Abstract: With the continuous development of intelligence and connectivity in heavy-duty commercial vehicles, vehicle remote control, wireless data transmission and other functions are becoming increasingly popular. However, this trend also brings about security concerns such as malicious manipulation and remote theft of vehicles. To reduce the potential information cybersecurity risks associated with remote control functions in heavy commercial vehicles, this study delves into the application of public key infrastructure (PKI) system. A set of processes for digital certificate issuance, control command issuance, and execution result uploading are formulated. Leveraging the security features of PKI system such as confidentiality and non-repudiation, it ensures the confidentiality, authenticity, and integrity of data communication between the vehicle's telematics device and the cloud service platform. This research provides valuable insights into enhancing the security of remote control functions in heavy-duty commercial vehicles.
