Works

Istok 2026–

A two-service load testing system for validating one-way data transfer through a hardware data diode. The sender generates and transmits test data; the recipient validates integrity, measures latency, and tracks packet loss — with no feedback channel between them, mirroring real diode constraints.

Supports five protocols across two groups: MQTT, TCP, and SFTP for bulk data transfer, and Modbus TCP / OPC UA for industrial telemetry (N machines × M indicators × F Hz). Each message carries a SHA-256 checksum and timestamp for end-to-end validation without a return path. Built as static musl binaries targeting Astra Linux SE.
