Embodiment Construction

[0021] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] This embodiment proposes a vehicle information system rights management method based on login prompt codes and remote decoding, including the following steps:

[0023] S1. Generation and display of login prompt code

[0024] In the process of logging into the vehicle information system, the random number generating function is used to generate a login prompt code, and the user is required to provide the login password corresponding to the prompt code, such as figure 1 shown. The length of the prompt code is variable according to the security requirements of the system authority. figure 1 The length of the hint code is 6 digits.

[0025] S2. Encryption design

[0026] According to different authority security ...

Abstract

The invention provides a vehicle information system authority management method based on a login prompt code and remote decoding, and the method comprises the steps: generating the login prompt code through a random number generation function in a process of logging in a vehicle information system, and requesting a user to provide a login password corresponding to the prompt code; calculating the login prompt code by adopting an encryption algorithm to serve as a final check password; calculating the login prompt code fed back by the user on the computer by using the same encryption algorithm to obtain a login password, and displaying the login password in a login password box; and inputting the obtained login password on the login interface of the vehicle information system, if the login password is consistent with the check password, indicating that the login is passed, and enabling the user to obtain the operation authority, otherwise, not allowing the user to log in. According to the method, the permission use flexibility can be ensured, and meanwhile, the technical problem of permission abuse caused by infinite expansion of the permission range is avoided.

Description

technical field [0001] The invention belongs to the technical field of vehicle information systems, and in particular relates to a vehicle information system rights management method based on login prompt codes and remote decoding. Background technique [0002] At present, the human-computer interaction of the vehicle information system has no authority management, and can be directly logged in, or managed through a fixed password, and the user can use it for a long time after obtaining the password, and even obtain the use authority of other vehicles after obtaining the password of one vehicle . However, if the use authority is strictly controlled, the password is only in the hands of a few people, which will also cause inconvenience in use. If all users can easily obtain the authority, setting the use authority will also be meaningless. [0003] In view of the current trend of more and more human-computer interaction devices in vehicle information systems, more and more c...
