Method for securely connecting vehicle and Bluetooth key, and Bluetooth module and Bluetooth key

A method for securely connecting a vehicle and a Bluetooth key, wherein comprises:

• obtaining, by the Bluetooth key, the security information of the mobile terminal, and determining the authentication manner of the security authentication according to the security information;
• when a mobile terminal installed with a Bluetooth key and a vehicle Bluetooth module successfully establish a Bluetooth connection wherein the authentication manner is simple authentication or common authentication;
• generating, by the Bluetooth key, an authentication request according to the determined authentication manner, and sending the authentication request to the vehicle Bluetooth module;
• receiving, by the Bluetooth key, the authentication result returned by the vehicle Bluetooth module when the authentication manner of the authentication request is simple authentication;
• the authentication request is configured for the vehicle Bluetooth module to perform security authentication on the Bluetooth key according to the simple method;
• securely connecting, by the Bluetooth key, with the vehicle Bluetooth module when the authentication result is authentication passed;
• performing, by the Bluetooth key, security authentication with the vehicle Bluetooth module according to the common authentication manner when the authentication result indicates that authentication fails, or the authentication manner of the authentication request is common authentication;
• wherein the security information includes device change information of the mobile terminal, user change information, digital key change information and time information when the user logs in the Bluetooth key;
• determining, by the Bluetooth key, that the authentication manner of the security authentication is the simple authentication when the device change information of the mobile terminal, user change information, digital key change information and the time information when the user logs in the Bluetooth key meet the preset security conditions;
• determining, by the Bluetooth key, that the authentication manner of security authentication is the ordinary authentication when the device change information of the mobile terminal, user change information, digital key change information and the time information when the user logs in the Bluetooth key do not meet the preset security conditions.

A non-transient computer-readable storage medium having stored therein instructions that, when executed by a processor of a device, causes the device to perform a method for generating driving suggestions, the method comprises:

• receiving, by the vehicle Bluetooth module, an authentication request from the Bluetooth key, wherein the authentication manner of the authentication request is a simple authentication or an common authentication when a vehicle Bluetooth module successfully establishes a Bluetooth communication connection with a mobile terminal installed with a Bluetooth key;
• performing, by the vehicle Bluetooth module, security authentication on the Bluetooth key according to the simple authentication manner, and sending the authentication result to the Bluetooth key when the authentication manner of the authentication request is the simple authentication;
• securely connecting, by the vehicle Bluetooth module, with the Bluetooth key when the authentication result is authentication passed;
• performing, by the vehicle Bluetooth module, security authentication with the Bluetooth key according to the common authentication manner when the authentication result indicates that authentication fails, or the authentication manner of the authentication request is common authentication;
• wherein the vehicle Bluetooth module performs security authentication on the Bluetooth key according to the simple authentication manner, comprises:
• determining, by the vehicle Bluetooth module, whether there is a key whitelist;
• obtaining, by the vehicle Bluetooth module, the device information of the currently connected mobile terminal if there is a key whitelist, and determining whether there is a digital key matching the device information in the key whitelist;
• verifying, by the vehicle Bluetooth module, the digital key according to a preset verification rule if there is a digital key matching the device information in the key whitelist, and determining whether the security authentication is passed according to the verification result;
• wherein the vehicle Bluetooth module performs security authentication with the Bluetooth key according to the common authentication manner, further comprises:
• generating, by the vehicle Bluetooth module, a key whitelist, and storing the digital key in the key whitelist when the vehicle Bluetooth module and the Bluetooth key are successfully authenticated according to the common authentication manner, and if there is no key whitelist;
• or, storing, by the vehicle Bluetooth module, the digital key in the key whitelist if there is a key whitelist and there is no digital key matching the device information in the key whitelist;
• or, replacing, by the vehicle Bluetooth module, the digital key matching the device information in the key whitelist with the generated digital key if there is a key whitelist and there is a digital key matching the device information in the key whitelist.
