摘要
文章针对互联网环境下网络通讯信息的安全需求,研究了当前主流的加密技术及其在信息安全维护中的应用。通过分析对称加密、非对称加密及混合加密技术的原理与特点,构建了一种基于动态密钥管理的混合加密模型。实验采用KVM虚拟化平台模拟高并发网络环境,测试了AES、RSA及混合加密算法在加密效率、抗攻击能力和资源消耗等方面的性能。结果表明,对称加密算法AES在低负载下加密速度最快,但密钥分发存在安全隐患;非对称加密算法RSA安全性更高,但计算资源消耗较大;混合加密模型通过结合两者优势,在保障安全性的同时提升了加密效率,尤其适用于大规模数据传输场景。
This paper addresses the security requirements of network communications in the Internet environment by investigating current mainstream encryption technologies and their applications in information security.By analyzing the principles and characteristics of symmetric,asymmetric,and hybrid encryption techniques,this study constructs a hybrid encryption model based on dynamic key management.An experiment was conducted using the KVM virtualization platform to simulate a high-concurrency network environment,evaluating the performance of AES,RSA,and hybrid encryption algorithms in terms of encryption efficiency,resistance to attacks,and resource consumption.Results indicate that the symmetric encryption algorithm AES offers the highest encryption speed under low-load conditions,although key distribution poses security risks.The asymmetric encryption algorithm RSA provides higher security at the cost of increased computational overhead.The proposed hybrid encryption model integrates the strengths of both approaches,enhancing encryption efficiency while maintaining security,particularly in large-scale data transmission scenarios.
