Abstract
With the rapid advancement of wireless network technology, its applications in daily life and industrial fields have become increasingly extensive. However, the accompanying security threats have also become more severe. This paper focuses on the critical issues of authentication and encryption technologies in wireless networks, aiming to explore and propose effective solutions to enhance the security of wireless communications. Based on the current mainstream wireless network protocol fr amework, this study analyzes the vulnerabilities of existing authentication mechanisms and encryption algorithms when facing novel attacks and proposes an improved solution that integrates multi-factor authentication with adaptive key management. By constructing an experimental environment to validate the proposed method, the results demonstrate that this scheme can significantly reduce the risk of unauthorized access while improving the confidentiality and integrity of data transmission. Furthermore, this paper innovatively introduces an anomaly detection model based on machine learning for real-time monitoring of network behavior and dynamic adjustment of security strategies, thereby enhancing the robustness of the system. The primary contribution lies in proposing a comprehensive protection mechanism that balances efficiency and security, providing new research directions and technical references for the field of wireless network security, with significant theoretical value and practical application implications.
