Abstract

The invention discloses a communication method of a vehicle-mounted virtual key, which is a novel vehicle-mounted virtual key communication protocol architecture designed on the basis of a cryptologyprinciple, and the design method of the vehicle-mounted virtual key is explained from a multi-angle and comprehensive perspective in the aspect of security.

Description

Technical field: [0001] The invention belongs to the technical field of encryption and communication security, and in particular relates to a communication method for a vehicle-mounted virtual key. Background technique: [0002] With the rapid development of society, the dream of cars entering the family has become a reality. With the change of people's daily travel habits, traditional cars and new energy vehicles are becoming more and more intelligent. Many manufacturers have introduced vehicle sharing technology based on various methods. These technologies do not rely on traditional vehicle physical keys, but unlock, lock doors, whistle, start the engine, etc. in the form of software. This overcomes the inconvenience of configuring multiple physical keys when multiple people share a car, and avoids the hidden danger of being unable to manage the car in a unified manner. Existing vehicle sharing technologies are generally based on mobile data communication networks of co...
