基于AES的车联网通信加密算法OACSTPCD

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.
