Securing IoT Identities Against Advanced AI Threats
The growing deployment of the Internet of Things (IoT), especially in critical infrastructure, has increased the need for identity systems that are scalable and robust against attacks. Existing centralized systems have fundamental weaknesses, particularly against AI-based adversarial techniques like generative spoofing, model poisoning, and deepfakes. This paper introduces a novel blockchain-based IoT security system that integrates decentralized identity verification, zero-knowledge proofs (ZKPs), Byzantine-resistant federated learning, and formal verification of smart contracts. This architecture aims to eliminate single points of trust, enhance privacy during device registration, and provide a multi-layered defense against AI-driven attacks through formally modeled state transitions. Experimental results demonstrate significant improvements, including a 48% reduction in false acceptance rate during GAN-based spoofing and a speedup in ZKP verification, offering a robust identity management system for IoT that balances performance and security.

Decentralized Identity (DID) in IoT
Adversarial Robustness in FL
Formal Verification of Smart Contracts
Behavioral Biometrics and Deepfake Resistance
Traditional centralized identity systems are inadequate for IoT platforms due to their reliance on trusted third authorities and limited scalability, making them single points of failure. Blockchain-based DID models offer self-sovereign identity (SSI) and verifiable credentials. This system leverages DIDs for secure device identification without revealing sensitive information, ensuring verifiable device credentials and protection from unauthorized access. The immutable identity binding prevents identity spoofing or Sybil attacks.

Federated learning (FL) enables collaborative model training across distributed nodes without raw data sharing, but is susceptible to adversarial attacks, especially model poisoning. Robust aggregation methods like Krum are used to isolate malicious gradients. The proposed system integrates Byzantine-resistant federated learning to ensure secure AI model aggregation and verification, specifically using the Krum algorithm for its effectiveness against adaptive attacks and minimal tuning requirements.
| Method | Key Features | Limitations in AI-driven Attacks | Relevance to Proposed System |
|---|---|---|---|
| Krum Algorithm |
|
None (chosen for its robustness) | Core for secure AI model aggregation and verification in IoT. |
| Homomorphic Encryption (Yazdinejad et al.) |
|
Computational overhead, specific attack vectors not fully covered. | Supports privacy and data confidentiality in FL. |
| Dynamic Gradient Filtering (Colosimo and De Rango) |
|
May not be sufficient against highly adaptive AI attacks. | Helps refine gradient handling, but Krum is primary. |
| Statistical Robustness (Daukantas et al.) |
|
Complex to implement for all AI attack types. | Contributes to overall system verification principles. |

Smart contracts are crucial for automated execution in blockchain systems but can contain logic errors and exploits. Traditional verification tools often lack interoperability and scalability for complex contracts. This system employs formal verification using Manticore, a symbolic execution engine, to systematically analyze logical correctness, state transitions, and execution paths of smart contracts. This ensures contracts behave as expected, preventing vulnerabilities exploitable by AI agents.

Behavioral biometric methods are gaining popularity for user verification, analyzing patterns like typing style and screen touch to distinguish genuine users from attackers. The system incorporates behavioral biometrics as a proactive security measure against AI-driven threats such as deepfake UI phishing, using cosine similarity to compare live behavior with saved profiles. This enables multi-factor authentication or access blocking if scores fall below a threshold.
