LRAEB: Lightweight and Robust Anonymous ECC and Blockchain-Based Protocol for IoT in the Context of Public Cloud

Authentication is crucial in Internet of Things (IoT) networks as it ensures the integrity, accuracy, and tamper-resistance of information. This research article aims to design a lightweight and robust secure transmission system for IoT-enabled devices, enabling secure interaction with public cloud computing. The proposed system leverages blockchain technology integrated with elliptic curve cryptography (ECC), resulting in a resilient and efficient scheme tailored for resource and energy-constrained devices. We have adopted the SECP256K1 elliptic curve to design a Lightweight and Robust Anonymous ECC and Blockchain (LRAEB) scheme that offers superior performance. The use of blockchain guarantees the integrity and confidentiality of data stored in public cloud servers, addressing security vulnerabilities such as data leakage and unauthorized access. To validate the security of this novel technique, it will undergo verification using the Random Oracle Model (ROM) and Python. Our theoretical analysis confirms that the LRAEB scheme achieves better efficiency compared to existing schemes. In conclusion, we anticipate that this novel technique will significantly enhance information flow while mitigating the security flaws associated with public cloud computing and IoT devices.
