Decentralized Authentication in Wireless Mobile Networks Using Blockchain

The rapid proliferation of wireless mobile networks has necessitated robust and scalable authentication mechanisms to ensure secure communication and user privacy. Traditional centralized authentication systems, while effective, are increasingly vulnerable to single points of failure, scalability issues, and privacy concerns. This paper explores the potential of blockchain technology to enable decentralized authentication in wireless mobile networks. By leveraging the inherent properties of blockchain—such as immutability, transparency, and distributed consensus—we propose a novel framework that eliminates the need for a central authority, thereby enhancing security and resilience. The proposed system utilizes smart contracts to automate authentication processes, ensuring tamper-proof and efficient user verification. Additionally, the decentralized nature of the framework mitigates risks associated with data breaches and unauthorized access. Through a combination of theoretical analysis and simulation-based experiments, we demonstrate the feasibility and advantages of blockchain-based decentralized authentication in terms of security, scalability, and performance. The results indicate that this approach not only addresses the limitations of traditional systems but also paves the way for more secure and privacy-preserving authentication in future wireless mobile networks.
