Application of SOME/IP protocol in automobile network security

The SOME/IP (Scalable Service-Oriented Middleware over IP) protocol is a communication protocol designed for automotive electronic systems, especially in autonomous driving and in-vehicle infotainment systems. This protocol is located in the application layer of the OSI model and is mainly responsible for efficiently implementing service communications between different electronic control units (ECUs). The core functions of the SOME/IP protocol include service discovery, request, and response operations.
