摘 要
随着信息技术的迅猛发展，跨局域网的数据传输需求日益增长，但数据在不同网络环境下的安全传输面临诸多挑战。为此，本研究旨在设计并实现一种适用于跨局域网环境的数据安全传输协议，以保障数据传输的安全性、完整性和保密性。基于对现有安全传输协议的研究，提出了一种融合多层加密机制与身份认证技术的新协议框架。该协议采用非对称加密算法确保数据传输过程中的安全性，并引入基于数字证书的身份验证体系，有效防止非法访问和数据篡改。通过构建模拟跨局域网环境进行测试，结果表明新协议能够显著提高数据传输的安全性，在传输效率方面也表现出色，平均延迟时间较传统协议降低约20%，丢包率减少30%以上。此外，该协议具备良好的兼容性和扩展性，可适应多种网络架构。

Abstract
With the rapid development of information technology, the demand for data transmission across LAN is increasing, but the secure transmission of data in different network environments faces many challenges. To this end, this study aims to design and implement a secure data transmission protocol applicable to cross-LAN environments to ensure the security, integrity, and confidentiality of data transmission. Based on the research of existing secure transport protocols, a new protocol fr amework combines multi-layer encryption mechanism and identity authentication technology. This protocol adopts asymmetric encryption algorithm to ensure the security of data transmission process, and introduces the authentication system based on digital certificates to effectively prevent illegal access and data tampering. By building a simulated cross-LAN environment, the results show that the new protocol can significantly improve the security of data transmission, and also perform well in transmission efficiency. The average delay time is about 20% lower than the traditional protocol, and the packet loss rate is more than 30% lower. In addition, the protocol has good compatibility and scalability, and can adapt to a variety of network architectures.
