Design and Comparison of Hardware Architectures for FIPS 140 Certified Cryptographic Applications

This study presents a systems-oriented comparative analysis of hardware architectures designed to implement cryptographic functions certified under the FIPS 140 standard. As organizations increasingly rely on interconnected digital infrastructures, cybersecurity has become a key enabler of sustainable systems management and organizational competitiveness. The research evaluates a representative set of secure hardware solutions—ranging from low-cost IoT modules (Microchip ATECC608B/C) and TPM 2.0 chips to advanced embedded platforms (NXP SE050 + i.MX 8X), enterprise HSMs, and cloud-based systems (AWS Nitro Enclaves). A multi-criteria framework is applied, integrating certification level, cryptographic performance, physical protection, ease of integration, and total cost of ownership as part of a holistic systems-engineering assessment. Results demonstrate clear trade-offs between performance, scalability, and assurance: while enterprise HSMs and cloud enclaves offer superior throughput and compliance (FIPS 140-3 Level 3), their cost and complexity challenge wide deployment. Conversely, lightweight secure elements provide affordable and compliant protection suitable for large-scale IoT and edge environments. By aligning cryptographic architecture design with principles of systems management and process optimization, this study provides actionable insights for improving the resilience, reliability, and competitiveness of modern digital infrastructures.
