Intelligent network connection automobile information safety platform based on end-pipe-cloud

The invention discloses an intelligent networked automobile information security platform based on end-pipe-cloud, and the platform carries out the security protection for a vehicle end, a cloud platform, and an Internet, and a trusted execution environment and a security level for the domain isolation, the deep defense, and the software and hardware integration are built at the vehicle end. Nodeverification, file layer encryption protection and key management service are established at the cloud end, and SSL/TLS secure communication is used between the nodes and between the nodes and the application program. For a communication network, a PKI-based communication encryption mechanism, a real-time network abnormal flow monitoring mechanism, an end-pipe-cloud integrated intrusion detectionmechanism, a national vulnerability perception and early warning mechanism and a multi-stage collaborative emergency response and online upgrading mechanism are established. And a data life cycle management mechanism, a key se
