[0043] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0045] In a first aspect, an embodiment of the present application provides a method for flashing a host computer.
[0046] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the method for flashing a host computer to implement this application. Figure 1 As shown, the method for flashing the host computer includes:
[0047] Step S10: construct a flashing basic framework, wherein the flashing basic framework is used to perform the flashing action.
[0048] For example, in this embodiment, a flashing basic framework is first constructed, and the flashing basic framework is mainly responsible for executing the flashing of the factory program; wherein, the flashing basic framework includes but is not limited to a user interface layer, a business logic layer and a communication protocol layer, the user interface layer is used to provide a user interaction interface, such as setting flashing parameters, selecting flashing files, monitoring flashing progress and displaying alarm information through the user interface layer, the business logic layer is used to implement communication protocol processing, data verification, flashing process control and error handling, etc., the communication protocol layer is used for the protocol for communicating with the lower computer, etc.; it should be noted that since the specific composition and implementation principle of the flashing basic framework are common knowledge in the field, they will not be repeated here for the sake of brevity of description.
[0049] Step S20: embed a black box module including a seed input interface and a key output interface in the flashing basic framework to generate a target flashing host computer; wherein the black box module is used to access the dynamic link library file corresponding to the security algorithm, the seed input interface is used to receive the target seed input by a third-party user, so that the dynamic link library file generates a target key based on the target seed, the target seed is provided by the target controller in the electric drive assembly to be flashed, and the key output interface is used to output the target key to the target controller, so that the target controller can perform security verification based on the target key.
[0050] For example, it should be understood that although the security algorithm of each customer is different, the flashing process is consistent, so this embodiment will provide a flashing host computer that can accommodate different security algorithms through a flashing process. In order to avoid the leakage of security algorithms, this embodiment will embed a black box module whose data processing process and principle are invisible to the outside in the flashing host computer to determine whether the flashing basic framework will flash the factory program, so that the third-party user can complete the development of the target flashing host computer without providing the security algorithm to the supplier.
[0051] Specifically, the black box module embedded in the flashing basic framework only needs to provide a seed input interface (i.e., SEED interface) and a key output interface (i.e., KEY interface), that is, the black box module in the target flashing host computer developed by the supplier is empty and does not integrate a security algorithm; only after the supplier sends the target flashing host computer to the third-party user responsible for the factory program flashing, the third-party user can access the dynamic link library file (i.e., .dll file) that integrates the security algorithm corresponding to the electric drive assembly to be flashed through the black box module when using the target flashing host computer to flash the target customer's electric drive assembly to be flashed, and perform security verification through the .dll file. It should be understood that the storage location of the .dll file is only known to the third-party user and the target customer, but not to the supplier, that is, the supplier cannot access the .dll file through the black box module.
[0052] Among them, when accessing the dynamic link library file corresponding to the security algorithm through the black box module, it is first necessary to receive the target seed input by the third-party user through the seed input interface, and the target seed is provided by the target controller in the electric drive assembly to be flashed; then access the .dll file through the black box module to perform key calculation on the target seed through the security algorithm integrated in the .dll file, and then generate the target key; then output the target key to the target controller through the key output interface, so as to perform security verification on the target key output by the black box module through the target controller to determine whether the program can be flashed, thereby improving the security of the flashing.
[0053] It should be understood that this embodiment will provide different seed input interfaces and key output interfaces for different customers, so as to input seeds corresponding to different security algorithms and output keys corresponding to different security algorithms. For example, for a third-party user, there are target customers A, B and C. The seed input interface and key output interface corresponding to customer A are SEED_1 and KEY_1 respectively, the seed input interface and key output interface corresponding to customer B are SEED_2 and KEY_2 respectively, and the seed input interface and key output interface corresponding to customer C are SEED_3 and KEY_3 respectively; therefore, when a third-party user needs to flash the program for the electric drive assembly to be flashed for customer A, the SEED_1 interface is first called to input the seed, and then the KEY_1 interface is called to output the key, so as to realize the security verification of customer A.
[0054] Among them, it is assumed that the security algorithm 1 of customer A is the input value × 4. If the seed 1 input through the SEED_1 interface is 5, then when accessing the .dll file 1 corresponding to the security algorithm 1, the key 5×4=20 will be calculated based on the security algorithm 1 and the seed 1; then the key "20" is transmitted to the controller in the electric drive assembly to be flashed by customer A through the KEY_1 interface, so as to perform a security check on the key based on the controller.
[0055] It can be seen that in this embodiment, the supplier can realize the development of flashing the upper computer by embedding the black box module, so that the third-party user does not need to provide the security algorithm to the supplier, that is, the security algorithm does not need to be made public, and the "security" verification is truly realized; and the third-party user can access the dynamic link library file that integrates different security algorithms through the black box module and perform security verification, thereby effectively improving the development security of the flashing upper computer and reducing the development cost.
[0056] Furthermore, in one embodiment, after the step of embedding a black box module including a seed input interface and a key output interface in the flashing basic framework to generate a target flashing host computer, the method further includes:
[0057] When the target flashing host computer receives the target seed and the target access address corresponding to the dynamic link library file input by the third-party user, the black box module is controlled to parse the target access address to obtain the target access path;
[0058] Controlling the black box module to access the dynamic link library file based on the target access path, so as to perform key calculation on the target seed through the security algorithm carried in the dynamic link library file to generate a target key;
[0059] The target key is transmitted to the target controller so that the target controller can perform a security check based on the target key and a preset key pre-generated in the target controller, and control the flashing of the target flashing host computer according to the security check result.
[0060] Exemplarily, in this embodiment, the embedded black box module will be address-interfaced, that is, a third-party user can enter the access address (i.e., target access address) of the .dll file corresponding to the security algorithm to be accessed and the target seed provided by the target controller in the electric drive assembly to be flashed on the interface; when the target flashing host computer receives the target access address, it will control the black box module to parse the target access address to obtain the target access path; then the black box module can start accessing the .dll file according to the target access path. For example, assuming that the target access path is D drive → F folder → F1 folder → F11 folder → .dll file, the black box module can complete the access to the dynamic link library file in the order of accessing D drive, F folder, F1 folder, F11 folder and .dll file in sequence.
[0061] The target key can be generated by calculating the key of the target seed through the security algorithm in the .dll file; then the target key is transmitted to the target controller through the KEY interface. The target controller can then perform a security check based on the target key and its own pre-generated key, and determine whether the target flashing host computer can flash the factory program to the target controller based on the security check result, so as to ensure the security of program flashing.
[0062] It should be noted that, although the security algorithms corresponding to different customers are inconsistent, in the target flashing host computer provided in this embodiment, third-party users only need to independently modify the embedding path of the .dll file corresponding to the security algorithm to realize the development of the flashing host computer for new customers, thereby effectively shortening the development cycle of the flashing host computer required for new customers and reducing development costs. In addition, during the entire development process, except for the customers, other developers do not need to know the specific security algorithm, and the process is safer.
[0063] Further, in one embodiment, the target controller performs security verification based on the target key and a preset key pre-generated in the target controller, including:
[0064] The target controller determines whether the target key is consistent with a preset key, where the preset key is obtained by the target controller performing key calculation on the target seed based on the security algorithm;
[0065] If the target key is consistent with the preset key, it is determined that the security check has passed;
[0066] If the target key is inconsistent with the preset key, it is determined that the security check fails.
[0067] For example, see Figure 2As shown, before a third-party user needs to flash the program of the target controller in the electric drive assembly to be flashed, the third-party user must first request the target controller to obtain the seed SEED; when the target controller receives the request, it will randomly generate a SEED, and calculate the key for the randomly generated SEED according to its internal security algorithm to obtain the preset key, and send the randomly generated SEED to the third-party user at the same time; then the third-party user inputs the SEED into the black box module through the SEED interface to access the corresponding .dll file through the black box module, and then calculates the target key corresponding to the SEED through the security algorithm in the .dll file; finally, the target key is transmitted back to the target controller through the KEY interface, and the target controller can perform a security check based on the consistency between the target key and the preset key, that is, if the two are consistent, the security check is determined to be passed, and if the two are inconsistent, the security check is determined to be failed.
[0068] It should be understood that the seed SEED is randomly generated by the target controller, that is, the seed SEED is dynamic, which can avoid the problem of SEED or key leakage. Therefore, security verification based on the randomly generated SEED can further improve the security of flashing.
[0069] Furthermore, in one embodiment, the step of controlling the flashing of the target flashing host computer according to the security verification result includes:
[0070] If the security check result is passed, the target flashing host computer is controlled to perform a flashing action on the target controller;
[0071] If the safety check result is not passed, the target flashing host computer is controlled to end the flashing process of the target controller.
[0072] Exemplarily, in this embodiment, when the target controller confirms that the target key is the same as the preset key, it means that the flashing of the target flashing host computer this time is legal and safe, and then the information that the security check passed is sent to the target flashing host computer so that the target flashing host computer can perform the flashing operation on the target controller; however, if the target key is not the same as the preset key, it means that there is a security problem in the flashing of the target flashing host computer this time, and then the information that the security check failed is sent to the target flashing host computer so that the target flashing host computer ends the flashing process of the target controller.
[0073] The following combination Figure 3 The process and principle of program flashing on the target flashing host computer provided in this embodiment are explained.
[0074] First, a third-party user obtains a target seed corresponding to a security algorithm from a target controller in a certain customer's electric drive assembly to be flashed (for example, the SEED corresponding to customer A is 5); secondly, the target seed and the target access address of the dynamic link library file corresponding to the security algorithm are input into the black box module; the black box module accesses the dynamic link library file through the target access address, and calculates the key for the target seed based on the security algorithm in the dynamic link library file (for example, the security algorithm of customer A is input to ×4), and obtains the corresponding target key (for example, the target key corresponding to customer A is 20); when the target controller detects that the target key is consistent with the preset key, the target software to be flashed is downloaded, and the content to be flashed in the target software is gradually written into the target controller through the target flashing host computer; after the flashing is completed, the version number data corresponding to the last line in the target controller can be compared with the preset version number. If the two are the same, it is confirmed that the flashed target software is correct; otherwise, it is determined that the flashed target software is wrong and needs to be flashed again.
[0075] In summary, the security check provided by the target flashing host computer of this embodiment is similar to that of an electronic door lock, and the security algorithms set by different customers, that is, the door opening passwords of electronic door locks, are different and dynamic. Therefore, only by entering the correct password can the formal flashing interaction begin, that is, if the flashing device can calculate the corresponding correct key, the door will open, and the next step of interaction can be achieved; it can be seen that this embodiment can allow the supplier to complete the development of the flashing host computer without providing the security algorithm to the supplier, making the flashing host computer a "universal key", but without deciphering the security algorithm, so as to make the development process safer; in addition, it is only necessary to build a line for the supplier to develop a prototype of the flashing host computer once, and subsequently for all new customers, third-party users can independently complete the program development of the flashing host computer, which can save a lot of costs and shorten the development cycle for platform-based production lines (pure electric five-wire and pure electric six-wire).
