PKI is currently the implementation solution of OEMs to deal with the mainstream OTA information security.
Based on the capability of PKI system, it will be protected from three dimensions, such as vehicle cloud communication, upgrade package protection and in-car security communication.
Based on PKI system, it implements bidirectional authentication of vehicle-cloud communication, verification and encryption of upgrade packet signature, and verification of upgrade packet transmission between ECU in the car.
