Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Referring to fig. 1, fig. 1 is a schematic flow chart of a transmission method of automatic driving data according to an embodiment of the present disclosure, where the transmission method of automatic driving data includes the following steps:
step S101, obtaining automatic driving data to be transmitted, wherein the automatic driving data comprises first subdata and second subdata, and the safety level of the first subdata is higher than that of the second subdata;
step S102, processing the first subdata based on a preset means to obtain target subdata, wherein the preset means comprises an encryption processing means;
step S103, transmitting target data to second electronic equipment, wherein the target data comprises the target subdata and the second subdata.
The automatic driving data may be various data received or transmitted during the driving process of the automatic driving vehicle, for example, the data may be transmitted to the remote control cabin by the automatic driving vehicle, or the data may be received from the remote control cabin by the automatic driving vehicle. Furthermore, the above-mentioned automatic driving data may also be data transmitted between different devices in the automatic driving vehicle, for example, control data for controlling an in-vehicle component, which is input by a user through an in-vehicle display screen, in which case the first electronic device and the second electronic device are two different devices in the automatic driving vehicle.
In addition, the automatic driving data may be data in the form of an Interface Description Language (IDL) file. The following takes the automatic driving data as an IDL file as an example, and further explains the automatic driving data transmission method provided by the disclosed embodiment.
Specifically, a Service-Oriented Architecture (SOA) framework may be preconfigured in the first electronic device. The transmission method of the automatic driving data may be a message sent by any SOA application program in the first electronic device based on the SOA framework. Specifically, referring to fig. 2, after the SOA application program a generates data to be transmitted, the IDL compiler in the SOA framework compiles the data to be transmitted to obtain an IDL file, and then the SOA framework processes the first sub-data in the IDL file by using the preset means to obtain target data. The SOA frame may transmit the target Data to the SOA frame of the second electronic device through a Data Distribution Service (DDS) centered on the Data, and the SOA frame of the second electronic device decrypts the target Data, so as to obtain the Data to be transmitted, thereby completing the Data transmission process.
Since the IDL file generally has a plurality of different methods and events therein, the first sub-data may be any method or event (event) in the IDL file. Correspondingly, the second sub-data may also be any method or event in the IDL file. And the first subdata and the second subdata are different data.
It can be understood that the automatic driving data may include at least one of the first sub-data and at least one of the second sub-data, and the processing of the first sub-data based on the preset means may refer to: processing all first subdata in the automatic driving data based on a preset means, and obtaining target subdata corresponding to the first subdata one by one. The data content of different first subdata in the automatic driving data can be different, and the data content of different second subdata in the automatic driving data can be different. After the target sub-data is obtained, the SOA framework may combine the target sub-data and the second sub-data to obtain the target data.
In an embodiment of the present disclosure, identification information may be set for the first sub-data in the IDL file, so that the SOA framework may determine the first sub-data in the IDL file by recognizing the identification information, and further process the determined first sub-data by using the preset means.
The Encryption processing means may be various types of Encryption methods in the related art, for example, an Encryption method such as asymmetric cryptography (RSA) or Advanced Encryption Standard (AES) Encryption may be used.
In this embodiment, before the transmission of the autonomous driving data, only a part of the first subdata with a higher security level in the autonomous driving data is encrypted, and the second subdata with a lower security level is not encrypted, so that the security of the autonomous driving data transmission can be ensured, and meanwhile, the occupation of a Central Processing Unit (CPU) resource of the autonomous driving vehicle in the encryption process can be reduced, thereby improving the data transmission effect.
Optionally, the automatic driving data includes at least two pieces of the first subdata, and each piece of the first subdata includes a safety level identifier;
the processing the first subdata based on a preset means to obtain target subdata comprises the following steps:
and for each first subdata, determining a preset means corresponding to the first subdata in a target configuration file based on the safety level identification, and processing the first subdata based on the preset means corresponding to the first subdata to obtain the target subdata corresponding to the first subdata, wherein the target configuration file comprises the corresponding relation between the safety level identification and the preset means, and the preset means corresponding to different safety level identifications are different.
In particular, the amount of cpu resources occupied by the process of encrypting data due to different encryption algorithms is typically different. And the more cpu resources are generally occupied by the encryption algorithm with better encryption effect. The types of data to be transmitted in the autonomous driving vehicle are various, and the safety requirements of different data to be transmitted are usually different.
Based on this, in the embodiment of the present disclosure, a corresponding security level identifier may be configured in each first sub-data (i.e., event or method) in the IDL file in advance, where the security level identifier is used to indicate a security level of the first sub-data to which the security level identifier belongs. It can be understood that related personnel may set the security level identifier in advance for various types of files, and thus, when the SOA framework acquires the IDL file, the SOA framework may first acquire the security level identifier of each event or method in the IDL file, and then process the event or method by using a corresponding preset means according to the security level identifier of each event or method.
It can be understood that, since the second sub-data is data that does not need to be encrypted, the security level identifier may not be configured in the second sub-data, and certainly, the security level identifier may also be configured in the second sub-data, and the security level identifier in the second sub-data is used to indicate that encryption processing is not needed.
In this embodiment, by configuring a corresponding security level identifier in each first subdata, when the SOA framework acquires the IDL file, the SOA framework may first acquire the security level identifier of each first subdata in the IDL file, and then process the event or the method by using a corresponding preset means according to the security level identifier of each first subdata. Because the corresponding preset means can be adopted for processing according to the security level of each first subdata, the processing effect of the IDL file is favorably improved.
Optionally, the encryption modes in the preset means corresponding to different security level identifiers are different.
It can be understood that different encryption methods have different encryption effects. In an embodiment of the present disclosure, the first sub-data with a higher security level may be encrypted with a better encryption effect, so as to improve data security. Correspondingly, the first subdata with lower security level is encrypted by adopting the encryption method with poorer encryption effect and less CPU resource occupied in the encryption process so as to save the CPU resource.
In the embodiment, different encryption is adopted for the first subdata with different security levels, so that the transmitted data can be effectively protected, and meanwhile, the CPU resource occupation in the encryption process can be further reduced.
Optionally, the preset means further comprises at least one of: compression processing and add checks.
Specifically, the compression processing may be processing based on various types of compression processing manners in the related art. The adding check is to add a check flow in the first sub-data, and after the adding check, when the second electronic device parses the first sub-data, the first sub-data can be obtained only after the corresponding check is completed, where the added check mode may be various types of check modes in the related art, for example, cyclic Redundancy Check (CRC) check and the like.
In an embodiment of the present disclosure, the different preset means corresponding to the different security level identifiers may specifically be: different encryption means, whether compression processing is performed, whether verification is added, and the like. For example, the preset means corresponding to the security level 1 is as follows: and the encryption mode A is adopted for encryption and compression processing without adding verification. The preset means corresponding to the security level 2 is as follows: and the encryption mode A is adopted for encryption, compression processing is not carried out, and verification is added.
It is understood that the preset means processing may include other data processing means in the related art besides the three listed data processing means.
In this embodiment, the preset means includes multiple processing manners such as encryption, compression processing, and addition of check, which is beneficial to processing the first sub-data with different security levels by using different preset means.
Optionally, the preset means corresponding to the first sub-data includes: target compression mode processing, target verification mode processing and target encryption mode processing.
In this embodiment, since the preset means corresponding to the first sub-data includes a target compression method process, a target verification method process, and a target encryption method process, when the first sub-data is processed, the first sub-data may be compressed, encrypted, and check-added respectively.
Optionally, the processing the first sub-data based on a preset means corresponding to the first sub-data to obtain the target sub-data includes:
calling a target plug-in a target plug-in library to process the first subdata based on a preset means corresponding to the first subdata to obtain the target subdata, wherein the target plug-in library comprises a plug-in used for processing the first subdata, and the target plug-in is a plug-in matched with the preset means corresponding to the first subdata in the target plug-in library.
In the embodiment, when the first sub-data is processed, the first sub-data is processed in a plug-in calling mode, so that related personnel do not need to pay attention to specific implementation of the algorithm in a specific service scene, only the plug-ins in the plug-in library need to be loaded according to the configuration file when the SOA framework is initialized, a user writing the SOA application program does not need to know the specific implementation of the algorithm, and only the safety level at which a method or an event in service needs to be processed needs to be explicitly pointed out when the IDL file is defined, so that the implementation process of the data transmission mode provided by the embodiment of the disclosure is facilitated to be simplified.
Optionally, the target plug-in includes a first sub plug-in, a second sub plug-in and a third sub plug-in, where the first sub plug-in is a plug-in the target plug-in library corresponding to the target compression mode, the second sub plug-in is a plug-in the target plug-in library corresponding to the target verification mode, and the second sub plug-in is a plug-in the target plug-in library corresponding to the target encryption mode;
the calling a target plug-in a target plug-in library based on the preset means corresponding to the first subdata to process the first subdata to obtain the target subdata, and the method comprises the following steps:
compressing the first subdata based on the first sub-plug-in, adding verification processing to the first subdata based on the second sub-plug-in, and encrypting the first subdata based on the third sub-plug-in to obtain the target subdata.
In one embodiment of the present disclosure, the target plug-in library may include a first sub plug-in library, a second sub plug-in library and a second sub plug-in library.
The first sub-plug-in library comprises at least two first plug-ins, the at least two first plug-ins correspond to at least two compression modes one by one, and the first sub-plug-ins are first plug-ins corresponding to the target compression mode in the at least two first plug-ins;
the second sub plug-in library comprises at least two second plug-ins, the at least two second plug-ins correspond to the at least two verification modes one by one, and the second sub plug-in is a second plug-in corresponding to the target verification mode in the at least two second plug-ins;
the third sub plug-in library comprises at least two third plug-ins, the at least two third plug-ins correspond to the at least two encryption modes one by one, and the third sub plug-in is a third plug-in corresponding to the target encryption mode in the at least two third plug-ins.
Specifically, the first sub-plug-in library, the second sub-plug-in library and the third sub-plug-in library may be constructed in advance. Specifically, the corresponding first plug-in can be constructed according to different compression algorithms, and then the constructed first plug-in is stored in the first sub plug-in library. Accordingly, a corresponding second plug-in may be constructed according to different verification algorithms, and then the constructed second plug-in is stored in the second sub plug-in library. A corresponding third plug-in may be constructed according to a different encryption algorithm and then stored in the third sub-plug-in library. Therefore, when the first subdata needs to be compressed, added with verification and encrypted, the SOA framework can directly call the corresponding target plug-in from the corresponding plug-in library for processing, and the compression, added verification, encryption and other processing processes are completed through the called target plug-in.
In this embodiment, since the plug-ins in the plug-in library can be configured in advance, relevant personnel do not need to pay attention to specific implementation of the algorithm in a specific service scene, and only need to load the plug-ins in the plug-in library according to the configuration file when the SOA framework is initialized, a user writing the SOA application program does not need to know the specific implementation of the algorithm, and only needs to explicitly specify what security level the method or event in service needs to be processed in defining the IDL file, thereby facilitating simplification of the implementation process of the data transmission method provided by the embodiment of the present disclosure.
