step S1, T-BOX (in the figure, the T-BOX is expressed by a vehicle-mounted terminal, and a person skilled in the art can understand that the T-BOX and the vehicle-mounted terminal have the same technical meaning in the fields of vehicle networking, intelligent network connection, intelligent driving and the like) respectively obtains signals sent by a plurality of vehicle-mounted control devices, and preset key information is acquired according to the signals;

Further, the acquiring preset key information according to the signal includes:
the T-BOX counts the signals sent by the vehicle-mounted control device after receiving the signals;
and when the signal exceeds the preset frame number, acquiring key information corresponding to the signal.
Further, the T-BOX acquires a signal sent by the vehicle-mounted control device through the gateway.
Further, after the T-BOX sends the authentication code to the TSP platform, if the authentication response of the TSP platform is obtained within the preset time, the authentication is determined to be successful.
Further, the encryption algorithm includes an AES algorithm.
Further, the encryption algorithm is an AES128 algorithm.
Further, the key information includes one or more of: the vehicle door state, the vehicle lock state, the vehicle window state, the power supply state, the average fuel consumption, the residual fuel quantity, the engine rotating speed, the vehicle speed, the endurance mileage and the window closing information in rainy days.
Further, the pushing, by the TSP platform, the acquired key information to a user includes: and the TSP platform pushes the key information through an application program in the intelligent terminal of the user.
To facilitate an understanding of the foregoing embodiments, the following description is provided for reference:
RS rainfall sensor, DCM door and window controller, TMPS tire pressure, CSS child monitoring, EMS engine and other controllers in the vehicle send corresponding signals to the T-BOX through the gateway. Therefore, the T-BOX acquires key information such as the state of a vehicle door and a vehicle window, the state of tire pressure, the state of children left, the rotating speed of an engine, the state of closing the window in rainy days and the like.
And then, the T-BOX performs preprocessing encryption on the acquired key information. Specifically, firstly, the T-BOX adopts an AES128 algorithm to perform safe encryption aiming at reported key information, secondly, the encrypted data is packaged according to a specified protocol, then the data is transmitted to an Rvmapp module in an MPU, and Gnss positioning information in an Otasrv module is finally packaged and sent to a TSP platform.
Of course, it will be appreciated that the T-BOX requires post-processing encryption before transmitting data to the TSP platform. Specifically, firstly, the T-BOX needs to send a message to the TSP platform to enable the platform to verify the identity of the T-BOX, and if the T-BOX is networked normally, registration and report can be carried out on the TSP platform. And after the registration is successful, the T-BOX reports an authentication command, sends an authentication code (the authentication code can be acquired through a registration response) to the TSP platform, and if the authentication response is acquired within 10 seconds, the authentication is considered to be successful, and the data packet can be transmitted.
And when the TSP platform is successfully registered and authenticated, acquiring the encrypted data packet transmitted from the T-BOX. And analyzing the encrypted data packet so as to acquire key information of the original vehicle. For example, the same AES128 algorithm is used to perform decryption processing, so as to obtain data of a door window state, a tire pressure state, a child left state, an engine speed, a window closing state in rainy days, and the like of the current vehicle, and then the TSP platform may push the decrypted information to the user (for example, the APP on the mobile phone pushes related vehicle data).
Here, with the aforementioned encryption reporting process of window closing information in rainy days as an example, the concept of pre-processing and post-processing encryption reporting proposed by the present invention is specifically described as follows:
the encrypted data reporting is divided into preprocessing encryption and postprocessing encryption, wherein the preprocessing encryption mainly relates to an encryption module of a T-BOX and a decryption module of a TSP platform. When the value detected by the rainfall sensor is greater than the rainfall threshold, the rainfall sensor sends a window closing request signal to the T-BOX. And the T-BOX receives the window closing request signal, continuously acquires the signal and counts, and when the accumulation is more than 5 frames, the signal acquisition is considered to be effective, and the window state judgment is carried out. When all windows are completely closed within 40 seconds, the windows are considered to be successfully closed in rainy days, and the flag bit is set to be 1; if the window state still shows that the window is not closed after the time exceeds 40 seconds, the window is considered to be failed to be closed in rainy days, and the flag bit is set to be 0.
The MCU module in the T-BOX adopts an AES128 algorithm to perform security encryption processing on the information of the rainy day window closing state, and the TSP platform decrypts the rainy day window closing state by using the same AES128 algorithm, wherein the rainy day window closing data can be the first byte of the eight lower bytes. Specifically, the T-BOX information encryption process: and the MCU module in the T-BOX sends a security verification signal SecrityValid to the TSP platform, wherein the security verification data can be written by a diagnostic tool. And forming a plaintext by the diagnosis safety number and the window closing data in rainy days, calculating by an AES algorithm to obtain a 16-byte encrypted number, and sending the 16-byte encrypted number to the TSP.
After receiving the 16-byte encrypted number, the TSP platform decrypts by adopting the same AES algorithm, safely acquires window closing information in rainy days, and pushes a message to a user mobile phone APP after decryption is successful, for example, when the window closing is successful in rainy days, the message can be pushed to display: the respected car owners can automatically close windows and skylights for people to avoid the rain of the cars. "; if the window closing is unsuccessful, pushing: when the automatic window closing is failed in raining, the window is required to be closed in time, so that the phenomenon that a favorite vehicle is wetted is avoided, and the burglary is prevented. "
The encryption method may further include the following steps:
the encrypted plaintext may be filled in the following manner as table 1, where the upper eight bytes are diagnostic security numbers, the first byte of the lower eight bytes is window closing information in rainy days, and the remaining bytes are reserved for relevant important information (for data expansion), and default is filled in 00.
TABLE 1 AES128 encryption algorithm results
The diagnosis safety number is written by a diagnosis tool when being calibrated by T-BOX, and each vehicle type has different safety numbers. If the vehicle diagnosis safety number is 0 xAB BC CD DE 11223344 and 0 in the window closing information in rainy days represents window closing failure information, the window is not completely closed; 1 indicates the window closing success information, indicating that the window is completely closed. The key is set to be 12365478, the combined plaintext AB BC CD DE 112233440000000000000001 obtains an encryption number of 1449D 62257 CE 557A 63821E FC 7F 962509 according to an AES encryption algorithm. After receiving the encrypted number, the TSP platform decrypts the encrypted number by using the same AES algorithm to obtain AB BC CD 112233440000000000000001, and simultaneously obtains the first byte number 01 in the low octet to obtain the window closing state data in rainy days.
In summary, the main design concept of the present invention is that, based on the traditional post-encryption, for the key information of the vehicle, a pre-encryption mechanism is further adopted, that is, the vehicle-mounted terminal T-BOX processes the reported data according to an encryption algorithm, so that the reported data becomes an unreadable ciphertext, specifically, an encryption number can be formed by the security verification number written by the diagnostic tool and the vehicle data to be reported, and after the encryption number is encrypted according to a preset encryption algorithm, the post-processing encryption operation between the T-BOX and the TSP platform based on the authentication mechanism is performed, that is, the identity is verified through authentication, and after the identity verification is completed, the TSP platform decrypts the encrypted data reported by the T-BOX according to the same encryption algorithm, so as to obtain the original data of the reported vehicle and send the original data to the user. The invention adopts a double encryption mode of pre-processing and post-processing, greatly enhances the safety and confidentiality of vehicle information, prevents the leakage of important information, and ensures the property safety and the personal safety of vehicle users.
