemetry radio. On the air side, a lightweight compute module installs inline between the flight controller UART and the telemetry radio with no changes to flight controller logic or radio firmware. On the ground side, a software layer installs on the ground control station between Mission Planner or equivalent GCS software and the ground telemetry unit.

This architecture is deliberately designed to reduce adoption risk. OEMs do not need to redesign their stacks. Integrators do not need to replace radio hardware. Operators do not need to change their flight control workflows. The security layer protects the communications path while preserving the systems that customers already use.

The compliance clock is running

Allied nations are converging on PQC compliance deadlines across overlapping timelines. Australia targets 2028. The UK and Europe are working toward 2030 to 2031. Canada has set a 2031 target. NIST's deprecation of RSA and ECC by 2030, with full disallowal by 2035, creates a hard procurement wall that affects every defence programme with a communications component.

For unmanned systems, the timeline is even tighter. Platforms procured in 2026 and 2027 will be operational through the mid-2030s. If the communications security baked into those platforms relies on classical cryptography, operators will face a mandatory mid-life retrofit at exactly the point when compliance deadlines are binding and quantum-capable adversaries may already be active.

Building quantum-safe from day one is not a technology decision. It is a procurement risk decision. That is the conversation Delatr is bringing to NMIOTC.
