[0031] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In actual applications, the standard AES algorithm (such as AES-128) includes 10 rounds of encryption, while AES-256 includes 14 rounds. This is a considerable burden for the vehicle terminal. In order to reduce the burden of data encryption when the vehicle terminal uploads data, the vehicle terminal in the embodiment of the present invention can use the Advanced Encryption Standard algorithm with 6 rounds of encryption to encrypt data. For details, please refer to Figure 1 , Figure 1 An intelligent connected vehicle management system according to an embodiment of the present invention is shown; Figure 1 As shown, the intelligent networked vehicle management system 10 may include: an on-board terminal 110, a data aggregation platform 120 and a supervision platform 130; wherein:

[0033] The vehicle terminal 110 is installed on the intelligent network-connected vehicle. The vehicle terminal 110 is used to collect the operation perception data of the intelligent network-connected vehicle, and encrypt the operation perception data using the advanced encryption standard algorithm of the 6-round encryption process, and then send it to the data aggregation platform 120;

[0034] The data aggregation platform 120 is used to receive the encrypted operation perception data and decrypt the encrypted operation perception data; the data aggregation platform 120 provides an application development interface to the outside world and provides data services through the application development interface;

[0035] The supervision platform 130 is used to obtain the operation perception data from the data aggregation platform 120 by accessing the application development interface.

[0036] In an embodiment of the present invention, the vehicle-mounted terminal 110 can be installed on an intelligent connected vehicle; an intelligent connected vehicle may refer to a vehicle that integrates advanced information and communication technologies, sensor technologies, artificial intelligence, big data analysis and other technologies to achieve efficient interconnection and intelligent interaction between vehicles and vehicles (V2V), vehicles and infrastructure (V2I), vehicles and networks (V2N), and vehicles and pedestrians (V2P).

[0037] In actual applications, the vehicle-mounted terminal 110 can collect operating data of the intelligent connected vehicle through the CAN (Controller Area Network) bus and the vehicle-mounted Ethernet, and obtain perception information from the vehicle-mounted sensors in the intelligent connected vehicle, thereby obtaining operating perception data based on the operating data and the perception data, and the operating perception data may include operating data and perception data.

[0038] The operating data may refer to data related to the vehicle operating status, including status information of the vehicle's mechanical, electrical and electronic systems. Such data is usually generated by an on-board control unit and transmitted to the on-board terminal 110 via a CAN bus or an on-board Ethernet.

[0039] Common operating data types may include: engine data (for example: engine speed, fuel consumption, engine temperature, ignition timing, emission data), transmission data (for example: current gear, transmission oil temperature, shift time), braking system data (for example: brake pressure, brake pedal position, brake fluid level), steering system data (for example: steering angle, steering assist status), body control data (for example: door status, window status, light status, wiper status), safety system data (for example: airbag status, anti-lock braking system status, electronic stability control system status), in-vehicle entertainment and information system data (for example: navigation system status, multimedia system status, Bluetooth connection status), etc.

[0040] Perception data refers to environmental information obtained through vehicle-mounted sensors and is used to perceive the environment and objects around the vehicle. Such data is usually generated by various sensors (such as cameras, radars, laser radars, ultrasonic sensors, etc.) and transmitted to the vehicle-mounted terminal 110 via the vehicle-mounted Ethernet.

[0041] Common perception data types may include: visual sensor data (for example: camera images, depth images, semantic segmentation images), radar data (for example: distance, speed and angle of target objects, multi-target tracking data), lidar data (for example: point cloud data, contour and shape information of target objects), ultrasonic sensor data (for example: distance and position of close-range obstacles), measurement unit data (for example: acceleration (three-axis), angular velocity (three-axis), attitude angle (such as pitch angle, roll angle, heading angle)), global positioning system data (for example: longitude and latitude, altitude, speed and direction), environmental sensor data (for example: temperature, humidity, air pressure, light intensity), etc., and the embodiments of the present invention are not limited to this.

[0042] After obtaining the operation perception data, the vehicle-mounted terminal 110 may store the operation perception data, or may send the obtained operation perception data to the data aggregation platform 120 for storage.

[0043] Specifically, the data aggregation platform 120 may be deployed on a cloud platform. The data aggregation platform 120 may be responsible for receiving the operation perception data uploaded by the vehicle-mounted terminal 110 and performing data storage, analysis, and other processing on the operation perception data.

[0044] The data aggregation platform 120 can provide an API to the outside world and provide data services to the outside world through the API; specifically, the supervision platform 130 can obtain the operation perception data of the intelligent connected vehicle from the data aggregation platform 120 through the application development interface, and perform subsequent processing. The embodiment of the present invention does not limit the subsequent processing.

[0045] In order to ensure the security of data sent by the vehicle-mounted terminal 110 to the data aggregation platform 120, the vehicle-mounted terminal 110 can encrypt the operation perception data; specifically, in order to avoid the vehicle-mounted terminal 110 being unable to complete the encryption operation due to insufficient performance, the embodiment of the present invention can adopt a lightweight encryption algorithm. For example, the vehicle-mounted terminal 110 can adopt an advanced encryption standard algorithm with a 6-round encryption process to encrypt the operation perception data.

[0046] After completing the encryption of the operation perception data, the vehicle-mounted terminal 110 can send the encrypted operation perception data to the data aggregation platform 120; after obtaining the encrypted operation perception data, the data aggregation platform 120 can decrypt the encrypted operation perception data, and perform local storage, analysis, processing and other operations on the decrypted operation perception data.

[0047] The supervision platform 130 can obtain the decrypted operation perception data and the processed operation perception data from the data aggregation platform 120 by accessing the application development interface, which is not limited in this embodiment of the present invention.

[0048] In the embodiment of the present invention, the intelligent networked vehicle management system 10 may include: an on-board terminal 110, a data aggregation platform 120 and a supervision platform 130; wherein: the on-board terminal 110 is installed on the intelligent networked vehicle, and the on-board terminal 110 is used to collect the operation perception data of the intelligent networked vehicle, and encrypt the operation perception data using the advanced encryption standard algorithm of the 6-round encryption process, and send it to the data aggregation platform 120; the data aggregation platform 120 is used to receive the encrypted operation perception data and decrypt the encrypted operation perception data; the data aggregation platform 120 provides an application development interface to the outside world, and provides data services through the application development interface; the supervision platform 130 is used to obtain the operation perception data from the data aggregation platform 120 by accessing the application development interface. The embodiment of the present invention reduces the encryption process to 6 rounds, and reducing the number of encryption rounds can significantly reduce the computing burden of the on-board terminal 110.

[0049] In one embodiment of the present invention, in the advanced encryption standard algorithm of the 6-round encryption process, each round includes byte replacement, row shift and round key addition.

[0050] In some feasible embodiments, in the advanced encryption standard algorithm of the 6-round encryption process, each round includes four steps: byte replacement (SubBytes), row shift (ShiftRows), column confusion (MixColumns) and round key addition (AddRoundKey). These steps together ensure the high security of the AES algorithm. In order to adapt to the resource-constrained vehicle terminal 110 environment, the improved lightweight AES encryption method of the present invention simplifies these steps to improve performance.

[0051] Specifically, the MixColumns step is a key part of the AES algorithm, which is responsible for increasing the diffusion between columns, that is, each byte in one column affects the bytes in other columns. This diffusion is one of the key features of AES to resist linear and differential attacks. Although removing the MixColumns step will reduce the diffusion between columns, which will reduce the algorithm's ability to resist certain types of attacks, other steps (such as byte replacement and row shift) are still retained, and the algorithm can still provide fairly high security.

[0052] It can be seen that removing the MixColumns step can significantly reduce the computational burden of the vehicle terminal 110, especially when processing large amounts of data. This not only reduces processing time and energy consumption, but also maintains an acceptable level of security for the resource-constrained vehicle terminal 110 environment.

[0053] Therefore, in the embodiment of the present invention, in the advanced encryption standard algorithm of the 6-round encryption process, each round includes byte replacement, row shift and round key addition, but no column confusion.

[0054] In one embodiment of the present invention, the vehicle-mounted terminal 110 is used to encrypt the operation perception data by using an advanced encryption standard algorithm including a 6-round encryption process of byte replacement, row shifting and round key addition when the computational burden of the vehicle-mounted terminal 110 meets the preset conditions; when the computational burden of the vehicle-mounted terminal 110 does not meet the preset conditions, the operation perception data is encrypted by using an advanced encryption standard algorithm including a 6-round encryption process of byte replacement, row shifting, column obfuscation and round key addition.

[0055] In some feasible embodiments, the specific encryption algorithm to be adopted may also be decided based on the current computing load of the vehicle terminal 110; specifically, a preset condition may be set, which may be used to determine whether the current computing load of the vehicle terminal 110 is overloaded.

[0056] Exemplarily, if the current computing burden of the vehicle terminal 110 meets the preset conditions, it can be determined that the computing burden of the vehicle terminal 110 is overloaded; at this time, the vehicle terminal 110 can use an advanced encryption standard algorithm including a 6-round encryption process of byte replacement, row shifting and round key addition to encrypt the running perception data, that is, use an encryption algorithm that does not include column confusion.

[0057] On the contrary, if the current computing burden of the vehicle terminal 110 does not meet the preset conditions, it can be determined that the computing burden of the vehicle terminal 110 is not overloaded; at this time, the vehicle terminal 110 can use an advanced encryption standard algorithm including a 6-round encryption process of byte replacement, row shift, column confusion and round key addition to encrypt the running perception data, that is, maintain column confusion in the encryption algorithm.

[0058] In one embodiment of the present invention, in byte replacement, a 256-byte lookup table is pre-computed to map input bytes to output bytes.

[0059] In some feasible embodiments, the byte replacement step in the standard AES algorithm involves an S-Box that maps each byte to another byte. This S-Box is obtained by multiplying the byte with a fixed polynomial on a Galois field and then by a fixed nonlinear transformation. In order to simplify this step, an embodiment of the present invention can pre-calculate a 256-byte lookup table to directly map the input bytes to the output bytes. The pre-calculated lookup table can be used to reduce the complexity of the calculation process and improve efficiency. In the improved lightweight AES encryption method of the present invention, the lookup table can be used for byte replacement (SubBytes) and key scheduling (Key Schedule).

[0060] In one embodiment of the present invention, in the advanced encryption standard algorithm of the 6-round encryption process, the key scheduling is performed by creating a lookup table for multiplication on the Galois field and creating another lookup table for rotation operation.

[0061] In some feasible embodiments, the key arrangement of the standard AES algorithm involves the generation of round keys, which requires the use of multiplication and rotation operations on the Galois field. These operations can be simplified by pre-calculated lookup tables. For example, a lookup table can be created for multiplication on the Galois field, and another lookup table can be created for rotation operations. The specific implementation process is: before the algorithm is implemented, the required lookup table is pre-calculated and stored. Then, during the execution of the AES algorithm, when byte replacement or key arrangement is required, the lookup table is directly queried to obtain the result. This method avoids complex mathematical operations at runtime, thereby improving the execution speed of the algorithm. It should be noted that although the lookup table needs to be stored in the memory of the vehicle terminal 110, because the size of the lookup table is relatively small, although the resources of the vehicle terminal 110 are limited, it is also within an acceptable range.

[0062] In one embodiment of the present invention, the vehicle terminal 110 is used to adjust the frequency and amount of data upload to the data aggregation platform 120 according to the storage status of the vehicle terminal 110 and the network status between the vehicle terminal 110 and the data aggregation platform 120.

[0063] In some feasible embodiments, the vehicle terminal 110 can upload the encrypted operation perception data to the remote data aggregation platform 120 through a wireless network. In practical applications, the upload strategy can be implemented in an intelligent scheduling manner. Specifically, the vehicle terminal 110 can dynamically adjust the frequency and amount of data upload to the data aggregation platform 120 according to the storage status of the vehicle terminal 110 and the network status between the vehicle terminal 110 and the data aggregation platform 120 to reduce the possibility of data loss.

[0064] Specifically, the vehicle terminal 110 will monitor the network status between the vehicle terminal 110 and the data aggregation platform 120 in real time. The network status may include signal strength, bandwidth, delay, packet loss rate, etc.

[0065] When the network status is good, the vehicle terminal 110 will increase the data upload frequency and data upload amount to fully utilize network resources; when the network status is poor, the vehicle terminal 110 will reduce the data upload frequency and data upload amount to reduce the risk of data loss and transmission failure.

[0066] At the same time, the vehicle terminal 110 will monitor the usage of the storage space of the vehicle terminal 110. When the storage space is close to full, the vehicle terminal 110 will increase the frequency of data upload to free up storage space; when the storage space is sufficient, the vehicle terminal 110 can reduce the frequency of data upload to save network resources.

[0067] In some feasible embodiments, the vehicle terminal 110 monitors the network status and storage status in real time through built-in sensors or software tools. Specifically, the present invention uses Wireshark to capture and analyze network data packets to help monitor network traffic and data packet loss; uses ping / traceroute to test network connectivity and routing paths to quickly identify network delays and connection problems; uses iftop to display the traffic and connection of the network interface in real time to help monitor network traffic and identify traffic anomalies; and uses iperf to measure network bandwidth and evaluate network performance and bandwidth capacity.

[0068] In an embodiment of the present invention, the vehicle-mounted terminal 110 is used to upload the operation perception data to the data aggregation platform 120 according to the priority of the operation perception data.

[0069] In some feasible embodiments, the data may also be classified in advance; then, the vehicle terminal 110 may upload the operation perception data to the data aggregation platform 120 according to the priority of the encrypted operation perception data currently required to be transmitted. Specifically, the operation perception data with a high priority may be uploaded to the data aggregation platform 120 first, and the embodiment of the present invention does not limit this.

[0070] In the embodiment of the present invention, the combination of multiple tools can be used to monitor and analyze network conditions more comprehensively and accurately. Then, based on the monitored information, the vehicle terminal 110 will dynamically adjust the upload strategy, including adjusting the upload time interval, data packet size or upload queue priority, and continuously optimize the upload strategy based on real-time feedback through an adaptive mechanism.

[0071] In one embodiment of the present invention, the vehicle terminal 110 is further used to determine a first checksum of the operation perception data, and send the first checksum along with the operation perception data to the data aggregation platform 120;

[0072] The data aggregation platform 120 is used to determine a second checksum based on the received operation perception data; and to check the received operation perception data based on the first checksum and the second checksum.

[0073] In some feasible embodiments, the data supervision platform 130 is deployed on a cloud platform, responsible for receiving the encrypted data uploaded by the vehicle terminal 110, storing, analyzing and processing the decrypted data, and providing data services to the outside through an API. Specifically, the data supervision platform 130 obtains the key for decryption from a predefined storage or key management system, and uses the decryption key to decrypt the received encrypted data. The decryption process includes steps such as reverse byte replacement, reverse row shifting, and reverse round key addition to restore the original data.

[0074] During the decryption process, the data supervision platform 130 will perform error detection and correction simultaneously; specifically, before the vehicle terminal 110 sends data, a first checksum can be calculated based on the operation perception data.

[0075] The checksum is calculated by breaking the data into fixed-length segments and then performing a mathematical operation (such as addition or XOR) on each segment.

[0076] Then, the vehicle terminal 110 sends the encrypted operation perception data and the first checksum to the data supervision platform 130 .

[0077] After receiving the data sent by the vehicle terminal 110, the data supervision platform 130 first decrypts the encrypted operation perception data; then, calculates the second checksum based on the decrypted operation perception data, and compares the first checksum and the second checksum to verify the received operation perception data.

[0078] If the checksum does not match, it means that the data may be erroneous or damaged during the transmission process. At this time, the data supervision platform 130 will send a request to the vehicle terminal 110, asking it to resend the data. After receiving the retransmission request, the vehicle terminal 110 will resend it.

[0079] After decryption, the data can be further processed on the data supervision platform 130, such as storage, analysis, display, etc., and data services can be provided externally through APIs. When providing data services externally, the data transmission process may involve encryption again to ensure the security of the data during transmission. After the supervision platform 130 receives the data, it can be decrypted again if necessary. The decryption process is similar to the decryption process of the data supervision platform 130, and the corresponding decryption key needs to be used.

[0080] The supervision platform 130 obtains the operation perception data by accessing the API interface of the data supervision platform 130. The supervision platform 130 stores, analyzes and displays the acquired data, and realizes the interaction function with the user. The analysis and display functions of the supervision platform 130 should support real-time monitoring and historical data backtracking, so that supervisors can respond and make decisions in a timely manner.

[0081] Based on the intelligent networked vehicle management system mentioned in the above embodiment, an embodiment of the present invention further provides a data transmission method, which can be applied in the intelligent networked vehicle management system.

[0082] like Figure 2 As shown, Figure 2 A flow chart showing a method for transmitting data according to an embodiment of the present invention may include the following steps:

[0083] Step 201: collect the operation perception data of the intelligent network-connected vehicle, and encrypt the operation perception data using the Advanced Encryption Standard algorithm with a 6-round encryption process.

[0084] In order to ensure the security of data sent by the vehicle-mounted terminal to the data aggregation platform, the vehicle-mounted terminal can encrypt the operation perception data; specifically, in order to avoid the vehicle-mounted terminal being unable to complete the encryption operation due to insufficient performance, the embodiment of the present invention can adopt a lightweight encryption algorithm. Exemplarily, the vehicle-mounted terminal can use an advanced encryption standard algorithm with a 6-round encryption process to encrypt the operation perception data.

[0087] The supervision platform can obtain the decrypted operation perception data and the processed operation perception data from the data aggregation platform by accessing the application development interface, and the embodiment of the present invention does not limit this.

[0088] In the embodiment of the present invention, the operation perception data of the intelligent networked vehicle is collected, and the operation perception data is encrypted using the advanced encryption standard algorithm of the 6-round encryption process; the encrypted operation perception data is sent to the data aggregation platform; the data aggregation platform is used to receive the encrypted operation perception data and decrypt the encrypted operation perception data; the data aggregation platform provides an application development interface to the outside world and provides data services through the application development interface; the supervision platform is used to obtain the operation perception data from the data aggregation platform by accessing the application development interface.
