Research on the Application of Engine Mechanism in Secure Communication of Internet of Vehicles

In Internet of Vehicles communication, encryption technology is commonly used to ensure the safety of data transmission. OpenSSL provides encryption libraries, but there are certain risks in practical applications. Therefore, using third-party encryption libraries or encryption machines is the best choice for commercial applications. The Engine mechanism is a way to use a third-party encryption library or encryption machine. This article analyzes the security mechanism of the Internet of Vehicles, introduces the principle and specific usage of the Engine mechanism in detail, and shows an application example in the national security encryption algorithm.
