【Abstract】With the development of the "new four modernizations" of automobiles，automotive software is updated and iterated frequently.The traditionalofline upgrade function can no longer meet the needs of users and automakers.Therefore，itis necessary todevelop theover-the-air （OTA）upgrade function forautomobiles.Through OTA upgrades，car manufacturers can push new features to vehicles in real time and continuouslyoptimize the user product experience.However，the OTA upgrade processinvolves data interaction among multiple links such as the vehicle end， cloud，andcommunicationlinks，exposingthevehicletotheriskofcyberatacks.Thisarticlesystematicallyintroduces theinformation security response solutions in the development of OTA functions for commercial vehicles from four dimensions： upgrade package security，vehicle-cloud link security，vehicle-end secure storage，and security monitoring and emergency response，providing technical references forthe secure implementationof OTA incommercial vehicles.
