Context & Background

Cross-Domain Security

A data diode is the only acceptable interface when data leakage from a sensitive network to the outside world is not an option. Industry standards mandate physical unidirectionality — the reverse path is severed at the hardware level, not via software.

Hardware-Enforced Unidirectionality

Absence of reverse TX/RX lines — a physical hardware guarantee.

TEMPEST-Compliant Design

Mandatory protection against compromising electromagnetic emanations.

Complete Galvanic Isolation

Galvanic isolation partitioning the two security zones.

THE INDUSTRY PROBLEM

The 'Fire-and-Forget' Flaw in Legacy Systems

Legacy data diodes transmit packets over fiber with no way of knowing whether the data actually reached its destination or was corrupted along the way.

Silent Data Loss
Unverifiable Data Integrity
The Operator is Left Blind
System Architecture

Two FPGAs, one direction,
full control.

Internal communication between the two boards runs strictly over fiber optics, in one direction only, with full galvanic isolation. Acknowledgment loops are local to each side — never across the fiber. The optical core stays strictly unidirectional.

Differentiator 02 — Delivery Guarantee

Segmented End-to-End Delivery Guarantee

STEP 01 · TRANSMIT

Proprietary FEC-Enhanced UDP

Packets leave the upstream board with hardware-enforced Forward Error Correction (FEC). No TCP overhead, no software network stacks.

STEP 02 · BUFFER

Decoding & Buffering

The downstream FPGA decodes the FEC, automatically repairs errors, and holds the packet in its buffer until acknowledgment.

STEP 03 · ACK & RETRY

Application-Level Acknowledgment

The receiving application confirms delivery. Upon a missing ACK, configurable retransmission is triggered, providing a true delivery guarantee.

Defense in Depth

Four Independent Layers of Protection

Layer 1: Hardwired Logic

The entire operation is implemented exclusively within the FPGA logic. With no processes, system files, or command interpreters, the software attack surface is completely eliminated.

Layer 2: Dual-Board Air Gap

Two physically separate FPGA boards with independent power supplies. Electrical compromise of one board cannot propagate to the other.

Layer 3: Tamper Protection

Active sensors protect against physical tampering. Any unauthorized attempt to open the chassis triggers the instant erasure of cryptographic keys and configuration data.

Layer 4: EMSEC & TEMPEST Compliance

Advanced shielding against side-channel electromagnetic radiation leakage — a mandatory requirement for deployment in highly secure government and military environments.

Integration & Config API

No OS, But Not a "Black Box" — Total Control

Unlike legacy data diodes that rely on restrictive DIP-switches or offer almost no configuration at all, the DDF-10G/UNI exposes a comprehensive API for networking, monitoring, and policy management — all without introducing an operating system.

Network Parameter Configuration

Dedicated management channel for secure IP, MAC, and VLAN orchestration.

Granular Retransmission Policies

Configurable retry limit per stream / application.

Multi-Flow & QoS

Multiple logical channels multiplexed over a single physical link.

Telemetry & Auditing

Hardware counters: packet tracking, retry attempts, and corrected FEC errors.

Deployment Scenarios

When 'fire-and-forget' simply isn't an option.

Military & Government Sectors

Secure transfer of classified data to lower-trust analytics networks, maintaining absolute separation of the sensitive High-Side domain.

Critical Infrastructure

Streaming OT/SCADA telemetry to corporate IT networks with zero exploitable return paths. Energy, oil & gas, water, and transportation.

Banking & Finance

Replicating transactional data to back-office or analytics systems with zero risk of compromise.

Healthcare

Exporting medical imaging and patient data between networks with differing compliance tiers (such as HIPAA and GDPR).

Aerospace & Telecommunications

Secure data downlink from high-integrity control systems to commercial processing platforms.

R&D & Advanced Research

Exporting experimental results from an isolated laboratory with zero risk of Intellectual Property (IP) exfiltration.

Value Proposition

Why Choose DDF-10G/UNI?

01

The Only Data Diode Combining Full Management with an Isolated ACK Loop

Competitors only offer 'fire-and-forget' delivery. We deliver true end-to-end confirmation via a segmented ACK loop, configurable hardware retransmission, and live telemetry — all without sacrificing physical, hardware-level unidirectionality.

02

Immune to OS-Level Attacks (OS-Less Architecture)

No Linux, no shell, no patch management. Completely immune to OS-level CVE exploits — the entire operation is hardwired into the FPGA logic.

03

Hardware-Grade Deterministic Performance

Native 10 Gbps line-rate speed with constant, schedulerless latency. Hardware FEC repairs errors instantly, eliminating wasteful retransmissions over the physical fiber.

The Bottom Line

A data diode that operators don't just 'deploy and forget.' Instead, they actively monitor, configure, and audit it — all while fully preserving the hardware-guaranteed unidirectionality.
