Defense and Aerospace: Mission-Critical Security at Every Altitude

Protecting secure communications, critical systems, and advanced AI with certified resistance to physical attacks

The Defense and Aerospace sectors demand cryptographic solutions that are certifiable, tamper-resistant, and future-proof, capable of protecting everything from secure field radios and satellites to AI-based targeting and avionics control systems. These systems often operate in adversarial environments where physical access, side-channel attacks (SCA), and fault injection (FIA) are real threats.

FortifyIQ delivers software and hardware cryptographic solutions designed to meet the highest levels of assurance, for both newly developed systems and deployed platforms needing secure upgrades. Our hardened cryptographic IP cores, software libraries, roots of trust, and EDA tools are engineered to secure mission-critical data across air, land, sea, space, and cyber domains.

The Security Challenges in
Defense and Aerospace

Real-World Adversaries

Devices are often deployed in contested environments and must remain secure even when physically captured or tampered with, protecting keys, algorithms, and mission data.

Legacy Systems in Need of Modern Protections

Military and aerospace platforms are often expected to remain in use for decades. Many have no hardware security features, yet must meet today’s strict cryptographic assurance levels. OTA-upgradable, physically hardened software libraries are one of the only viable ways to retrofit secure cryptography into legacy equipment.

Secure AI and ML at the Edge

From autonomous drones to radar systems and tactical AI engines, AI must be protected against model theft, inference manipulation, and reverse engineering. FortifyIQ's EDA tools and crypto IPs defend AI models against physical extraction and runtime compromise.

Post-Quantum Threats

Nation-state adversaries are preparing for the quantum era. Cryptographic systems in defense must be quantum-safe now, and hardened against both algorithmic and physical threats.

Compliance and Certification

Defense systems must meet a range of international and national security standards, including:

  • FIPS 140-3 Levels 3/4 (cryptographic modules)
  • Common Criteria AVA_VAN.5 (resistance to physical attack)
  • NSA Commercial Solutions for Classified (CSfC)
  • DO-326A / DO-356A for aviation cybersecurity
  • NATO, NIST, and EU NIS2 guidance

Why FortifyIQ ?

FortifyIQ delivers hardened cryptographic IP, software, and EDA tools designed to meet the mission-critical security, integration, and compliance demands of aerospace and defense platforms, including radiation tolerance. Side-channel and fault injection protection for industry-specific applications, can also be provided by request.

FIPS 140-3 (Levels 3 and 4), Common Criteria AVA_VAN.5, DoD APL and NIAP-aligned

Proven SCA and FIA resistance with formal security proofs and rigorous TVLA validation up to 1 billion traces in hardware, and verified no-leakage software against over 100K TVLA traces

Minimal power, latency, and area overhead, ideal for radiation-hardened SoCs, secure processors, and low-SWaP systems

Delivered as soft macros (synthesizable RTL), portable across ASICs, FPGAs, and mixed-technology platforms

Technology-, implementation-, and foundry-agnostic, our algorithmic cryptographic protection applies equally in any silicon process or system architecture

Highly configurable to mission-specific requirements, support for custom profiles, tuning for PPA, and integration into non-standard architectures

No custom instructions or nonstandard integration paths: FortifyIQ crypto cores integrate like any standard cryptography IP core

Defense-grade secure boot and attestation, with hardened Roots of Trust and crypto cores for trusted computing environments, optimized for minimal latency and area, designed for constrained platforms like field radios and tactical drones

PQC support for long-lifecycle threat protection, including ML-KEM and ML-DSA for future-proofed defense applications

For In-House Development, FortifyIQ’s Pre- and Post-Silicon Validation Tools, Side-Channel Studio and Fault Injection Studio, help eliminate vulnerabilities before deployment. These EDA tools validate physical attack resistance across execution timing, routing, memory, and submodules.

 AES IP cores include:

RAMBAM, which is validated to Common Criteria AVA_VAN.5 by SGS Brightsight. TVLA-compliant with over 1 billion traces validations, meeting and far exceeding regulatory standards.

STORM: Formally proven side-channel security with minimal power consumption. TVLA validated against over 15 million trace-validation. See the STORM scheme’s security proof here.

HMAC-SHA2 IP cores include:

HMAC-SHA2: Based on a patented variant of the security-proven Threshold Implementation (TI), validated to meet the highest cryptographic regulatory standards (and TVLA validated on over 100 million traces).

Compact-Fast HMAC-SHA2: Validated to 100 million traces against the known attacks. 

Our validation methodology includes:

  • Pre-silicon RTL validation using FortifyIQ’s EDA tools (TVLA, gate-level trace, attack simulation)
  • FPGA and post-silicon testing
  • Protection against DPA, CPA, EMA, and fault injection (e.g. voltage, EM, clock)
  • Detection of non-invasive fault injection

After release, and when relevant, our IP cores are validated and/or certified by third-party labs either as standalone blocks or integrated in complete secure chips.

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.”
