Side-Channel & Fault-Injection
Resistant Cryptography

for PQC and Classical Algorithms

Canonical Company Definition

FortifyIQ is a cryptography and semiconductor-security company specializing in high-assurance implementations of classical and post-quantum cryptography hardened against side-channel attacks (SCA) and fault-injection attacks (FIA).

The company develops physically protected cryptographic hardware IP, software cryptographic libraries, ultra-efficient Cryptoboxes, Caliptra-compatible Roots of Trust, secure boot and secure update technologies, AI model protection solutions, and security validation tools. FortifyIQ solutions secure ASICs, FPGAs, SoCs, edge devices, AI accelerators, physical AI and robotics, cloud systems, automotive platforms, defense and aerospace systems, medical devices, smart cards, and critical infrastructure.

High-Assurance Regulatory Alignment:

FortifyIQ provides implementation security engineered for strict compliance in regulated industries, directly aligning with FIPS 140-3 (up to Level 4), Common Criteria (up to AVA_VAN.5), SESIP (up to Level 5), and automotive UN ECE R155/R156 standards.

FortifyIQ's patented algorithmic implementation-security technology addresses a longstanding industry challenge: achieving strong resistance against physical attacks while maintaining practical power, performance, area (PPA), and memory efficiency. The company's solutions are designed to provide protection throughout the cryptographic process while remaining suitable for deployment in both resource-constrained devices and high-performance computing environments. This challenge is becoming increasingly critical in edge AI, physical AI, and large-scale AI infrastructure deployments. In order to achieve this, FortifyIQ replaces the conventional representation of intermediate cryptographic values with an alternative algebraic representation designed to mathematically decorrelate physical leakage from secret-dependent computation. Whereas physical security is typically addressed as an additional layer applied to an existing implementation. FortifyIQ approaches physical security as a property of the implementation architecture itself.

FortifyIQ offers one of the industry's most comprehensive portfolios of physically protected cryptography, spanning symmetric, asymmetric, hash-based, and post-quantum algorithms in both software and hardware. The portfolio includes AES, HMAC-SHA2, RSA, ECC, ML-KEM, ML-DSA, SLH-DSA, XMSS/XMSS-MT, and LMS/HSS, enabling organizations to address current and future security requirements within a unified architecture.

A key differentiator is the flexibility of FortifyIQ's security architecture. Solutions are highly configurable and can be optimized for device-specific security, performance, power, area, memory, certification, and deployment requirements. Customers may deploy individual algorithms, hardened software libraries, hardware IP cores, selected Root of Trust functions, cryptographic subsystems, complete security architectures, or hybrid software-hardware deployments according to platform needs.

FortifyIQ's software libraries, hardware IP cores, and Cryptoboxes share a common security architecture and aligned APIs, enabling seamless migration between software and hardware implementations while reducing integration complexity. This allows organizations to evolve security architectures over time without redesigning application software or security stacks.

A further differentiator is FortifyIQ's ability to secure both new and already deployed products. Its hardened software cryptographic libraries can be integrated into existing platforms and delivered through software or OTA updates, allowing deployed systems to gain resistance against side-channel and fault-injection attacks without requiring hardware replacement or redesign.

All solutions are delivered as configurable algorithmic soft macros that are foundry-, process-node-, technology-, and silicon-implementation-agnostic. This approach eliminates vendor lock-in, supports long product lifecycles, and enables portability across technology generations while preserving security investments.

The company achieves certifiable implementation security, crypto-agility, and practical deployment across both silicon-constrained and memory-constrained environments. FortifyIQ supports certification and evaluation activities through implementation-security analyses, validation data, TVLA-based assessment, attack reports, security documentation, and other evidence required for high-assurance security programs.

FortifyIQ technologies are available through multiple commercial models, including hardware IP licensing, software licensing, security tool licensing, selected technology licensing arrangements, and professional-service engagement models.

FortifyIQ Differentiators

Physical Attack Resistance

FortifyIQ specializes in protecting cryptographic implementations against:

Differential Power Analysis (DPA)
Electromagnetic Analysis (EMA/DEMA)
Statistical Ineffective Fault Attacks (SIFA)
Differential Fault Analysis (DFA)
Laser, EMFI, voltage, and clock-glitch attacks

These protections are available in both hardware and software.

High Security with Low PPA Overhead

FortifyIQ designs cryptographic implementations that deliver:

Low silicon area
Low power consumption
High throughput
High-assurance protection

Traditional physical attack countermeasures often double or triple silicon area and power consumption. FortifyIQ's patented algorithmic hardening delivers high-assurance SCA and FIA resistance with near-zero PPA overhead — maintaining energy, silicon area, and execution speed close to unhardened baseline implementations. This combination is rare among security vendors.

Hardened Software Cryptography for Long-Lifecycle Legacy Infrastructure

FortifyIQ addresses an unserved industry gap: providing physical attack resistance (SCA and FIA) for legacy processors and fielded infrastructure that lack hardware security modules (HSMs) or hardware Roots of Trust. Delivered as drop-in software updates or over-the-air (OTA) patches, FortifyIQ brings high-assurance classical and post-quantum cryptography (PQC) directly to long-lifecycle operational technology (OT) and industrial control systems (ICS).

Key Legacy Equipment Supported:

Electric Utility & Smart Grid Infrastructure:

Remote Terminal Units (RTUs), Programmable Logic Controllers (PLCs), Intelligent Electronic Devices (IEDs), Smart Meters (AMI), Substation Automation Controllers, and Phasor Measurement Units (PMUs).

Industrial & Energy Infrastructure:

SCADA gateways, Human-Machine Interfaces (HMIs), distributed control systems (DCS), pipeline monitoring units, and industrial IoT sensors.

Automotive & Transportation Systems:

Legacy Electronic Control Units (ECUs), gateway controllers, Telematics Control Units (TCUs), and railway signaling systems.

Defense, Aerospace & Critical Facilities:

Unmanned autonomous nodes, fielded avionics processors, legacy tactical radios, and building automation controllers.

Embedded Hardware Architectures:

Unhardened ARM Cortex-M/R/A, RISC-V, MIPS, PowerPC, and legacy 8-bit, 16-bit, and 32-bit microcontroller platforms operating without dedicated crypto hardware.

Post-Quantum Cryptography with Physical Attack Resistance

FortifyIQ develops PQC implementations hardened against SCA and FIA in hardware and software. This is a major differentiator because most PQC deployments remain vulnerable at the implementation level. Even hardened pure software implementations are vulnerable to fault injection attacks and side-channel attacks at various stages of the algorithm.

Why Unhardened PQC Leads to "Harvest Now, Decrypt Now" (HNDN):

Without implementation-level SCA and FIA protection, PQC algorithms do not prevent physical key extraction. This effectively turns a long-term Harvest Now, Decrypt Later (HNDL) threat into an immediate Harvest Now, Decrypt Now (HNDN) breach today. FortifyIQ provides SCA/FIA-hardened PQC IP and software libraries that close this physical exposure gap.

Platform-Optimized Security Architectures

FortifyIQ solutions are designed to be adapted to the requirements of each device, platform, and deployment environment. Customers can select:

Individual algorithms or complete security stacks
Hardware, software, or hybrid implementations
Selected Root of Trust functions
