Summary:
Ensuring cybersecurity resilience in far-edge IoT devices remains a significant challenge as these systems often lack dedicated hardware security elements such as TPMs or secure enclaves. This paper introduces a cost-effective SRAM PUF-based RoT architecture tailored for resource-constrained devices enabling secure authentication and local attestation without relying on persistent key storage. Leveraging a commercially available SRAM module and a syndrome-based fuzzy extractor the proposed framework enables robust and unforgeable key reconstruction while a lightweight KDF binds the device identity to device-specific system properties (dynamic or static) thereby providing attestation capabilities in resource-constrained environments. A realistic telehealth monitoring scenario involving an ECG device and a trusted gateway demonstrates the feasibility of deploying the solution in real-world use cases. Extensive benchmarking results validate the low overhead of cryptographic operations and trustworthiness evidence extraction highlighting the practicality of the proposed approach for scalable resilient far-edge infrastructures.Author(s):
