摘 要
随着无线网络技术的迅猛发展，无线局域网在各个领域的应用日益广泛，但其开放性也带来了诸多安全威胁，如非法接入、数据窃听和篡改等，严重影响了网络的安全性和可靠性。为此，本研究旨在深入探讨无线局域网的安全机制与优化方案，以提升其安全性。通过文献综述与理论分析相结合的方法，梳理现有安全机制的原理、特点及局限性，并基于此提出一种融合身份认证、加密传输和访问控制的综合安全框架。该框架不仅强化了用户身份验证过程，确保合法用户接入，还采用先进的加密算法保障数据传输安全，同时实施细粒度的访问控制策略，限制用户权限。实验结果表明，所提出的框架能够有效抵御多种攻击类型，在保证高安全性的同时，实现了较低的资源消耗和较好的用户体验。

Abstract
With the rapid development of wireless network technology, wireless LAN is increasingly widely used in various fields, but its openness also brings many security threats, such as illegal access, data eavesdropping and tampering, which seriously affects the security and reliability of the network. Therefore, this study aims to explore the security mechanism and optimization scheme of wireless LAN to improve its security. Through the method of combining literature review and theoretical analysis, the principles, characteristics and limitations of the existing security mechanism are sorted out, and a comprehensive security fr amework integrating identity authentication, encryption transmission and access control is proposed based on this. The fr amework not only strengthens the user authentication process to ensure legal user access, but also adopts advanced encryption algorithms to ensure the security of data transmission, and implements fine-grained access control strategies to limit user rights. The experimental results show that the proposed fr amework can effectively resist multiple attack types, achieving low resource consumption and better user experience while ensuring high security.
