Abstract : Internet of Things (IoT) has emerged as a leading technology involving an enormous number of entities. However, the complex nature of the IoT environment presents a rich surface for attackers to exploit its vulnerabilities and threaten its assets. The ownership of IoT devices is considered as one of the major assets, that is usually managed by centralized entities or Trusted Third Parties (TTP). IoT ownership is utilized to tackle some of the security requirements. Yet, relying on the centralized entity is a high risk as it can become the source of the attack itself. Hence, adopting the decentralized nature of blockchain technology might be the security game-changer, as it can potentially be utilized to manage the ownerships of IoT devices in a secure and decentralized manner without comprising central authorities or TTP. The primary focus of this thesis is to provide end-to-end trust in ownership management in which the data is consistent among all participants. Therefore, we propose an Ownership-based IoT security model using blockchain, called IoT of Trust. The proposed model relies on the smart contract, which is deployed onto an Ethereum blockchain network. IoT of Trust intends to handle the central authority issue by utilizing the blockchain capabilities with respect to trusted authenticity, origin, and permanent storage. It plays the role of controlling the ownership functions securely throughout the device lifecycle, as well as acquiring trusted logs of the device from the current owner back to the origin. The testing results demonstrate that IoT of Trust offers a significant degree of transparency, anonymity, immutability, and non-repudiation. In addition, the results of the evaluation reinforce the feasibility of the model’s performance in the IoT environment, as the average of the transaction fee for the main transactions is less than 1 USD/each. In addition, the average response time for calling the stored data is minimal, which is about 0.28 seconds.
