摘 要
随着信息技术的快速发展，局域网环境下的数据安全问题日益凸显，传统的访问控制机制难以满足复杂网络环境下身份认证与权限管理的需求。为此，本文提出了一种基于身份认证的数据访问控制机制，旨在解决局域网中用户身份识别与数据资源保护之间的矛盾。该研究以局域网为背景，针对现有访问控制体系在身份验证、权限分配及动态管理方面的不足，引入了多因素身份认证技术，并结合属性基加密算法构建了一个全新的访问控制框架。通过建立用户身份特征库，实现了对用户身份的精准识别；利用属性基加密技术确保数据传输过程中的安全性；同时设计了灵活的权限管理系统，支持细粒度的访问控制策略。

Abstract
With the rapid development of information technology, data security in LAN environment is increasingly prominent, and the traditional access control mechanism is difficult to meet the needs of identity authentication and authority management in complex network environment. To this end, this paper proposes a data access control mechanism based on identity authentication, aiming to solve the contradiction between user identification and data resource protection in LAN. With the background of LAN, the research addresses the shortcomings of identity authentication, authority allocation and dynamic management of the existing access control system, introduces the multi-factor identity authentication technology, and constructs a new access control fr amework combined with the attribute-based encryption algorithm. By establishing the user identity feature library, realizing the accurate identification of user identity; using the attribute base encryption technology to ensure the security of data transmission; and designing the flexible permission management system to support fine-grained access control strategy.
