Critical Infrastructure: Resilient Cryptographic Protection for Vital Systems

Safeguarding energy, water, and transportation systems with certifiable hardware and software security

Critical infrastructure systems are becoming increasingly digital, networked, and vulnerable to cyber-physical threats, ranging from energy distribution and water treatment plants to rail control and emergency response networks. These environments require cryptographic solutions that are certifiable, resistant to physical attacks (SCA/FIA), and compatible with highly diverse embedded architectures.

FortifyIQ delivers software and hardware cryptographic solutions designed for the lifecycle demands of industrial infrastructure, enabling both secure greenfield deployments and retrofit protection for systems already in the field.

Why Securing Critical Infrastructure Is Complex

Long Lifecycle Equipment

Devices remain in use for decades, often with no hardware crypto support

Real-Time and Deterministic Performance

Security must not compromise timing or energy use

Diverse Hardware Platforms

RTUs, PLCs, industrial drives, and fieldbus-connected edge nodes

High-Value Targets

Attracting nation-state actors, ransomware, and sabotage

Why FortifyIQ ?

  • Built for Long-Term Resilience — FortifyIQ delivers certifiable cryptographic IP and software libraries resistant to side-channel and fault injection attacks, ensuring compliance with FIPS 140-3 Levels 3 and 4, SESIP Level 3 and higher, Common Criteria AVA_VAN.5, and IEC 62443 across energy, water, and transportation systems.
  • Technology-agnostic, implementation-agnostic, foundry-agnostic integration-ready cryptography — FortifyIQ’s soft macro IP integrates easily into industrial ASICs, SoCs, and FPGAs, offering the same high security with no reliance on special instructions, process nodes, or architectures, enabling seamless deployment across legacy (with software protection) and modern control platforms (with hardware protection).
  • Quantum-era readiness for national infrastructure — FortifyIQ’s IP cores include post-quantum protection (ML-KEM, ML-DSA), ensuring the long-term resilience of critical systems deployed today for decades to come.
  • Validation for Physical Threats — FortifyIQ’s in-house EDA tools (Side Channel Studio and Fault Injection Studio) enable thorough vulnerability testing pre- and post-silicon with published test results and SGS Brightsight validation supporting audit and compliance readiness.

FortifyIQ Solutions for Critical Infrastructure

Hardened Hardware & Software Cryptography

  • AES, HMAC, ECC/RSA, and PQC, all resistant to SCA and FIA, and certifiable under FIPS 140-3 Levels 3 and 4, SESIP Level 3 and higher, and Common Criteria AVA_VAN.5
  • Software libraries enable OTA upgrades for embedded systems that lack hardware accelerators.
  • Hardware IP cores optimized for minimal power, latency, and area, ready for industrial SoCs, MCUs, and FPGAs.

Validation & EDA Tools

  • FortifyIQ’s Side- Channel Studio and Fault Injection Studio enable validation during chip design.
  • They integrate with your functional verification workflows and existing testbenches.
  • They are used to eliminate vulnerabilities pre-silicon, pinpointing side-channel leakage to leaking modules and gates, and to confirm SCA/FIA resistance post-silicon.

Trusted Root-of-Trust and Cryptobox IPs

  • Secure boot, firmware updates, telemetry integrity, and key lifecycle enforcement
  • Flexible combinations of AES, HMAC, ECC/RSA, PQC, in customizable hardened Cryptobox IPs with exceptional power, performance, and area (PPA) metrics
  • Available as soft macros, technology-independent, and compatible with Caliptra/OpenTitan  architectures, with outstanding PPA

Assurance & Validation

FortifyIQ’s hardware IPs and software libraries undergo rigorous FPGA and simulation-based validation for side-channel and fault injection resistance, as well as in-silicon validation where applicable, ensuring compliance with the world’s most demanding physical security standards.

  • Side-Channel & Fault Injection Testing
    Designs are validated in-house using FortifyIQ’s proprietary Side Channel Studio and Fault Injection Studio, targeting timing, memory, and architectural leakage. After release, when relevant, our IP cores are validated and/or certified by third-party labs either as standalone blocks or integrated into complete secure chips
  • STORM-Based Validation
    FortifyIQ’s cryptographic protection using STORM (Small Table Oriented Redundancy-based SCA Mitigation for AES), a patented algorithm with a published formal security proof.
    Our AES design is mathematically proven side-channel resistant under STORM.
  • SGS Certification
    Our AES IP core was validated by SGS Brightsight against 30 million traces, and internally against 1 billion traces, with SGS confirming that the protection should hold for all IP cores using this hardened design.
  • Transparent Methodology
    FortifyIQ publishes its validation methodology and test framework to support customer certification.

Fortify’s AES security evaluation by SGS

“Summary. The leakage analysis (Welch t-test) on over 30 million traces did not show statistically significant first- and second-order differences between trace sets with fixed and random inputs. The template-based DPA analysis, on the pseudo-random trace set for the profiling phase (15 million traces) and on a sub-set of 300k fix input traces for matching phase targeting the first-round S-box output, and template attack on ciphertext, did not indicate any potential information leakage.”

” The results for the soft IP presented in the report were obtained on the TOE which is the basic hardware implementation of the soft IP without additional levels of security (e.g. that are present in a secure silicon layout). Therefore the internal strength of the soft IP itself was evaluated. This indicates that the investigated features and parameters of the soft IP implementation should be robust against SCA and fault injection attacks in different implementations including ASIC. Nevertheless, according to the Common Criteria rules, the strength of the final composite product must be evaluated on its own.”
