Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
As known from the background art, when a vehicle-mounted terminal logs in a network platform, the vehicle-mounted terminal directly sends a Vehicle Identification Number (VIN) or a device number of the vehicle-mounted terminal as a unique identification code to a server of the network platform, and the server authenticates the vehicle-mounted terminal according to the unique identification code. However, the method is easy to intercept the unique identification code by an external invader, and the security is poor.
Therefore, the embodiment of the invention provides an equipment authentication method, a vehicle-mounted terminal, a server and a system. And the vehicle-mounted terminal sends a login instruction at least carrying registration time and the encrypted number to the server, so that the server reversely converts the encrypted number into an equipment number according to the registration time and verifies the equipment number. After the vehicle-mounted terminal receives the authentication code sent by the server, the vehicle-mounted terminal logs in the server through the authentication code, and the equipment number is encrypted, so that the cracking difficulty of the equipment number is increased, and the safety is improved.
The server according to the embodiment of the present invention is a server of a network platform, and after the vehicle-mounted terminal logs in the server of the network platform, the vehicle-mounted terminal and the network platform can perform data transmission.
Referring to fig. 1, a flowchart of a device authentication method provided in an embodiment of the present invention is shown, where the device authentication method includes:
step S101: the vehicle-mounted terminal acquires registration time for the vehicle-mounted terminal to complete registration in the server in advance.
Preferably, before executing step S101, the vehicle-mounted terminal sends a registration instruction to the server, the vehicle-mounted terminal completes registration in the server, and at this time, the vehicle-mounted terminal records a registration time for completing registration, and the registration time indicates a time for completing registration of the vehicle-mounted terminal in the server.
That is, the vehicle-mounted terminal completes registration in the server in advance, and at this time, the server stores the device number of the vehicle-mounted terminal in the database for subsequent authentication operation (or simultaneously stores the VIN of the vehicle-mounted terminal in the database).
In the process of implementing step S101 specifically, the vehicle-mounted terminal obtains registration time when the vehicle-mounted terminal completes registration in the server in advance, where the registration time is recorded after the vehicle-mounted terminal completes registration, and the registration time may be beijing time (or may be selected according to actual needs).
Step S102: and the vehicle-mounted terminal determines a target conversion mode corresponding to the registration time from all preset conversion modes.
It should be noted that, a plurality of conversion manners are constructed in advance, and the various conversion manners are sorted, that is, each constructed conversion manner has a sequence number corresponding to itself, and the conversion manner has the specific functions of: a character is converted into another character according to a conversion method (which may be equivalent to encrypting the converted character).
In some embodiments, the specific contents of the plurality of conversion modes are as shown in table 1.
Table 1:
| serial number | Character(s) | Converting characters |
| 1 | A | 1 |
| 2 | B | 3 |
| 3 | C | 5 |
| 4 | D | 7 |
| 5 | E | 9 |
| …… | …… | …… |
Note that, the sequence numbers in table 1 are sequence numbers corresponding to various conversion methods, and "A, B, C, D and E" and "1, 3, 5, 7, and 9" in table 1 do not refer to specific contents, and are used to indicate that "convert a to 1" is one of the conversion methods.
In the process of specifically implementing step S102, the vehicle-mounted terminal obtains the last N digits of the second number corresponding to the registration time, where N is a positive integer less than 3, that is, N is 1 or 2, and determines, from all preset conversion modes, the conversion mode in which the serial number corresponds to the last N digits as the target conversion mode.
For example: assuming that N is 1 and the registration time of the in-vehicle terminal is 20 minutes, 53 seconds at 10 o' clock, 2021 year, 10 month, the last 1 digit of the second number corresponding to the registration time acquired by the in-vehicle terminal is "3", and the conversion mode with the serial number of "3" is determined as the target conversion mode.
Another example is: assuming that N is 2 and the registration time of the in-vehicle terminal is 10 o 10/13 s/5/10/2021, the last 2 digits of the second corresponding to the registration time acquired by the in-vehicle terminal are "13", and the conversion mode with the serial number of "13" is determined as the target conversion mode.
It will be appreciated that since the last 1 digit of the second number of registration time is 0 to 9, the sequence numbers of all transition modes are ordered from 0.
It should be noted that, when a conversion manner is constructed, multiple groups of conversion manners may be constructed, each group of conversion manners includes multiple conversion manners that are well ordered, and when the vehicle-mounted terminal determines a target conversion manner according to the registration time, the vehicle-mounted terminal may determine the target conversion manner from any one group of conversion manners by using the registration time.
Step S103: and the vehicle-mounted terminal converts the equipment number of the vehicle-mounted terminal into an encrypted number according to the target conversion mode.
In the process of implementing step S103 specifically, the in-vehicle terminal converts its own device number into an encrypted number by using the determined target conversion method.
Step S104: the vehicle-mounted terminal sends a login instruction at least containing registration time and an encryption number to the server.
In the process of implementing step S104 specifically, when the vehicle-mounted terminal logs in the server, the vehicle-mounted terminal needs to send a login instruction carrying a login protocol to the server, where the login protocol at least carries a provider ID, an Equipment model, an Equipment number, an Equipment International Mobile Equipment Identity (IMEI) number, and a registration time of the vehicle-mounted terminal.
That is, the login instruction sent by the in-vehicle terminal to the server carries at least the device number and the registration time of the in-vehicle terminal.
It should be noted that, in the above-mentioned login protocol, fields corresponding to different byte intervals indicate different information carried by the fields, that is, the vendor ID, the device model, the device number, the device IMEI number, and the registration time correspond to different fields in the login protocol, respectively, and specific contents of the login protocol are as shown in table 2, it should be noted that table 2 is only used for example, and specific contents of the login protocol are not specifically limited herein.
Table 2:
step S105: and the server determines a target conversion mode from all preset conversion modes according to the registration time.
In the process of specifically implementing step S105, after the server receives a login instruction at least including registration time and an encryption number sent by the vehicle-mounted terminal, the server determines a target conversion mode from all preset conversion modes according to the registration time.
In a specific implementation, the server obtains the last N-bit number of the second corresponding to the registration time, determines the conversion mode corresponding to the sequence number and the last N-bit number as the target conversion mode from all the preset conversion modes, and details of the server determining the target conversion mode may refer to the contents in step S102, which is not described herein again.
It can be understood that the vehicle-mounted terminal determines the target conversion mode from all conversion modes by using the registration time, and the vehicle-mounted terminal sends the login instruction carrying at least the registration time and the encryption number to the server, so that the server can also determine the target conversion mode from all conversion modes by using the registration time.
Step S106: and the server reversely converts the encrypted number by using a target conversion mode to obtain a device number and verifies the device number.
As can be seen from the content in step S103, the in-vehicle terminal converts the device number of the in-vehicle terminal into the encrypted number by using the target conversion method, and in the process of specifically implementing step S106, after determining the target conversion method by using the registration time, the server performs inverse conversion on the encrypted number (carried by the login instruction) by using the target conversion method, and inversely converts the encrypted number into the device number of the in-vehicle terminal.
And after the server carries out inverse conversion on the encrypted serial number to obtain the equipment serial number of the vehicle-mounted terminal, the server verifies the equipment serial number.
As can be seen from the above-mentioned content in step S101, after the in-vehicle terminal completes registration in the server, the server stores the device number of the in-vehicle terminal in the database. Therefore, the specific way for the server to verify the equipment number is as follows: the server determines whether an equipment number (obtained by reversely converting the encrypted number) exists in a preset database, if so, the equipment number is determined to pass the verification, and if not, the equipment number is determined not to pass the verification.
Step S107: and if the equipment number passes the verification, the server generates an authentication code.
In the process of implementing step S107, if the server determines that the device number obtained by inverse conversion of the encrypted number passes verification, the server generates an authentication code.
Step S108: the server sends the authentication code to the vehicle-mounted terminal.
In the process of implementing step S108, after the server generates the authentication code, the server sends the authentication code to the in-vehicle terminal.
Step S109: the vehicle-mounted terminal logs in the server by using the authentication code.
In the process of implementing step S109, after receiving the authentication code sent by the server, the vehicle-mounted terminal stores the authentication code, and logs in the server by using the authentication code to perform data transmission with the network platform.
In the embodiment of the invention, the vehicle-mounted terminal determines the target conversion mode by using the registration time and converts the own equipment number into the encryption number according to the target conversion mode. And the vehicle-mounted terminal sends a login instruction at least carrying registration time and the encrypted number to the server, so that the server reversely converts the encrypted number into an equipment number according to the registration time and verifies the equipment number. After the vehicle-mounted terminal receives the authentication code sent by the server, the vehicle-mounted terminal logs in the server through the authentication code, and the equipment number is encrypted, so that the cracking difficulty of the equipment number is increased, and the safety is further improved.
