zeroRISC

OpenTitan-based silicon security platform

Overview

zeroRISC commercializes OpenTitan open-source silicon Root of Trust to deliver a full-stack security solution with silicon, software, and cloud services through the Integrity Management Platform. The platform verifies at boot that a device runs only authorized code, creating an immutable silicon fingerprint and letting owners enforce security policies via software rather than relying on manufacturers. It differentiates itself by offering end-to-end security tooling—silicon plus embedded OS and cloud management—rather than just supplying chips, targeting data centers, ICS/OT, IoT, and edge environments as an identity-as-a-service. The goal is to make foundational hardware security transparent and accessible, giving device owners centralized control and verifiable boot integrity across complex deployments.

Simplify's take

What believers are saying

  • June 2025 seed funding gives runway to push sales, integration, and hiring.
  • March 2026 PQC release aligns with NIST adoption and government procurement urgency.
  • Open-source silicon and below-OS lifecycle control match critical infrastructure compliance needs.

What critics are saying

  • No public 2026 customer wins means commercialization still depends on conversions, not technology.
  • Nuvoton and OpenTitan remain essential; any foundry or ecosystem shift stalls deployments quickly.
  • Intel, NXP, and proprietary RoT vendors can outspend zeroRISC and commoditize attestation.

What makes zeroRISC unique

  • ZeroRISC owns OpenTitan commercialization, from silicon to lifecycle management, not just IP.
  • Pavona delivered production-grade PQC, with 6–9x ML-KEM and ML-DSA speedups.
  • Board additions from Censys and Rockspring strengthen credibility with security and enterprise buyers.

ZeroRISC releases open-source post-quantum cryptography stack with 6–9x speed boost for silicon chips

ZeroRISC has released a complete open-source cryptographic hardware and software stack for both classical and post-quantum operations. The release includes the Cryptolib embedded cryptography library, an Asymmetric Cryptography Coprocessor, and hardware accelerators for symmetric operations. The multi-year collaboration with research institutions achieved 6–9x speedups for ML-KEM and ML-DSA algorithms whilst improving maximum operating frequency by 36–75% with near-zero area cost. Memory optimisations reduced ML-DSA stack usage by over 90%. Cryptolib supports classical algorithms including AES, SHA2/SHA3, RSA and elliptic curve cryptography, alongside NIST-standardised post-quantum algorithms ML-KEM, ML-DSA and SLH-DSA. The consortium will present results at Real World Crypto 2026 in Taipei on 9 March, demonstrating production-grade post-quantum cryptography for embedded systems.
