Root of Trust (RoT)

Compact, Efficient, and Future-Ready Security

Open-source solutions like OpenTitan and Caliptra provide robust security features but often fall short in applications demanding minimal silicon area and ultra-low power consumption. FortifyIQ’s Root of Trust (RoT) overcomes these challenges with an innovative design that prioritizes compactness, efficiency, and unparalleled protections against Side-Channel Analysis (SCA) and Fault Injection Attacks (FIA).

Family of fully customisable Roots of Trust designed for a wide range of applications. All RoTs are hardened against side-channel and fault injection attacks, ensuring strong security even in highly constrained or hostile environments.

The portfolio includes specialized variants for IoT, cloud, chiplets, general-purpose (balanced), and edge AI, providing flexible integration and performance trade-offs to suit your system requirements. FortifyIQ RoTs are fully compatible with Caliptra and support both classical and post-quantum cryptography, enabling robust key management and on-the-fly encryption where applicable.

Addressing Key Pain Points:

  • Large Silicon Footprint: Open-source RoTs typically require significant silicon area, making them impractical for size-constrained devices.
  • High Energy Consumption: Existing solutions often consume excessive power, limiting their adoption in low-power environments like IoT devices.
  • Lack of Future-Proofing: Emerging security demands, such as Post-Quantum Cryptography (PQC), are frequently overlooked by current designs.

FortifyIQ’s Solution:

  • Optimized Design: A compact and power-efficient RoT, ideal for resource-constrained devices and advanced IoT applications.
  • Advanced Protection: Features integrated, state-of-the-art countermeasures against SCA and FIA, ensuring robust physical security.
  • Future-Proof Cryptography: Incorporates upcoming PQC algorithms, including Crystals-Kyber and Crystals-Dilithium, for resilience against quantum-era threats.
  • Seamless Integration: Enhances open-source platforms like Caliptra with unique physical attack protections and improved efficiency.

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.”
