Abstract

The invention discloses a password generating method and device and a smart lock. The method comprises the steps: acquiring a serial number of the smart lock; carrying out encryption operation on the serial number of the smart lock by using a preset initial key, so as to obtain a key of the smart lock; acquiring a password group serial number input by a user; filling the password group serial number, so as to obtain a digit group of the password group serial number; carrying out encryption operation on the digit group of the password group serial number by using the key of the smart lock, thereby obtaining a first dynamic password. According to the password generating method and device and the smart lock, the technical problem in the prior art that the password safety performance of the smart lock is low is solved.

Description

technical field [0001] The present invention relates to the field of smart locks, and in particular, to a password generation method, device and smart lock. Background technique [0002] The smart lock used with the metering box is very common at present. Because the smart lock can use the password input method to verify the user's identity, it solves the inconvenience of carrying the key and the risk of losing the key. [0003] The password of the existing smart lock often adopts the smart lock password keyboard, 3des key algorithm or key dispersion technology, and the password is stored in the EEPROM of the smart lock. The password used is fixed and needs to be added, deleted, and modified by the user. ; Passwords that can modify other passwords are called super passwords; and passwords are generally composed of 6 digits, that is to say, there are at most 1 million groups of passwords; since the passwords are fixedly stored in the EEPROM chip, and the password groups that ...
