Safe box with dynamic password function

Abstract

The invention relates to a safe box with a dynamic password function. The safe box is provided with a box body, an electronic lock and a controller, wherein the electronic lock is configured to receive an unlocking signal from the controller so that unlocking can be achieved; and the controller is configured to execute the following actions of receiving a first dynamic password from a user which is generated by a cipherer through a first seed and an encryption algorithm under the condition that the user is legal, generating a second dynamic password through the first seed and the encryption algorithm, comparing the first dynamic password with the second dynamic password, and sending the unlocking signal to the electronic lock under the condition that the first dynamic password and the second dynamic password are consistent. The invention further relates to an operating method of the safe box. By means of the safe box or the method, safety can be improved by using the dynamic passwords,meanwhile, a complex decryption procedure can be avoided, and thus the structure of the controller is simplified and cost is lowered.

Description

technical field [0001] The present invention generally relates to the security field, and in particular relates to a safe with a dynamic password function and a method for operating such a safe. Background technique [0002] With the improvement of living standards and the accumulation of personal wealth, the custody of personal property has increasingly become a concern of people. Therefore, safes have gradually entered the lives of the public. [0003] Conventional safes generally adopt traditional locks such as mechanical locks, combination locks and fingerprint locks, etc., and these locks generally have complex and precise structures. But the increased security of these locks comes at the cost of complexity and high cost, and even advanced locks can be cracked by criminals over time. [0004] In recent years, with the rise of the Internet of Things, safes are increasingly using smart electronic locks for remote control and management, in which fixed passwords are tran...

Problems solved by technology

[0006] However, the disadvantage of the electronic lock of the conventional safe is that even if the authentication process of the password is difficult to crack, as time goes by, the static and unchanged password may still be known or cracked by malicious parties through various methods, such as camera or Peeping at the process of users entering their passwords, thus causing losses to users
