FortiTrust

Hardware Root of Trust

What Is FortiTrust?

FortiTrust provides a complete, high-assurance hardware Root of Trust (RoT) framework built on FortifyIQ’s intrinsically secure cryptographic engines. It delivers secure boot, key management, attestation, and lifecycle controls with exceptionally high PPA efficiency.

These fully customizable Roots of Trust are designed for a wide range of applications. They are hardened against side-channel and fault injection attacks, ensuring strong security even in highly constrained or hostile environments, or where insider attacks are a threat. The portfolio spans variants optimized for IoT, cloud, chiplets, balanced designs, and edge-AI, providing flexible integration and performance scaling to match system needs.

FortiTrust RoTs operate as a fully standalone Roots of Trust, and are also compatible with Caliptra for flexible integration. They support classical and post-quantum cryptography for secure key management and on-the-fly encryption. They deliver all of Caliptra’s security benefits while avoiding its practical drawbacks, such as the large area footprint, rigid configuration, and integration complexity of the reference implementation. They support Caliptra‑compliant integration flows while delivering outstanding PPA in the cryptography module, making the root of trust suitable for a wide range of devices and silicon designs.

FortifyIQ Differentiators for RoT

Caliptra‑compatible, delivering all the benefits of Caliptra while avoiding its overhead, with dramatically smaller area, simple per‑device configuration, and outstanding PPA

Security Boutique, including tuning for the device’s optimal PPA balance, and optional radiation-induced fault hardening for high-altitude systems. Customization is flexible up to tape-out.

Built on FortiCryptoBox cores (AES, HMAC, PKA, PQC)

Minimal area and power despite full-featured secure services

Compliance-ready, certifiable at the highest security levels, with full documentation supporting FIPS 140‑3, Common Criteria AVA_VAN.5, SESIP/PSA-class RoT requirements, and post-quantum readiness, streamlining audits and formal certification.

Configurable to customer requirements (boot modes, key hierarchy, PPA)

Soft-macro & node-agnostic

Validated high assurance in internal lab, via FortiEDA, showing robust resistance to side-channel and fault injection attacks

Unified API across software and hardware for AES, HMAC, ECC/RSA, and PQC, enabling seamless migration between SW and HW implementations without changing the security stack, preserving secure‑boot, attestation, key‑management, and lifecycle flow

Secure OTA updates for asymmetric cryptography, allowing updates to ECC, RSA, and PQC parameter sets, protection mechanisms, and newly standardized algorithms

AVA_VAN.5 Evaluation & Validation Summary
SGS Brightsight Common Criteria Laboratory
“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”
