Decentralized Secure Data Sharing for Mobile Edge Computing Using Blockchain

Mobile Edge Computing (MEC) is a promising technology that provides high bandwidth and low latency for mobile users. However, it raises significant security challenges, particularly in ensuring the secure transfer of sensitive user data across subnetworks. This paper presents a blockchain-based key management scheme for MEC that enhances security and trust in dynamic mobile environments. The proposed approach allows mobile devices to communicate securely by encrypting data with public keys stored on the blockchain, ensuring efficient key management and mitigating potential attacks. Theoretical analysis demonstrates improved security, while experimental results validate the scheme’s efficiency and scalability.
