Abstract

With the rapid development of information technology, the security threats faced by communication networks have become increasingly complex and diverse, revealing the limitations of traditional security mechanisms in new types of attacks. Blockchain technology, characterized by its decentralization, immutability, and cryptographic algorithms, offers a novel solution to enhance the security of communication networks. This study aims to explore the application of blockchain technology in communication network security to improve the overall security and reliability. By analyzing typical security challenges in communication networks and integrating the core principles of blockchain technology, this research proposes a blockchain-based communication network security fr amework. This fr amework leverages blockchain's distributed ledger technology to ensure the integrity and authenticity of data transmission, employs smart contracts for automated security policy management, and utilizes consensus mechanisms to guarantee stable system operation. Experimental results demonstrate that the proposed blockchain-based security fr amework can effectively resist various types of network attacks, such as data tampering and identity impersonation, while not significantly increasing system overhead. Innovatively integrating blockchain technology with communication networks, this study not only provides new approaches to addressing communication network security issues but also expands the application prospects of blockchain technology in other fields, contributing significantly to the advancement of more secure and reliable communication networks.
