Fig. 1 is a flowchart of an apparatus diagnosis method according to an embodiment of the present invention, where the present embodiment is applicable to a scenario of diagnosing an apparatus, the method may be executed by an apparatus diagnosis device, the apparatus diagnosis device may be implemented in a form of hardware and/or software, and the apparatus diagnosis device may be configured in an electronic apparatus such as a computer or a server.
As shown in fig. 1, the method of the present embodiment includes:
s110, in the process of diagnosing the equipment, when the initial security access method is executed, determining a target security access method corresponding to the initial security access method.
A device is understood to mean a device to be diagnosed, for example a motor vehicle, an electric vehicle or an aircraft. In an embodiment of the present invention, the devices to be diagnosed may be devices produced by different host factories having the same diagnostic specifications. The number of devices may be one, two or more. The initial security access method may be understood as a security access algorithm that needs to be executed by default in the process of diagnosing the device. It should be noted that the initial security access methods corresponding to the devices with the same diagnostic specifications, which are produced by different host factories, may be the same or different. The target security access method can be understood as a preset security access method which needs to be executed in the process of diagnosing the equipment. In an embodiment of the invention, each device produced by a different host factory has the same diagnostic specification. In the process of diagnosing each device, when the initial secure access method corresponding to each device is executed, the target secure access method corresponding to each initial secure access method may be determined based on a correspondence between a preset initial secure access method and a target secure access method.
In the embodiment of the invention, the target security access method is obtained by the following method:
and performing method translation processing on the initial security access method based on a preset programming language to obtain the target security access method.

It should be noted that, in the embodiment of the present invention, the code file storing the target secure access method is relatively independent from the code file for diagnosing the device. In practical applications, the code file storing the target secure access method can be flexibly created, that is, the code corresponding to the target secure access method is a flexibly created code, and the codes can be assembled during operation or in the operation process without being linked with the code for diagnosing the device.
And S120, loading the target security access method, and executing the loaded target security access method based on a reflection mechanism.
Specifically, after the target security access method is determined, the target security access method may be loaded to the memory. The loaded target secure access method may then be executed based on the reflection mechanism reflection. The reflection-based execution of the loaded target security access method may be understood as that, when the initial security access method is executed, a default diagnostic execution flow is changed, and the target security access method is executed in a reflection manner. That is, the transition is from executing the initial secure access method to executing the target secure access method.

Optionally, after the initial secure access method is translated based on a preset programming language, the method includes: and encrypting the translated method, and taking the encrypted method as a target security access method.

After the translated method is obtained, the translated method can be encrypted through a preset encryption algorithm. Thus, the method after the encryption processing can be obtained, and in this case, the method after the encryption processing can be used as the target secure access method. By doing so, the security of the target secure access method can be improved, and the secure access method can be prevented from being maliciously attacked or tampered.
Alternatively, the preset Encryption algorithm may include a symmetric Encryption algorithm (DES algorithm). The encryption processing of the translated method comprises the following steps: and based on a symmetric encryption algorithm, carrying out encryption processing on the translated method. It should be noted that, in the embodiment of the present invention, the symmetric encryption algorithm is used to perform encryption processing on the method, which not only has small calculation amount, fast encryption speed and high encryption efficiency, but also has high cracking difficulty. The safety of the method is further improved.

Specifically, a target secure access method is loaded. At this time, the loaded target secure access method is an encrypted target secure access method. Then, after the encrypted target security access method is loaded, the encrypted target security access method may be decrypted based on a decryption algorithm corresponding to the preset encryption algorithm. So that a decrypted method can be obtained. The decrypted method is then executed based on a reflection mechanism.
Optionally, after the encrypting the translated method and taking the encrypted method as a target secure access method, the method further includes: and storing the target security access method into a text file with a preset format.
The preset format may be a format of a text file for storing the target security access algorithm, which is set according to actual requirements. Illustratively, the preset format may be a txt format.
In one embodiment, after obtaining the target access method, it is understood that after obtaining the code of the target method, the code of the target access method may be stored in a text file in a pre-established preset format. On the basis, the loading of the target secure access method comprises the following steps: and reading the target security access method from the text file, and loading.
In order to facilitate more rapid and effective invoking of the target secure access method, after reading the target secure access method from the text file, the method further includes: and dynamically compiling the target security access method to generate a security access executable file.
The security access executable file may be an executable file generated by dynamically compiling codes of the target security access method. Optionally, the file format of the secure access executable file may be a dll format file.
In this embodiment of the present invention, the dynamic compiling process for the target secure access method includes: and reading the target security access method from the text file by calling a predefined method compiling class, and performing dynamic compiling processing.
The predefined method compilation classes may include, but are not limited to, the ChalopCoprovider class, the ComilerParameters class, and the ComilerResults class, among others.
