This section will mainly introduce the electrical framework of the Intelligent Connected Vehicles（ICVs）in network security and data security，including the main functions of the on-board domain controller，security application scenarios of chip security firmware and domain controller. The vehicle domain controller is based on Electronic Control Unit（ECU）to realize the function integration of all functional controllers. By concentrating the function into the domain controller，it is a key step for the evolution and development of the vehicle to advanced Electrical/Electronic architecture（E/E architecture）. This section will specifically introduce the power and chassis controller，central computing unit，body controller，etc. The chip HSM security firmware realizes the safe start，safe refresh and safe communication，which effectively guarantees the safe and credible management of the whole life cycle of the vehicle ECU. The security application scenario of the domain controller is the HSM security firmware application scenario oriented to the EE architecture of the vehicle. This section will introduce the specific vehicle domain controller FOTA：focus on software upgrade the firmware and software dynamic safety problem，user，and the data security scenario：focus on automotive battery data and containment of the data of autopilot，remote fault diagnosis reliable access scenario-important to solve the problem of illegal diagnostic access.
