摘 要
随着电子商务的迅猛发展，网络交易安全成为亟待解决的关键问题。本研究聚焦于计算机安全协议在电子商务中的应用，旨在构建一个全面的安全保障体系，确保交易过程中的信息保密性、完整性和不可抵赖性。通过分析SSL/TLS、SET等主流安全协议的工作原理及应用场景，结合实际案例探讨其在支付网关、身份认证、数据加密等方面的具体实现方式。研究发现，基于公钥基础设施（PKI）的安全协议能够有效防范网络攻击，提升交易安全性；同时提出一种融合多因素认证与智能合约技术的创新方案，显著增强了用户身份验证的可靠性和交易流程的透明度。实验结果表明，该方案不仅提高了系统的抗攻击能力，还优化了用户体验，为电子商务平台提供了更加完善的安全保障机制，对推动我国电子商务健康发展具有重要意义。

Abstract
With the rapid development of e-commerce, the security of online transactions has become a critical issue that urgently needs to be addressed. This study focuses on the application of computer security protocols in e-commerce, aiming to construct a comprehensive security fr amework that ensures confidentiality, integrity, and non-repudiation during transactions. By analyzing the working principles and application scenarios of mainstream security protocols such as SSL/TLS and SET, this research explores their specific implementations in payment gateways, authentication, and data encryption through practical case studies. The findings indicate that security protocols based on Public Key Infrastructure (PKI) can effectively prevent network attacks and enhance transaction security. Furthermore, an innovative solution integrating multi-factor authentication and smart contract technology is proposed, which significantly improves the reliability of user authentication and the transparency of transaction processes. Experimental results demonstrate that this solution not only increases the system's resistance to attacks but also optimizes user experience, providing a more robust security mechanism for e-commerce platforms. This research holds significant implications for promoting the healthy development of e-commerce in China.
