General IoT Security Landscape
The relentless growth of IoT devices introduces significant security challenges, including DDoS attacks, unauthorized access, and data manipulation. Traditional centralized security architectures struggle with the scale and heterogeneity of IoT environments, leading to single points of failure and privacy risks.
Blockchain's Role in IoT Security
Blockchain decentralizes trust, ensures data integrity, and provides transparent audit trails. Its immutable ledger prevents data tampering, while consensus mechanisms like Proof of Stake (PoS) and Proof of Authority (PoA) reduce reliance on central authorities, enhancing confidence and security in IoT interactions.
Integrated AI and Blockchain
The combination of AI and blockchain creates a robust security framework. AI subfields like Machine Learning (ML), Deep Learning (DL), Reinforcement Learning (RL), and Multi-Agent Systems (MAS) enhance anomaly detection, predictive analytics, and adaptive policy control. This synergy leverages blockchain's tamper-proof data provenance and AI's intelligence for real-time threat response.
AI/ML for Threat Detection
AI, particularly ML and DL algorithms, analyzes vast IoT data streams to identify anomalous behavior, predict, and counter security threats. ML models detect anomalies, intrusions, and malware. DL excels at recognizing intricate patterns, sophisticated threats like APTs and zero-day vulnerabilities, and predicting attacks by analyzing past data trends. Explainable AI (XAI) further enhances trust and understanding of these systems.
Real-World Applications
Case studies demonstrate the practical benefits of Blockchain-AI integration across various sectors. Examples like IBM Food Trust show enhanced supply chain transparency, while energy sector pilots (WePower-Elering) illustrate secure peer-to-peer energy trading and grid optimization. These applications highlight improved data integrity, provenance, and threat detection.

IBM Food Trust: AI-Powered Supply Chain Transparency
IBM Food Trust leverages a permissioned blockchain (Hyperledger Fabric) for supply chain transparency and traceability. AI analytics detect anomalies in environmental IoT sensor data (temperature, humidity, location), ensuring data integrity and provenance. This integration has resulted in a significant reduction in recall time from weeks to seconds and improved prediction accuracy. Challenges include the need for heavy standardization across diverse supplier systems and varying AI performance based on data quality.

BASIS: A Unified Integration Schema for IoT Security
The proposed Blockchain-AI Security Integration Schema (BASIS) offers a seven-axis taxonomy (Security Objective, Intelligence Modality, Trust Primitive, Placement & Execution, Scalability Enablers, Privacy & Safety Controls, Interoperability & Portability) to classify, evaluate, and guide the design of Blockchain-AI-IoT security solutions. This framework moves beyond descriptive review to actionable design, enabling interoperability, scalability, and privacy by design.
Future Research Directions for Enhanced IoT Security
Future research avenues include quantum-safe cryptography for robust encryption, hybrid on-chain/off-chain architectures for optimal performance, lightweight AI models for resource-constrained devices, federated learning for privacy-preserving distributed AI training, and the establishment of standardized frameworks to guarantee adoption and interoperability in complex IoT ecosystems.
