Vehicle-mounted virtual key implementation and communication method

Abstract

The invention provides a vehicle-mounted virtual key realization and communication method, which can improve the security. The method comprises the following steps of: firstly, a zero-knowledge identity authentication protocol based on a quasi-parallel vector error correction code is constructed between a vehicle-mounted terminal and a mobile phone terminal; a mutual authentication mechanism between the vehicle-mounted terminal and the mobile phone terminal is established; and then session key negotiation is carried out between the vehicle-mounted terminal and the mobile phone terminal, then the mobile phone terminal generates a signature and a public and private key pair, and finally, a storage battery voltage random characteristic description and true random number extraction method is adopted to establish a one-time password vehicle-mounted virtual key communication protocol based on ciphertext attributes. The novel vehicle-mounted virtual key communication protocol architecture isestablished on the basis of the novel vehicle-mounted virtual key communication protocol security of the cryptology principle, so that the problem of information security of the vehicle-mounted virtual key is solved, replay attack is prevented, and it is guaranteed that the identity authentication scheme has very high security.

Description

technical field [0001] The invention relates to the technical field of encryption and communication security, in particular to a vehicle-mounted virtual key realization and communication method. 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. Thereby overcoming the inconvenience of configuring multiple physical keys when a car is shared by multiple people, and avoiding the hidden danger of being unable to uniformly manage the car. [0003] Existing vehicle sharing technologies are generally based on mobile data communication networ...
