However, IIoT architectures face significant challenges, including centralized control, vulnerability to cyber attacks, privacy violations, and data accuracy issues. These challenges create significant obstacles in securing data, which is crucial for the growth of this technology. To address these issues, many researchers suggest integrating blockchain technology as a stable means to safeguard data within IIoT systems. Blockchain’s features of distributed storage, decentralization, and immutability offer distinct advantages in data secure storage, identity verification, and access control. Despite these benefits, as IIoT applications diversify and data scales expand, the high resource demand of blockchain systems clashes with the limited resources of IIoT devices, leading to unresolved contradictions and persistent issues within this solution. Existing blockchain architectures still lack anonymous and efficient IIoT identity authentication, with complex encryption and decryption processes inducing excessive system overhead. To address these issues, the thesis builds on prior research to optimize blockchain performance, aiming to resolve the shortcomings and bottlenecks in current blockchain-based IIoT architectures regarding data security protection. Firstly, this thesis introduces a lightweight blockchain-enabled protocol designed for secure data storage in the dynamic IIoT environment. It incorporates bilinear mapping for system initialization, entity registration, and authentication technology to authenticate IIoT entities efficiently and securely, along with an off-chain data storage approach to ensure data integrity with reduced resource consumption. Furthermore, the thesis addresses the limitations of Hyperledger fabric systems in high availability scenarios by proposing Trie-Fabric, which enhances transaction processing through a Directed Acyclic Graph (DAG) based transaction sorting algorithm. This approach significantly reduces terminated transactions, optimizes conflict handling, and increases efficiency by more than 60% in its best case, according to comparative experimental results. To manage the increasingly sophisticated industrial processes and privacy-sensitive data generated by IIoT devices, the thesis proposes a smart contract-assisted access control scheme utilizing the Attribute-Based Access Control (ABAC) model. This scheme, supported by bloom filter components, demonstrates controlled contract execution times, stable system throughput, and a rapid consensus process in real-world simulations, making it highly capable of handling high-throughput and effective consensus even under large-scale request scenarios. Lastly, the thesis introduces the Zero-Knowledge Proof (ZKP) algorithm, which integrates a non-interactive zero-knowledge proof protocol with Ciphertext-Policy Attribute-Based Encryption (CP-ABE) to enhance security and efficiency in IIoT content distribution. Combined with the Distributed Publish-Subscribe IIoT (DPS-IIoT) system using Hyperledger fabric, it significantly improves bandwidth efficiency and overall throughput in IIoT environments. Through comprehensive security performance evaluations and experimental results, this research confirms the protocols’ effectiveness in minimizing system overhead, improving storage reliability, and enhancing overall IIoT data management and application security. This thesis provides an in-depth examination of advanced data management protocols and systems for the IIoT, which are crucial for advancing the manufacturing sector. Consequently, this work makes a significant contribution to the field of IIoT data security, offering scalable and robust solutions for current and future industrial systems.<\/p>\n","protected":false},"excerpt":{"rendered":" L’Ecole doctorale : Ecole Doctorale de l’Institut Polytechnique de Paris et le Laboratoire de recherche SAMOVAR – Services r\u00e9partis,
