Abstract:

Blockchain technology has gained much interest because it can transform most industries through decentralisation, transparency, and security. Its most important application is in network security development, especially in the authentication process. Authentication is an important element of network communication, as it ensures the identity and security of users and devices against unauthorised access and exposure. In this study, the deployment of blockchain-based authentication into secure network communication has been researched. Real-world case examples, such as the blockchain platforms Ethereum and Hyperledger, were used as samples to investigate how blockchain-based authentication systems perform. Several performance metrics, including transaction throughput, call authentication time, and success rate, were compared in simulated testing. Python and Matplotlib programming languages were also employed to represent data graphically in the form of performance analysis and charts. The findings illustrate how systems that run on Blockchain are immune to common threats that exist in conventional authentication systems, such as man-in-the-middle attacks and password hijacking and perform optimally even under high loads. Comparative analysis is used in the research to quantify Blockchain against traditional methods in terms of latency, cost, and security. Because Blockchain is decentralised, the verification process is not susceptible to forgery and hacking; therefore, it is an ideal solution for secure network-to-network communication in financial, healthcare, and IoT applications. The outcome of this research also improves the architecture of safer and more resilient communication systems in our more networked world.
