摘 要
随着信息技术的迅猛发展，局域网在企业、机构等内部信息交互中发挥着不可替代的作用，但数据传输过程中的安全威胁日益严重。为保障局域网内数据的安全性，本研究聚焦于数据安全加密技术在局域网传输中的应用，旨在探索有效的加密方案以抵御潜在风险。通过对比分析对称加密与非对称加密算法的特点，结合局域网实际环境需求，提出一种融合两种加密方式优势的混合加密机制，并引入基于身份的密钥管理策略优化传统密钥分发流程。实验结果表明，在该加密机制下，数据传输过程中未出现信息泄露情况，且加密解密效率满足局域网实时性要求。

Abstract
With the rapid development of information technology, LAN plays an irreplaceable role in the internal information interaction such as enterprises and institutions, but the security threat in the process of data transmission is increasingly serious. In order to ensure the security of data in LAN, this study focuses on the application of data security encryption technology in LAN transmission, and aims to explore effective encryption schemes to resist potential risks. By comparing and analyzing the characteristics of symmetric encryption and asymmetric encryption algorithm, combined with the actual environment requirements of LAN, a hybrid encryption mechanism integrating the advantages of two encryption methods is proposed, and the identity-based key management strategy is introduced to optimize the traditional key distribution process. The experimental results show that under this encryption mechanism, there is no information leakage situation during the data transmission process, and the encryption and decryption efficiency meets the real-time requirements of LAN.
