Hardware-Rooted Trust for Critical Infrastructure and Legacy Systems

Unspoofable sensor authentication using ARM TrustZone and ephemeral cryptographic binding. Designed for NIS2-essential entities: energy, transport, industry, and legacy financial systems.

THE CHALLENGE

Why Software-Only Authentication Fails Under Compromise

Industrial sensors rely on network-level security and software-based identity. Once an attacker gains network access — via compromised credentials, supply chain injection, or insider threat — sensor identity becomes trivial to spoof.

The result: false data injected into SCADA systems, undetected for months, with catastrophic consequences for safety, compliance, and operational continuity. This also applies to critical interfaces between legacy mainframe systems and modern environments in the financial sector.

NIS2 Directive (EU) 2022/2555 requires essential entities in energy, transport, and banking to demonstrate resilience against such compromise. Software-only identity does not meet this standard.

THE SOLUTION

Trust Anchored in Silicon, Not Software

SilicoTrust uses ARM TrustZone secure enclaves on industrial-grade microcontrollers (STM32L5, Nordic nRF9160) to generate ephemeral cryptographic identities that never exist outside the hardware boundary.

Ephemeral key generation: Keys exist only during attestation, eliminating static key exposure.
Hardware-bound identity: Sensor identity is cryptographically tied to the physical chip, not to firmware or network credentials.
Remote attestation: Verifiable proof of sensor integrity without trusting the network path.
Memory-safe firmware: Rust-based implementation eliminating memory corruption vulnerabilities at compile time.

The sensor cannot be spoofed. The key cannot be extracted. The identity cannot be cloned.

SYSTEM TOPOLOGY

Architecture: From Sensor to Verifier

"Data flows unencrypted through the network. Only the hardware-bound identity and signature are cryptographically protected. The verifier checks both data integrity and sensor authenticity without trusting the network path."

Secure Legacy Modernization

Secure modernization of COBOL/z/OS mainframe systems. We combine Rust offloading, patent-pending hardware-rooted ephemeral cryptography, and post-quantum crypto-agility to reduce MIPS costs, meet DORA/NIS2, and protect critical legacy-to-modern interfaces.

COMPLIANCE

NIS2-Aligned: Resilience Through Hardware Trust

NIS2 Directive (EU) 2022/2555 classifies energy, transport, banking, and other sectors as Essential Entities with mandatory cybersecurity requirements.

SilicoTrust addresses NIS2 Article 21 (cybersecurity risk management) and Article 23 (reporting obligations) by ensuring that sensor compromise is detectable within minutes, not months.

Risk management: Hardware trust boundaries reduce attack surface.
Incident detection: Spoofed sensors fail attestation immediately.
Reporting: Verifiable logs of sensor integrity for regulatory filing.

Note: NIS2 compliance is context-dependent. SilicoTrust is one component of a comprehensive cybersecurity program.

The team has built systems where a single vulnerability means operational shutdown — and designed architectures that prevent that vulnerability from existing in the first place.

FAQ

Technical Deep Dive

Traditional PKI binds identity to certificates stored in software or firmware. SilicoTrust binds identity to the physical hardware via ARM TrustZone. Even with full firmware extraction, the attestation key cannot be cloned to another chip.

No. SilicoTrust is a complementary layer for sensor identity. It integrates with existing PKI, SIEM, and SCADA systems via standard APIs and attestation protocols.

Currently STM32L5 (Cortex-M33 with TrustZone) and Nordic nRF9160 (Cortex-M33 + LTE-M/NB-IoT). Additional platforms on request for enterprise engagements.

SilicoTrust addresses NIS2 Article 21 (risk management) by adding hardware trust boundaries to sensor networks. It does not guarantee full NIS2 compliance, which requires a comprehensive program beyond sensor security.

Yes. The attestation is generated locally in the TrustZone secure enclave. Verification can occur asynchronously when connectivity resumes, using stored attestation logs.

Proof-of-concept: 2-4 weeks. Production integration: 8-12 weeks, depending on sensor network size and existing infrastructure.

Custom scope based on sensor count, network topology, and integration complexity. Typical engagements range from €15,000 (POC) to €50,000+ (production deployment). Contact us for a detailed quote.
