Abstract: In the process of the intelligentization and networking of the Internet of Vehicles (IoV), the security issue is increasingly important. As the core technology and basic support to ensure the security of IoV, cryptography plays an irreplaceable role in data encryption and identity authentication. In China, the cryptographic application is still in the infancy. In this paper, we introduce the commercial cryptographic algrithms, relevant standards, and how to ensure the safety with the cryptographic application and the PKI system. We also propose some advice about its cryptographic application system.

Key words: Internet of Vehicles, commercial cryptography, digital certificates
