Security information adaptive communication system for internet of vehicles

The invention relates to a security information adaptive communication system for internet of vehicles. The security information adaptive communication system is arranged in a communication sub-layer of each communication terminal and is characterized by comprising a message transmission frequency adaptive module, a message compression assembly module, a message priority module and message encryption/decryption module, wherein all the modules are used for solving the problems of failure of adaptive adjustment of communication service frequency, message transmission redundancy and priority service mechanism insufficiency in the internet of vehicles. In addition, the system further comprises a message encryption/decryption module for encrypting formed message to solve the problem of communication security. Therefore, the security information adaptive communication system can be widely used in the field of traffic control and communication of internet of things.
