Embodiment 1

[0062] Such as figure 1 As shown, a kind of dynamic password-based vehicle remote verification method of the present invention is described in detail, including the following steps:

[0063] Step S101: The on-vehicle system pre-stores its own vehicle key and dynamic password generation algorithm, and the vehicle key is in one-to-one correspondence with the vehicle identification code of the vehicle;

[0064] Step S102: The server pre-stores the vehicle key, the correspondence between the vehicle key and the vehicle identification code, and a dynamic password generation algorithm.

[0065] The vehicle-mounted system implants the vehicle key, dynamic password generation algorithm, etc. into the system during the production stage, and also stores the same vehicle key, dynamic password algorithm, and the corresponding relationship between the vehicle key and the vehicle identification code on the server side.

[0066] Vehicle Identification Number (VIN), VIN is the abbreviation o...

Embodiment 2

[0083] Such as figure 2 As shown, a kind of dynamic password-based vehicle remote verification method of the present invention is described in detail, including the following steps:

[0084] Step S201: The vehicle-mounted system pre-stores its own vehicle key and dynamic password generation algorithm, and the vehicle key is in one-to-one correspondence with the vehicle's vehicle identification code;

[0085] Step S202: The server pre-stores the vehicle key, the correspondence between the vehicle key and the vehicle identification code, and a dynamic password generation algorithm.

[0086] Step S203: The vehicle-mounted system uses the pre-stored vehicle key and the dynamic password generation algorithm to calculate the first dynamic password according to the current random parameter (in this embodiment, the random parameter is the number of times the vehicle-mounted system sends vehicle data requests to the server);

[0087] When the random parameter is the number of request...

Embodiment 3

[0098] Such as image 3 As shown, a kind of vehicle remote authentication system based on dynamic password of the present invention comprises: vehicle-mounted system 1 and server 2,

[0099] The vehicle system 1 includes:

[0100] The first calculation module 11 is used to calculate the first dynamic password by using the pre-stored vehicle key and the dynamic password generation algorithm according to the current random parameters;

[0101] A data reporting module 12, configured to report the vehicle data to be transmitted, the vehicle identification code and the first dynamic password to the server;

[0102] The server 2 includes:

[0103] The password authentication module 21 is configured to verify the first dynamic password, and when the verification is passed, confirm that the received vehicle data is valid, otherwise, confirm that the received vehicle data is invalid.

[0104] Preferably, the vehicle-mounted system 1 also includes:

[0105] The first storage module ...

Abstract

The invention discloses a vehicle remote authentication method based on a dynamic password and a vehicle remote authentication system thereof. The method comprises the steps that step A: a vehicle-mounted system obtains a first dynamic password through calculation by adopting a pre-stored vehicle secret key and a dynamic password generation algorithm according to current random parameters; step B: the vehicle-mounted system reports vehicle data to be transmitted, a vehicle identification code and the first dynamic password to a server; and step C: the server verifies the first dynamic password, and the received vehicle data are determined to be effective if verification is passed, or the received vehicle data are determined to be ineffective. According to the vehicle remote authentication method based on the dynamic password and the vehicle remote authentication system thereof, the dynamic password generated each time is different due to difference of the random parameters in each time of authentication. Unpredictability of the password each time is guaranteed by the randomness of the parameters in each time of calculation so that the security of the system is guaranteed in the basic link of password authentication.
