Abstract

This study addresses the challenge of securing smart-home Internet-of-Things (IoT) systems under severe resource constraints by proposing and evaluating a lightweight hybrid framework that couples on-device anomaly detection (TinyML) with elliptic-curve cryptography (ECC) and blockchain-based event logging. The approach first classifies incoming sensor readings locally using a TinyML anomaly detector (Isolation Forest); normal data are then encrypted with ECC and transmitted, while all security relevant actions  are immutably recorded on a blockchain ledger to provide auditability and device trust. The framework was implemented on a smart home dataset of 49,000 records. The TinyML model achieved strong detection performance (0.98 Precision, 0.97 Recall, 0.975 F1-score, 0.996 Accuracy). Cryptographic and logging overheads were small average ECC key generation in 5.12 ms, encryption 0.85 ms, decryption 0.82 ms and blockchain logging. Overall, the results indicate that combining on device anomaly detection with ECC-secured communication and tamper-evident logging can deliver end-to-end protection, transparency, and scalability for smart-home IoT.
