Embodiment 1

[0116] The car keyless entry system provided by this embodiment can be found in figure 1 As shown, it includes at least a user terminal 1, a vehicle-mounted device 2, and a system management server 3 as a system platform.

[0117] The user terminal 1 in this embodiment may be various smart terminals, such as various smart phones, IPADs, readers, and the like. The user terminal 1 in this embodiment can directly interact with the vehicle-mounted device 2 to complete the control of the keyless entry of the car, or can interact with the vehicle-mounted device 2 through the system management server 3 to complete the control of the keyless entry of the car.

[0118] The user terminal 1 in this embodiment is provided with a smart card, and the smart card has a security chip SE (SecurityElement). The smart card SE in this embodiment can be various types of smart cards with security chips, such as a smart subscriber identification card (Subscriber Identification Module, subscriber ide...

Embodiment 2

[0195] In order to facilitate the understanding of the solutions of the present invention, this embodiment is described in conjunction with an example structure of a user terminal, a vehicle-mounted device, and a system management server.

[0196] see Figure 13 As shown, the user terminal in this embodiment includes a smart card 131, and the smart card includes a security chip for storing a user identity key corresponding to user identification information and performing encryption and decryption processing.

[0197] The smart card 131 is used to send a door lock control request including user identification information to the opposite end, and receive the first authentication information generated by the opposite end using the user identity key corresponding to the user identification information, and use the corresponding user identification information in the security chip. The user identity key processes the first authentication information to generate second authenticati...

Abstract

The invention provides an automobile key-free control certification method, a user terminal, a vehicle-mounted device and a server. The user terminal sends a vehicle door lock control request including user identification information to the opposite side, first certification information generated by using user identity secret key corresponding to the user identification information by the oppositeside is received, the first certification information is processed by using the user identity secret key, corresponding to the user identification information, stored in a safety chip of an intelligent card to generate second certification information, and the second certification information is sent to the opposite side for identity certification, so that the opposite side controls a vehicle door correspondingly according to an identity certification result of the second certification information. The user terminal replaces an intelligent key specially used for the vehicle, the user identitysecurity key is stored in the safety chip of the intelligent card of the user terminal and is not transmitted between the user terminal and the opposite side in the certification process, and thus, the identity security key is avoided from being intercepted, and the safety and user experience are improved.

Description

technical field [0001] The present invention relates to the field of automotive electronics, in particular to an automotive keyless control authentication method, a user terminal, a vehicle-mounted device and a server. Background technique [0002] Existing car keyless entry systems often use smart keys based on the combination of low-frequency induction and radio frequency communication technology. Users do not need to use mechanical keys when opening the car door, and do not need to take out the standard smart key when buying a car. When the smart key is close to the effective low-frequency detection distance of the vehicle-mounted device, the vehicle-mounted device senses the smart key, and the vehicle-mounted device will automatically identify and match the ID of the smart key through radio frequency. After successful pairing, the car door will open. The user does not even need to use the key, just press The engine can be ignited by pressing a button in the car or turnin...
