Industrial Cybersecurity
Secure by Design
Cybersecurity at the heart of engineering
The AEM-60DC8 ships with cybersecurity built into the firmware. Every layer — boot, update, telemetry — is engineered for environments where shop-floor control must never be compromised.
Signed Firmware (Ed25519)
Ed25519 digital signature with our own domain-separation prefix. Master key in hardware (Yubikey) with up to 4 rotation slots.
9-Layer Boot Validation
Before accepting an image: magic word, version, CRC, hw_id, size, payload, vector table, end seal, signature.
Persistent Anti-Rollback
TAMP counters with battery backup. Survive reset and power cycle. Saturate at 65,535.
Anti-Brick by Construction
The bootloader lives in a flash region the update channel never touches. Validation failure = update mode, never bricking.
Forensic Telemetry
Post-incident without cable, cloud or PII. Reset, HardFault, RTOS health, NACK reasons — all over Modbus.
