    BKRSC-IoT: Blockchain-Based Key Revocation Using Smart Contracts for IoT Networks
    (Springer, Cham, 2024-02-02) Bettayeb Sami; Messai Mohamed Lamine; Hemam Sofiane Mounine
    The growth of Internet of Things (IoT) networks has brought the crucial need for information and communication security to the fore. Since IoT devices exchange sensitive data, secure key management with its different phases and the key revocation phase especially is essential for IoT network security. However, existing IoT key management solutions need improvements because of the resource limitations of IoT devices. Despite considering these limitations, current key revocation solutions have several areas for improvement, including the high communication overhead of the limited-resource devices. Therefore, there is always a need for a decentralized and efficient solution to address these issues in IoT networks. This paper presents a new solution for key revocation based on Blockchain using smart contracts to minimize the communication overhead and the energy consumption in IoT networks. Furthermore, we assess the correctness of the proposed solution through security and performance analysis. The results show that our solution has reduced the communication overhead by 93,55%, 91,87%, and 99,75% compared to other solutions during the compromising, leaving, and draining cases, respectively, which proves that our solution is efficient and appropriate for IoT networks.
