Detailed description of the preferred embodiments
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.
All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
Examples
The present application provides a vehicle information encryption method as shown in fig. 1.
The Beidou positioning system-based vehicle mounted device acquires real-time position information of the vehicle at the first time and uploads the real-time position information of the vehicle to a remote terminal by using a first channel at the first time. The remote terminal checks the real-time position information of the vehicle according to the preset route information, if the checking result is correct, the second channel is opened and the next step is executed, and if the checking result is wrong, the real-time position information of the vehicle is obtained again and the second channel is kept closed.
If the real-time position information of the vehicle is found to be wrong, the vehicle is indicated to be in a fault or a driver of the vehicle does not drive the vehicle according to requirements, and the designated information of the vehicle obtained in the subsequent steps does not have research and analysis values.
Specifically, in the process of checking the real-time position information of the vehicle, if the longitude information, the latitude information, the azimuth information and the speed information of the vehicle are all correct, the checking result is judged to be correct. If the check result is correct, an opening signal is sent to the second channel, and the second channel receives the opening signal and is opened for a specified time.
It is to be noted in particular that, in order to protect the security and confidentiality of the vehicle's specifying information from the point of view of the channel, the second channel for transmitting part of the specifying information of the vehicle is only opened during the transmission, and remains closed otherwise.
Accordingly, in the process of checking the real-time position information of the vehicle, if any one of the longitude information, the latitude information, the azimuth information and the speed information of the vehicle is wrong, the checking result is judged to be wrong. If the check result is wrong, no signal is sent to the second channel, and the second channel is kept closed.
After checking that the real-time position information of the vehicle is correct, the information acquisition equipment installed on the vehicle acquires and processes the designated information of the vehicle. The remote terminal acquires the designated information of the vehicle at a second time, splits the designated information of the vehicle into the first information and the second information, and uploads the second information by using the second channel at the second time.
In particular, in one embodiment, the first time is set to a specified point in time, the second time is set to a specified point in time, and the first time is set to be earlier than the second time. For example, the first second during the running of the vehicle is set as the first time, and the twelfth second is set as the second time; alternatively, the first time may be set at the one hundred second and the second time may be set at the one hundred ten second during the running of the vehicle, as long as the first time is earlier than the second time.
In another embodiment, the first time is set to a specified time interval, the second time is set to the specified time interval, and the end point of the first time is set to be earlier than the start point of the second time. For example, the first time is set at the first second to the tenth second, and the second time is set at the twelfth second to the fifteenth second during the travel of the vehicle; alternatively, the first hour of the vehicle driving process is set as the first time, the second hour is set as the second time, and the first time is earlier than the second time.
Specifically, the first information is set as type information of the specifying information of the vehicle, such as name information of "vehicle speed", "engine revolution number", and "coolant temperature" arranged in order, and the second information is set as data information of the specifying information of the vehicle, such as specific data values of the vehicle speed, engine revolution number, and coolant temperature arranged correspondingly.
And acquiring the real-time position information of the vehicle at the second time, combining the real-time position information of the vehicle and the first information into combined information, and uploading the combined information by using the first channel at the second time. It will be readily appreciated that combining the real-time location information of the vehicle with the first information according to a predetermined algorithm may form an encryption of the specific information of the vehicle.
Since the first channel is independent of the second channel and the information transmission on the first channel is also public and non-information-encrypted, the real-time location information of the vehicle can be public, but the first information separated from the designation information of the vehicle needs to be encrypted.
And finally, the remote terminal receives the combined information and the second information uploaded at the same time, splits the combined information into the real-time position information and the first information of the vehicle, and combines the first information and the second information into the recovered specified information of the vehicle. In the above steps, the first information and the second information are transmitted through mutually independent information channels, so that mutually independent information security is formed, and the information of the two channels cannot be intercepted and decoded simultaneously. The first information and the second information can be analyzed in the next step only if the data recovered by the correct sorting mode at the same time point, and the error of any time and position can cause the decoded error.

Also, 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.

Alternatively, they may be implemented in program code executable by a computing device such that it is executed by the computing device when stored in a memory device, or separately as individual integrated circuit modules, or as a single integrated circuit module having multiple modules or steps.
The present invention is not limited to any specific combination of hardware and software.
