Unbreakable Security Chain for MCU Software
From compile time to runtime — an unbreakable chain. Unauthorized hardware access blocked at the architectural level. Not detected. Prevented.
Verified on STM32F103 · ARM Cortex-M · RISC-V
The Hidden Risk in Embedded Systems
Software in your devices has unrestricted hardware access. One bad update can brick a device, corrupt data, or be exploited.
Unauthorized Access
Software can read and write any hardware register without restriction. No boundaries.
Silent Failure
Faulty code continues running undetected. Field impact invisible until it's too late.
Uncontrolled Updates
OTA updates can run without valid signatures or outside defined policies.
Prevention, Not Detection
IGL ECO defines what hardware a module can touch at compile time — and enforces it all the way to runtime. Nothing outside the defined effect set can happen. Architecturally impossible.
Structural Prevention
Blocked at architecture level, not at runtime
End-to-End Chain
Compile → Package → Verify → Runtime, no gaps
Hardware Independent
No TrustZone or MPU required. Works on existing MCUs
Auditable Evidence
Every compile automatically produces an effect report
Code breaks through barriers
Code stopped at first gate
An Unbreakable Chain Across 4 Phases
Software Analysis
Code inspected before execution. Effect set created. Sensor software cannot touch motor control.
Secure Package
Code + policy + limits sealed under one cryptographic signature. Policy cannot be weakened.
Device Verification
Device verifies before executing. Corrupt or unsigned packages are rejected. Fail-closed.
Runtime Enforcement
Every hardware access compared to the effect set. Access outside the list is deterministically blocked.
Where IGL ECO Applies
Smart Meters & Energy Infrastructure
Remotely-delivered firmware updates run only within permitted hardware zones. Unsigned or policy-violating updates are rejected before execution.
Industrial Control & IIoT
Logic modules update independently without reflashing the runner. Motor control and sensor access remain isolated by policy.
Long-Life IoT Devices
10+ year field devices update logic safely without bricking risk. Certification evidence artifacts generated automatically.
