The embodiment of the invention provides an intelligent traffic message encryption transmission method, device, equipment and storage medium. The intelligent traffic message encryption transmission method in the embodiment of the invention is applied to an intelligent automobile, and one or more processors, a memory and one or more application programs are arranged in the intelligent automobile, wherein the one or more application programs are stored in the memory and are configured to be executed by the processors to realize the intelligent traffic message encryption transmission method.
As shown in fig. 1, fig. 1 is a schematic view of a scenario of an intelligent traffic message encryption transmission method according to an embodiment of the present invention, where the intelligent traffic message encryption transmission scenario includes an intelligent vehicle 10 and a background server 20, and an intelligent traffic message encryption transmission device is integrated in the intelligent vehicle 10, and a storage medium corresponding to the intelligent traffic message encryption transmission method is operated to execute steps of the intelligent traffic message encryption transmission method.
Fig. 2 is a flowchart of an intelligent traffic message encryption transmission method according to an embodiment of the present invention. As shown in fig. 2, the method includes the following steps S110 to S130.
S110, responding to a vehicle data uploading instruction, and acquiring current system time, current vehicle acquisition data and current vehicle positioning information.
In this embodiment, the technical scheme is described by using the intelligent automobile as an execution subject. In order to acquire some key vehicle data (such as driving speed, residual electric energy, driving mileage, working parameters of automobile equipment and the like) of the intelligent automobile, the key vehicle data are not sent to the background server in a clear text mode, when the intelligent automobile has a requirement for uploading data at a certain moment, the current system time, the current vehicle acquisition data and the current vehicle positioning information are acquired firstly at the local of the intelligent automobile, and the data can be uploaded to the background server after encryption processing.
The method comprises the following steps of:
1) The first is a timing generation mode, that is, after each preset command generation period, a vehicle data uploading command is automatically generated, for example, the generation time of the last vehicle data uploading command is T1, and the preset command generation period is T, and the generation time of the next vehicle data uploading command is t1+t;
2) The second is a fixed driving distance generation mode, that is, a preset driving distance is set at each interval to automatically generate a vehicle data uploading instruction, for example, a historical accumulated driving distance corresponding to a last vehicle data uploading instruction is D1, and the preset driving distance is D, and a historical accumulated driving distance corresponding to a next vehicle data uploading instruction is d1+d;
3) Thirdly, automatically generating a vehicle data uploading instruction every time the intelligent automobile senses a road side unit arranged on one side of a road;
4) The fourth is that an application program corresponding to the intelligent automobile is installed on an intelligent terminal (such as a smart phone) in communication connection with the intelligent automobile, and part of intelligent interactive control on the intelligent automobile can be realized on the application program, for example, a virtual button for triggering a vehicle data uploading instruction is arranged on an interactive interface of the application program, and when a user operates the intelligent terminal to click the virtual button for triggering the vehicle data uploading instruction, the virtual button for triggering the vehicle data uploading instruction can also be triggered to generate the vehicle data uploading instruction
Of course, in the specific implementation, the vehicle data upload instruction is not limited to the four generation methods described above, and may be generated in other ways, as long as the vehicle data upload instruction is triggered and generated. At the corresponding moment of generating the vehicle data uploading instruction, the current vehicle acquisition data (such as driving speed, residual electric energy, driving mileage, vehicle equipment working parameters and the like), the current system time and the current vehicle positioning information of the intelligent vehicle are acquired and acquired at the same time, and the current system time, the current vehicle acquisition data and the current vehicle positioning information acquired on the intelligent vehicle are in a current or clear state and cannot be directly uploaded to a background server.
And S120, if the current vehicle positioning information is determined to meet the first preset condition, encrypting the current vehicle positioning information based on a first preset encryption algorithm to obtain first encrypted data.
The first preset condition comprises a plurality of allowed passing areas.
In this embodiment, the encryption mode adopted is different from the existing vehicle data that is encrypted once and then uploaded to the background server, in that when it is determined that the current vehicle positioning information meets the first preset condition, the current vehicle positioning information is encrypted by adopting a first preset encryption algorithm, so as to obtain first encrypted data. And whether the current vehicle positioning information meets the first preset condition is judged, and whether the intelligent automobile is currently driven to a sensitive area in which the positioning data cannot be uploaded is also determined. If the current vehicle positioning information is determined to meet the first preset condition, the positioning position corresponding to the current vehicle positioning information is indicated to belong to one of a plurality of allowed passing areas included in the first preset condition, and at this time, the current vehicle positioning information can be encrypted based on a first preset encryption algorithm to obtain first encrypted data. The first encrypted data functions not only as encrypted data of the current vehicle positioning information but also as an encryption key for encrypting the current vehicle collected data later.
In one embodiment, as shown in fig. 3, step S120 includes:
s121, acquiring an asymmetric encryption model corresponding to the first preset encryption algorithm;
s122, acquiring current longitude and latitude information corresponding to the current vehicle positioning information;
s123, encrypting the current longitude and latitude information based on the asymmetric encryption model to obtain the first encrypted data.
In this embodiment, in order to encrypt the current vehicle positioning information, an asymmetric encryption model such as an RSA encryption algorithm corresponding to the first preset encryption algorithm may be obtained first, then current latitude and longitude information corresponding to the current vehicle positioning information is obtained (that is, the current latitude and longitude information in the current vehicle positioning information is obtained by analyzing the current latitude and longitude information instead of directly using the original current vehicle positioning information as data to be encrypted later), and finally the current latitude and longitude information is encrypted according to the asymmetric encryption model to obtain the first encrypted data.
The first encrypted data is encrypted for the first time, so that the first encrypted data is obtained to be safer, and then the first encrypted data is used as an encryption key to be more difficult to crack. After the intelligent automobile runs to one position, the intelligent automobile can correspond to different positioning positions, namely different vehicle positioning information, so that the first encryption data generated each time is continuously changed, and the cracking difficulty is higher.
For example, the intelligent automobile travels to the place a, and the place a corresponds to the latitude and longitude information A1, and the latitude and longitude information A1 is encrypted by an asymmetric encryption model to obtain encrypted data A2. The intelligent automobile runs to a place B (the place B is different from the place A, and the place A and the place B both belong to one of a plurality of allowed passing areas), the intelligent automobile corresponds to longitude and latitude information B1, and the longitude and latitude information B1 is encrypted by an asymmetric encryption model to obtain encrypted data B2. The encrypted data B2 and the encrypted data A2 are different encrypted data, the encrypted data A2 and the encrypted data B2 encrypt corresponding data to be encrypted respectively, and the two obtained encrypted results are different. And then the two encryption results are decrypted, the same decryption key is not used any more, but different decryption keys are used. Therefore, even if the encryption result is intercepted and obtained, the decryption difficulty is extremely high because the corresponding decryption key is difficult to obtain, and the data security is effectively ensured.
S130, taking the first encrypted data as an encryption key, encrypting the current vehicle collected data based on a second preset encryption algorithm to obtain second encrypted data, and sending the current system time, the first encrypted data and the second encrypted data to a background server.
In this embodiment, since the current vehicle positioning information is encrypted to obtain the first encrypted data, in order to improve the data security level of the current vehicle collected data, the first encrypted data may be used as an encryption key of a second preset encryption algorithm to encrypt the current vehicle collected data to obtain the second encrypted data. At this time, the current vehicle collected data and the current vehicle positioning information are no longer in a plaintext form, and at this time, the current system time, the first encrypted data and the second encrypted data are sent to a background server, so that the first encrypted data and the second encrypted data corresponding to the current system time of the intelligent automobile are stored in the background server. Therefore, the second encrypted data stored in the mode is a double encrypted result, and the first encrypted data is encrypted data subjected to primary encryption, so that the data security of the intelligent automobile is greatly improved.
In an embodiment, as shown in fig. 4, as a first specific embodiment in step S130, step S130 includes:
s131a, a symmetrical encryption model and an antagonistic neural network corresponding to the second preset encryption algorithm are obtained;
S132a, using the first encryption data as an encryption key and encrypting the current vehicle acquisition data through the symmetrical encryption model to obtain a current acquisition data encryption result;
s133a, performing operation by taking the first encrypted data as the input of the antagonistic neural network to obtain a first network output result;
and S134a, connecting the encryption result of the current acquired data with the output result of the first network to form the second encrypted data.
In this embodiment, after the first encrypted data is obtained locally in the smart car, when the first encrypted data is encrypted for the second time, a symmetric encryption model (such as DES encryption algorithm) and an antagonistic neural network corresponding to the second preset encryption algorithm may be obtained first. And then, the first encryption data is used as an encryption key, the current vehicle collected data is encrypted through the symmetrical encryption model, so that a current collected data encryption result is obtained, and the obtained current collected data encryption result can be regarded as a secondary encryption result. However, in order to improve the cracking difficulty, some interference data can be spliced in the encryption result of the current acquired data. The first encrypted data is used as input of the anti-neural network to operate, so that a first network output result is obtained, the result can be regarded as interference data processed by the anti-neural network, and the interference data is spliced with the current acquired data encryption result, so that second encrypted data which is extremely high in safety coefficient and difficult to crack can be obtained.
Of course, in order to decrypt the first encrypted data, the background server also needs to store a decryption key corresponding to the asymmetric encryption model in the background server, and decrypt the first encrypted data based on the decryption key and the decryption model corresponding to the asymmetric encryption model, so as to restore the current longitude and latitude information in a plaintext form, and convert the current longitude and latitude information in a data format so as to restore the current longitude and latitude information to obtain the front vehicle positioning information.
In order for the background server to decrypt the second encrypted data, a challenge sample recovery algorithm (such as a recovery algorithm at a CLEVER distance) corresponding to the challenge neural network needs to be stored in the background server, and the process of recovering the first encrypted data from the second encrypted data is specifically as follows:
the first step is to acquire the first encrypted data and the second encrypted data corresponding to a certain stored system time from a background server;
encrypting the first encrypted data based on a symmetric encryption model in a background server to obtain current encrypted data, and comparing the current encrypted data with the second encrypted data to obtain a difference comparison result;
the third step is to input the difference comparison result to an countermeasure sample recovery algorithm to obtain sample recovery data;
And the fourth step is to compare whether the sample recovery data is the same as the current encrypted data or not, if so, the recovery is successful, and one of the difference comparison result or the current encrypted data is used as the first encrypted data recovered by the second encrypted data instead of the first encrypted data stored by the background server.
In one embodiment, as shown in fig. 5, as a second specific embodiment in step S130, step S130 includes:
s131b, acquiring an isomorphic encryption model corresponding to the second preset encryption algorithm;
and S132b, encrypting the current vehicle acquisition data based on the homomorphic encryption model and the encryption key to obtain the second encrypted data.
In the present embodiment, the difference from the first embodiment of step S130 is that the expandable availability of the second encrypted data is sufficiently taken into consideration. The method adopts the full homomorphic encryption model to encrypt the current vehicle collected data, and fully utilizes the encryption result in the form of ciphertext after full homomorphic encryption to still participate in various operations, so as to obtain the same result as the result directly participating in the operations in the form of plaintext. In the background server, an isohomomorphic encryption model corresponding to a second preset encryption algorithm is stored, and then the isomorphic encryption model corresponding to the second preset encryption algorithm is directly stored. Therefore, the second encrypted data with extremely high security coefficient and capable of participating in ciphertext calculation to safely expand the application can be obtained based on the encryption process.
For example, the background server also stores a data processing model for performing operation on the second encrypted data, and in this case, the second encrypted data is not required to be restored to plaintext to obtain the driving speed, the remaining electric energy, the driving mileage, the operating parameters of the vehicle equipment, and the like, but the second encrypted data is directly input into the data processing model to perform operation to obtain the processing result.
In one embodiment, after step S110, the method further includes:
and if the current vehicle positioning information meets the second preset condition, encrypting the current vehicle collected data based on a third preset encryption algorithm to obtain third encrypted data, and storing the third encrypted data into a local first private storage space.
The second preset condition comprises a plurality of traffic forbidden and communication areas.
In this embodiment, when the intelligent automobile determines that the current vehicle positioning information meets the second preset condition, it indicates that the user may drive the intelligent automobile to a certain traffic prohibition and communication area, and at this moment, a vehicle data uploading instruction is generated in the intelligent automobile and a data uploading requirement is triggered. In order to more quickly check whether the current vehicle collected data can be uploaded to the background server at this time, it is required to determine whether the positioning position corresponding to the current vehicle positioning information belongs to one of the traffic-forbidden and communication areas in the second preset condition. If the positioning position corresponding to the current vehicle positioning information belongs to one of the traffic-forbidden and communication areas in the second preset condition, the current vehicle acquisition data cannot be uploaded to the background server. At this time, the current vehicle collected data may be encrypted based on a third preset encryption algorithm (such as an asymmetric encryption algorithm) local to the intelligent vehicle, so as to obtain third encrypted data, and the third encrypted data is stored in a local first private storage space. This third encrypted data may be automatically purged from the first private storage space after a predetermined data retention time (e.g., 30 days) is stored in the first private storage space. Therefore, the current vehicle acquired data which can be obtained by the intelligent vehicle in the traffic forbidden and communication area through the mode can not be uploaded to a background server, but is stored locally in a private mode. Meanwhile, the first encrypted data of the same intelligent automobile and the same system time corresponding to the current vehicle collected data cannot be uploaded to the background server, and the first encrypted data is stored in the first private storage space and can be cleared periodically (the clearing process can refer to the clearing process of the third encrypted data in the first private storage space).
In an embodiment, step S130 further includes:
if the time interval between the latest system time and the current system time exceeds the preset encrypted data storage time, deleting the local current system time, the first encrypted data and the second encrypted data.
In this embodiment, in step S130, the smart car sends the current system time, the first encrypted data and the second encrypted data to the background server to upload to the background server for storage and subsequent data application, and at the same time, the smart car can store the current system time, the first encrypted data and the second encrypted data locally. In order to realize regular cleaning of data in the intelligent automobile, if it is determined that the time interval between the latest system time and the current system time exceeds the preset encrypted data storage time in the intelligent automobile, deleting the local current system time, the first encrypted data and the second encrypted data.
In one embodiment, step S110 further includes:
and acquiring intelligent automobile user identity information corresponding to the current vehicle acquisition data and the current vehicle positioning information, and establishing a binding relationship with the current system time, the current vehicle acquisition data and the current vehicle positioning information.
In this embodiment, after acquiring the current vehicle acquisition data and the current vehicle positioning information of a certain intelligent vehicle in step S110, in order to make the background server know which intelligent vehicle is the data uploaded by, it is necessary to acquire the user identity information of the intelligent vehicle (for example, the identity information of the logged-in user corresponding to the vehicle-to-vehicle system of the intelligent vehicle) first, and then establish a binding relationship between the user identity information of the intelligent vehicle and the current system time, the current vehicle acquisition data and the current vehicle positioning information. And then, the intelligent automobile user identity information and the first encrypted data and the second encrypted data which are obtained by the intelligent automobile corresponding to the current system time are also in a binding relation, and the background server can more quickly determine the intelligent automobile for uploading the first encrypted data and the second encrypted data.
Therefore, the embodiment of the method can encrypt the current vehicle positioning information acquired by the intelligent automobile for the first time and then encrypt the current vehicle acquisition data for the second time, so that the first encrypted data and the second encrypted data which are higher in data security and difficult to crack are obtained and uploaded to the background server.
Fig. 6 is a schematic block diagram of an intelligent traffic message encryption transmission device according to an embodiment of the present invention. As shown in fig. 6, the present invention also provides an intelligent traffic message encryption transmission device 100 corresponding to the above intelligent traffic message encryption transmission method. The intelligent transportation message encryption transmission apparatus 100 includes a unit for performing the above intelligent transportation message encryption transmission method, and is configured in a smart car. Referring to fig. 6, the smart traffic message encryption transmission apparatus 100 includes: a data acquisition unit 110, a first encryption unit 120, and a second encryption unit 130.
The data acquisition unit 110 is configured to acquire the current system time, the current vehicle acquisition data, and the current vehicle positioning information in response to the vehicle data uploading instruction.
In this embodiment, the technical scheme is described by using the intelligent automobile as an execution subject. In order to acquire some key vehicle data (such as driving speed, residual electric energy, driving mileage, working parameters of automobile equipment and the like) of the intelligent automobile, the key vehicle data are not sent to the background server in a clear text mode, when the intelligent automobile has a requirement for uploading data at a certain moment, the current system time, the current vehicle acquisition data and the current vehicle positioning information are acquired firstly at the local of the intelligent automobile, and the data can be uploaded to the background server after encryption processing.
At the corresponding moment of generating the vehicle data uploading instruction, the current vehicle acquisition data (such as driving speed, residual electric energy, driving mileage, vehicle equipment working parameters and the like), the current system time and the current vehicle positioning information of the intelligent vehicle are acquired and acquired at the same time, and the current system time, the current vehicle acquisition data and the current vehicle positioning information acquired on the intelligent vehicle are in a current or clear state and cannot be directly uploaded to a background server.
The first encryption unit 120 is configured to encrypt the current vehicle positioning information based on a first preset encryption algorithm to obtain first encrypted data if it is determined that the current vehicle positioning information meets a first preset condition.
The first preset condition comprises a plurality of allowed passing areas.
In this embodiment, the encryption mode adopted is different from the existing vehicle data that is encrypted once and then uploaded to the background server, in that when it is determined that the current vehicle positioning information meets the first preset condition, the current vehicle positioning information is encrypted by adopting a first preset encryption algorithm, so as to obtain first encrypted data. And whether the current vehicle positioning information meets the first preset condition is judged, and whether the intelligent automobile is currently driven to a sensitive area in which the positioning data cannot be uploaded is also determined. If the current vehicle positioning information is determined to meet the first preset condition, the positioning position corresponding to the current vehicle positioning information is indicated to belong to one of a plurality of allowed passing areas included in the first preset condition, and at this time, the current vehicle positioning information can be encrypted based on a first preset encryption algorithm to obtain first encrypted data. The first encrypted data functions not only as encrypted data of the current vehicle positioning information but also as an encryption key for encrypting the current vehicle collected data later.
In one embodiment, the first encryption unit 120 is specifically configured to:
acquiring an asymmetric encryption model corresponding to the first preset encryption algorithm;
acquiring current longitude and latitude information corresponding to the current vehicle positioning information;
and encrypting the current longitude and latitude information based on the asymmetric encryption model to obtain the first encrypted data.
In this embodiment, in order to encrypt the current vehicle positioning information, an asymmetric encryption model such as an RSA encryption algorithm corresponding to the first preset encryption algorithm may be obtained first, then current latitude and longitude information corresponding to the current vehicle positioning information is obtained (that is, the current latitude and longitude information in the current vehicle positioning information is obtained by analyzing the current latitude and longitude information instead of directly using the original current vehicle positioning information as data to be encrypted later), and finally the current latitude and longitude information is encrypted according to the asymmetric encryption model to obtain the first encrypted data.
The first encrypted data is encrypted for the first time, so that the first encrypted data is obtained to be safer, and then the first encrypted data is used as an encryption key to be more difficult to crack. After the intelligent automobile runs to one position, the intelligent automobile can correspond to different positioning positions, namely different vehicle positioning information, so that the first encryption data generated each time is continuously changed, and the cracking difficulty is higher.
For example, the intelligent automobile travels to the place a, and the place a corresponds to the latitude and longitude information A1, and the latitude and longitude information A1 is encrypted by an asymmetric encryption model to obtain encrypted data A2. The intelligent automobile runs to a place B (the place B is different from the place A, and the place A and the place B both belong to one of a plurality of allowed passing areas), the intelligent automobile corresponds to longitude and latitude information B1, and the longitude and latitude information B1 is encrypted by an asymmetric encryption model to obtain encrypted data B2. The encrypted data B2 and the encrypted data A2 are different encrypted data, the encrypted data A2 and the encrypted data B2 encrypt corresponding data to be encrypted respectively, and the two obtained encrypted results are different. And then the two encryption results are decrypted, the same decryption key is not used any more, but different decryption keys are used. Therefore, even if the encryption result is intercepted and obtained, the decryption difficulty is extremely high because the corresponding decryption key is difficult to obtain, and the data security is effectively ensured.
The second encryption unit 130 is configured to encrypt the current vehicle collected data based on a second preset encryption algorithm with the first encrypted data as an encryption key, obtain second encrypted data, and send the current system time, the first encrypted data, and the second encrypted data to a background server.
In this embodiment, since the current vehicle positioning information is encrypted to obtain the first encrypted data, in order to improve the data security level of the current vehicle collected data, the first encrypted data may be used as an encryption key of a second preset encryption algorithm to encrypt the current vehicle collected data to obtain the second encrypted data. At this time, the current vehicle collected data and the current vehicle positioning information are no longer in a plaintext form, and at this time, the current system time, the first encrypted data and the second encrypted data are sent to a background server, so that the first encrypted data and the second encrypted data corresponding to the current system time of the intelligent automobile are stored in the background server. Therefore, the second encrypted data stored in the mode is a double encrypted result, and the first encrypted data is encrypted data subjected to primary encryption, so that the data security of the intelligent automobile is greatly improved.
In an embodiment, as a first specific embodiment of the second encryption unit 130, the second encryption unit 130 is specifically configured to:
obtaining a symmetrical encryption model and an antagonistic neural network corresponding to the second preset encryption algorithm;
Encrypting the current vehicle collected data by taking the first encrypted data as an encryption key and using the symmetric encryption model to obtain a current collected data encryption result;
calculating by taking the first encrypted data as the input of the antagonistic neural network to obtain a first network output result;
and connecting the current acquired data encryption result with the first network output result to form the second encrypted data.
In this embodiment, after the first encrypted data is obtained locally in the smart car, when the first encrypted data is encrypted for the second time, a symmetric encryption model (such as DES encryption algorithm) and an antagonistic neural network corresponding to the second preset encryption algorithm may be obtained first. And then, the first encryption data is used as an encryption key, the current vehicle collected data is encrypted through the symmetrical encryption model, so that a current collected data encryption result is obtained, and the obtained current collected data encryption result can be regarded as a secondary encryption result. However, in order to improve the cracking difficulty, some interference data can be spliced in the encryption result of the current acquired data. The first encrypted data is used as input of the anti-neural network to operate, so that a first network output result is obtained, the result can be regarded as interference data processed by the anti-neural network, and the interference data is spliced with the current acquired data encryption result, so that second encrypted data which is extremely high in safety coefficient and difficult to crack can be obtained.
Of course, in order to decrypt the first encrypted data, the background server also needs to store a decryption key corresponding to the asymmetric encryption model in the background server, and decrypt the first encrypted data based on the decryption key and the decryption model corresponding to the asymmetric encryption model, so as to restore the current longitude and latitude information in a plaintext form, and convert the current longitude and latitude information in a data format so as to restore the current longitude and latitude information to obtain the front vehicle positioning information.
In order for the background server to decrypt the second encrypted data, a challenge sample recovery algorithm (such as a recovery algorithm at a CLEVER distance) corresponding to the challenge neural network needs to be stored in the background server, and the process of recovering the first encrypted data from the second encrypted data is specifically as follows:
the first step is to acquire the first encrypted data and the second encrypted data corresponding to a certain stored system time from a background server;
encrypting the first encrypted data based on a symmetric encryption model in a background server to obtain current encrypted data, and comparing the current encrypted data with the second encrypted data to obtain a difference comparison result;
the third step is to input the difference comparison result to an countermeasure sample recovery algorithm to obtain sample recovery data;
And the fourth step is to compare whether the sample recovery data is the same as the current encrypted data or not, if so, the recovery is successful, and one of the difference comparison result or the current encrypted data is used as the first encrypted data recovered by the second encrypted data instead of the first encrypted data stored by the background server.
In an embodiment, as a second specific embodiment of the second encryption unit 130, the second encryption unit 130 is specifically configured to:
acquiring an isomorphic encryption model corresponding to the second preset encryption algorithm;
and encrypting the current vehicle collected data based on the homomorphic encryption model and the encryption key to obtain the second encrypted data.
In the present embodiment, the difference from the first specific embodiment of the second encryption unit 130 is that the expandable availability of the second encrypted data is sufficiently taken into consideration. The method adopts the full homomorphic encryption model to encrypt the current vehicle collected data, and fully utilizes the encryption result in the form of ciphertext after full homomorphic encryption to still participate in various operations, so as to obtain the same result as the result directly participating in the operations in the form of plaintext. In the background server, an isohomomorphic encryption model corresponding to a second preset encryption algorithm is stored, and then the isomorphic encryption model corresponding to the second preset encryption algorithm is directly stored. Therefore, the second encrypted data with extremely high security coefficient and capable of participating in ciphertext calculation to safely expand the application can be obtained based on the encryption process.
For example, the background server also stores a data processing model for performing operation on the second encrypted data, and in this case, the second encrypted data is not required to be restored to plaintext to obtain the driving speed, the remaining electric energy, the driving mileage, the operating parameters of the vehicle equipment, and the like, but the second encrypted data is directly input into the data processing model to perform operation to obtain the processing result.
In one embodiment, the smart traffic message encryption transmission apparatus 100 further comprises:
and the third encryption unit is used for encrypting the current vehicle collected data based on a third preset encryption algorithm to obtain third encrypted data if the current vehicle positioning information meets the second preset condition, and storing the third encrypted data into a local first private storage space.
The second preset condition comprises a plurality of traffic forbidden and communication areas.
In this embodiment, when the intelligent automobile determines that the current vehicle positioning information meets the second preset condition, it indicates that the user may drive the intelligent automobile to a certain traffic prohibition and communication area, and at this moment, a vehicle data uploading instruction is generated in the intelligent automobile and a data uploading requirement is triggered. In order to more quickly check whether the current vehicle collected data can be uploaded to the background server at this time, it is required to determine whether the positioning position corresponding to the current vehicle positioning information belongs to one of the traffic-forbidden and communication areas in the second preset condition. If the positioning position corresponding to the current vehicle positioning information belongs to one of the traffic-forbidden and communication areas in the second preset condition, the current vehicle acquisition data cannot be uploaded to the background server. At this time, the current vehicle collected data may be encrypted based on a third preset encryption algorithm (such as an asymmetric encryption algorithm) local to the intelligent vehicle, so as to obtain third encrypted data, and the third encrypted data is stored in a local first private storage space. This third encrypted data may be automatically purged from the first private storage space after a predetermined data retention time (e.g., 30 days) is stored in the first private storage space. Therefore, the current vehicle acquired data which can be obtained by the intelligent vehicle in the traffic forbidden and communication area through the mode can not be uploaded to a background server, but is stored locally in a private mode. Meanwhile, the first encrypted data of the same intelligent automobile and the same system time corresponding to the current vehicle collected data cannot be uploaded to the background server, and the first encrypted data is stored in the first private storage space and can be cleared periodically (the clearing process can refer to the clearing process of the third encrypted data in the first private storage space).
In one embodiment, the smart transportation message encryption transmission apparatus 100 further includes:
and the data periodic clearing unit is used for deleting the local current system time, the first encrypted data and the second encrypted data if the time interval between the latest system time and the current system time exceeds the preset encrypted data storage time.
In this embodiment, the smart car in the second encryption unit 130 sends the current system time, the first encrypted data and the second encrypted data to the background server to upload to the background server for storage and subsequent data application, and meanwhile, the smart car can store the current system time, the first encrypted data and the second encrypted data locally. In order to realize regular cleaning of data in the intelligent automobile, if it is determined that the time interval between the latest system time and the current system time exceeds the preset encrypted data storage time in the intelligent automobile, deleting the local current system time, the first encrypted data and the second encrypted data.
In one embodiment, the smart transportation message encryption transmission apparatus 100 further includes:
And the data binding unit is used for acquiring intelligent automobile user identity information corresponding to the current vehicle acquisition data and the current vehicle positioning information, and establishing a binding relationship with the current system time, the current vehicle acquisition data and the current vehicle positioning information.
In this embodiment, after acquiring the current vehicle acquisition data and the current vehicle positioning information of a certain intelligent vehicle, in order to make the background server know which intelligent vehicle is the data uploaded by, it is necessary to acquire the user identity information of the intelligent vehicle (for example, the identity information of the login user corresponding to the vehicle machine system of the intelligent vehicle) first, and then establish a binding relationship between the user identity information of the intelligent vehicle and the current system time, the current vehicle acquisition data and the current vehicle positioning information. And then, the intelligent automobile user identity information and the first encrypted data and the second encrypted data which are obtained by the intelligent automobile corresponding to the current system time are also in a binding relation, and the background server can more quickly determine the intelligent automobile for uploading the first encrypted data and the second encrypted data.
Therefore, the embodiment of the device can encrypt the current vehicle positioning information acquired by the intelligent automobile once and then encrypt the current vehicle acquisition data for the second time, so that the first encrypted data and the second encrypted data which are higher in data security and difficult to crack are obtained and uploaded to the background server.
