Problems solved by technology

When different users use the password to perform operations on the same electronic device, because the password is the same, the background cannot distinguish the user of the password, which in turn affects the management and control of the password user
For example, for a room door lock, within a certain period of time, the door lock passwords obtained by different users are the same, so the background will not be able to distinguish who performed the door opening operation

Embodiment 1

[0045] figure 1 It is a flow chart of a password generation method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of generating a password. The method can be executed by a password generation device, which can be implemented by software and / or hardware , and integrated in the password production end, wherein the password production end can be determined according to the actual application scenario, for example, in the door lock industry, the password production end can be a server, and in the bank, the password production end can be a USB shield. Specifically, refer to figure 1 , the method includes the following steps:

[0046] S110. Obtain a preset shared key and a valid time of the password input by the user.

[0047] The shared key is a key shared by the password producer and the password verification end. The form and content of the shared key can be set according to requirements, and the embodiment does not limit it. ...

Embodiment 2

[0068] image 3 It is a flow chart of a password verification method provided by Embodiment 2 of the present invention. This embodiment is applicable to the case of verifying passwords. The method can be executed by a password verification device, which can be implemented by software and / or hardware and integrated in the password verification terminal, wherein the password verified by the password verification terminal is generated by the password production terminal described in the above embodiment, and the password verification terminal matches the password production terminal, for example, when it is applied to a door lock In the industry, when the password production end is a server, the password verification end can be a door lock. When it is applied to a bank, when the password production end is a USB shield, the password verification end can be a server. It should be noted that there is no communication between the password producing end and the password verifying end....

Embodiment 3

[0087] Figure 5It is a structural diagram of a password generation device provided by Embodiment 3 of the present invention. The device can execute the password generation method described in Embodiment 1 above. Specifically, the device includes:

[0088] An information acquisition module 310, configured to acquire the preset shared key and the effective time of the password input by the user;

[0089] The user password generating module 320 is configured to generate a user password corresponding to the user according to the shared key and password effective time, combined with a random number of a set length, and send the user password to the user terminal of the user , so that the user can obtain the user password.

[0090] Embodiment 3 of the present invention provides a password generation device, which generates a corresponding the user password of the user, and send the user password to the user terminal of the user, so that the user obtains the user password. Compar...

Abstract

The embodiment of the invention discloses a password generation method, a verification method, a corresponding device, a corresponding system and a storage medium. The password generation method comprises the following steps: acquiring a preset shared key and password effective time input by a user, generating a user password corresponding to the user by combining a random number with a set lengthaccording to the shared key and the password effective time, and sending the user password to a user side of the user, so that the user acquires the user password. Compared with the prior art, the embodiment of the invention introduces the random number in the process of generating the user password, so that the generated user password is different even if the effective time of the password is the same, the user password obtained by different users at the same time is prevented from being repeated, and the user password is more controllable.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of information security, and in particular, to a password generation method, a verification method, a corresponding device, a system, and a storage medium. Background technique [0002] The Time-based One-time Password (TOTP) algorithm is an algorithm for computing a one-time password from a shared secret key and the current time. The core goal of this algorithm is that within a certain period of time, the password generated by one end alone can be verified and passed by the opposite end. [0003] In the prior art, the TOTP passwords generated based on the TOTP algorithm are the same within a certain time range, that is, the passwords obtained by different users within the time range are the same. When different users use the password to perform operations on the same electronic device, because the passwords are the same, the background cannot distinguish the users of the passwords...
