Problems solved by technology
Fixed passwords (such as "111") are fixed, so this type of password is easy to be cracked and stolen. A password that can be manually modified means that the user needs to manually update the password. If the modification is infrequent, then it will also be There is a risk of being cracked
And if the modification is too frequent, it will cause the user's memory burden, and it is easy for the user to forget the password
If an electrical system contains multiple identical electrical devices, the uncertainty of manually changing the password may lead to different passwords for each electrical device, which also brings trouble to the management of the electrical system

The invention discloses a password generation method for electrical equipment. The password generation method comprises the following steps: 1, acquiring real-time data of a preset natural variable related to the electrical equipment; 2, performing data processing on the real-time data of the preset natural variable, and extracting password source data from the real-time data; and 3, generating adynamic password for the electrical equipment according to the password source data. According to the method, the password is naturally changed by introducing the real-time data of the preset naturalvariable related to the electrical equipment such that manual intervention in the prior art is not needed. Meanwhile, according to the method, simple processing and subsequent simple calculation or combination are carried out through the real-time data of the preset natural variable such that the complexity of the finally obtained dynamic password is improved, and the anti-cracking capability of the dynamic password is also improved.
Description
technical field [0001] The invention relates to the technical field of security encryption, in particular to a method and device for generating a password for electrical equipment. Background technique [0002] In order to protect certain important operations from misoperation or malicious operation, electrical equipment usually hides this part of the content. These important operations can only be performed after the user enters the correct password or performs the correct combination of operations (unlocking is successful). [0003] Existing passwords generally include fixed passwords and passwords that can be manually modified. Fixed passwords (such as "111") are fixed, so this type of password is easy to be cracked and stolen. A password that can be manually modified means that the user needs to manually update the password. If the modification is infrequent, then it will also be There is a risk of being cracked. And if the modification is too frequent, it will cause ...
