摘 要
随着信息技术的迅猛发展，网络已成为现代社会不可或缺的基础设施，但网络故障频发对数据安全传输构成严重威胁。为此，本研究聚焦于网络故障下的数据安全传输协议，旨在构建一种高效、可靠且具备容错能力的数据传输机制。通过分析现有网络故障类型及其对数据传输的影响，结合密码学理论与分布式系统原理，提出了一种基于冗余路径和加密校验的混合式传输协议。该协议在传统TCP/IP协议基础上进行改进，引入多路径选择算法以规避故障节点，并采用轻量级加密算法确保数据完整性与保密性。实验结果表明，在模拟多种典型网络故障场景下，所提协议能够有效降低丢包率，提高传输成功率，平均传输时延较传统方法减少约30%，同时保证了数据的安全性。

Abstract
With the rapid development of information technology, network has become an indispensable infrastructure in modern society, but frequent network faults pose a serious threat to data security transmission. To this end, this study focuses on the data secure transmission protocol under network failure, aiming to build an efficient, reliable and fault-tolerant data transmission mechanism. Based on the analysis of existing network failure types and their influence on data transmission, combining cryptography theory and distributed system principle, a hybrid transmission protocol based on redundant path and encryption verification is proposed. This protocol is improved on the basis of the traditional TCP / IP protocol, introducing a multi-path selection algorithm to avoid fault nodes, and using a lightweight encryption algorithm to ensure data integrity and confidentiality. The experimental results show that in the simulation scenario, the proposed protocol can effectively reduce the packet loss rate, improve the transmission success rate, reduce the average transmission delay by about 30% compared with the traditional method, and ensure the data security.
