A Smart Contract for User Requests Based on ZKP in Fog Radio Access Networks

Abstract

Fog Radio Access Networks (F-RAN) offload computational processes to the network edge and transmit the processed results to the cloud, significantly reducing the load on cloud servers and improving service efficiency. While this architecture offers convenience, it inevitably raises severe privacy concerns. To address these issues, this paper proposes a blockchain-integrated F-RAN architecture. It employs smart contracts to ensure the security of user requests and introduces Zero-Knowledge Proof (ZKP) technology to minimize the frequent transmission of user private information across the network, thereby providing more effective privacy protection for users.
