基于AES的车联网通信加密算法

Cryptographic Algorithm of IoV Communication Based on AES

随着V2X技术发展得越来越快,车辆与其他设备的通信量以及信息重要度都在急速增长,车载信息遭到攻击从而被截取或者发生泄漏的风险也相应地大大增加,因此信息交互安全性成为了一个不可避免的研究课题。本文针对车联网传输数据量大、数据加解密操作频繁等问题,通过分析经典加密算法,进而改进传统AES加密算法,使用RC4加密算法生成伪随机密钥代替AES加密算法的密钥生成模块,优化加密时间的同时提升安全性能,并开展实验验证了其加密效率以及安全性。

As V2X technology develops rapidly,the volume of communication between vehicles and other devices,as well as the importance of information are growing rapidly,and the risk of in-vehicle information being attacked,intercepted or leaked has also increased accordingly,so the security of information interaction has become an unavoidable topic.Addressing the issues of large data volume and frequent data encryption and decryption operations in vehicle networking,this paper analyzes classical en‐cryption algorithms and improves the traditional AES-based encryption algorithm.By using the RC4 encryption algorithm to gen‐erate a pseudo-random key instead of the key generation module of the AES encryption algorithm,the encryption time is opti‐mized,and security performance is enhanced.Experiments are conducted to verify encryption efficiency and security.
