The in-vehicle system and an external server for storing external tool information provide a vehicular communication system. The external tool information provides a tool public key and key identification information. The tool public key pairs with the tool secret key. When the external tool requests communication connection with the in-vehicle system, the tool key acquisition device transmits the key identification information to the external server, so that the tool key acquisition device acquires the tool public key from the external server. The communication controller performs cryptographic communication with the external tool using the tool public key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"In-vehicle system and communication method","description":"An in-vehicle system for communicating with an external tool for storing a tool secret key includes: a communication device; a tool key acquisition device; and a communication controller.
