Full RoT Subsystems Don’t Fit Constrained SoCs

Most root of trust solutions assume you have silicon area to burn.

If you’re designing a constrained IoT, edge or automotive ECU, a heavyweight RoT blows your gate budget before you’ve added application logic.

And bolting on an external TPM adds cost, board space and a new attack surface.

QRoot Lite — Security with Silicon Overhead

QRoot Lite delivers secure boot, measured attestation, sealed storage and key management in under 25,000 gates. Immutable hardware design, side-channel protected by design, and built to the TCG MARS specification.

Integration guidance and compliance documentation included.
From security architecture to and tape-out, expert support through every stage of silicon development including system certification.

Ultra-Small Footprint

<25K gates — designed from the ground up for area-constrained SoCs, MCUs, sensor nodes and chiplets. No bloat, no compromise.

Ascon Lightweight Crypto

Co-designed with BIT/TCG. NIST lightweight cryptography standard — purpose-built for constrained environments.

Immutable & Side-Channel Protected

Hardware-based measurement and attestation that can’t be modified by software. Side-channel resistance built into the architecture.

Built For Security-Critical Silicon

Proven silicon IP and embedded software, built for real world scenarios.
