In this embodiment, S207 to S210 and S102 to S105 in the above embodiment may be referred to each other, and are not described herein again.
Since the authentication can be completed through the local historical authentication record, i.e. the target identification information, in the absence of a network, if the user tampers with the local target identification information and adds the identification information which is historically authenticated, the identification information which is not authenticated will be authenticated. Therefore, in order to avoid such a situation, the present application provides a specific authentication method for an automobile diagnostic device.
A specific method for authenticating the vehicle diagnostic device provided in the embodiments of the present application is described below, and a specific vehicle diagnostic device described below and the above embodiments may be referred to each other.

In the scheme, if the target identification information is determined to include the identification information to be authenticated, further verification is needed, namely, whether an authorization file corresponding to the identification information to be authenticated exists is verified. It should be noted that, the automobile manufacturer allows the diagnostic device to perform an authorization certification for offline authentication, and in the authorization file, the identification information of the computer device and the identification information of the corresponding automobile diagnostic device are recorded. If the identification information to be authenticated corresponds to the authorization file, it is proved that the identification information to be authenticated is allowed by the manufacturer to complete the offline authentication, S405 is executed, otherwise, the manufacturer does not authorize the diagnostic equipment corresponding to the identification information to be authenticated to complete the offline authentication, and S406 is executed. Therefore, the management of offline authentication by manufacturers can be realized.
In a specific implementation manner, the determining whether the computer device stores an authorization file corresponding to the identification information to be authenticated includes: decrypting all ciphertext authorization files stored by the computer equipment to obtain corresponding plaintext authorization files; and judging whether an authorization file corresponding to the identification information to be authenticated exists in all the plaintext authorization files.
In the scheme, the authorization file is also encrypted, so that the ciphertext of the authorization file is locally stored, the user is prevented from tampering the authorization file, and the reliability of authentication is ensured.
In another specific embodiment, if the authorization file further includes an authorization validity period, before the step of determining that the to-be-authenticated automobile diagnostic device passes the authentication, the method further includes:

It should be noted that, in order to prevent the user from using the vehicle diagnostic device indefinitely without the network, in the present embodiment, an authorization validity period is added to the authorization file, so as to limit the period for which the vehicle diagnostic device can be used without the network. It should be noted that, since the vehicle diagnostic device needs to perform the authentication operation before each use, the effect of limiting the period of using the vehicle diagnostic device by the user without a network can be achieved by determining whether the vehicle diagnostic device is within the authorized validity period during the authentication.
It should be noted that, if the current time exceeds the authorization validity period in the authorization file, after determining that the authentication of the fault diagnosis device fails, the corresponding authorization file is deleted, so that when the authorization file is authenticated again, the corresponding authorization file is directly authenticated as failed.
S405, determining that the to-be-authenticated automobile diagnosis equipment passes authentication.
