Problems solved by technology

However, NB-IoT cannot obtain the temporary password of the server in real time in PSM mode
When the user operates the terminal, the terminal is woken up and exchanges data with the server. At this time, the delay can be as long as 10 seconds, which seriously affects the password verification experience.
If the current network is unstable, it may even cause verification failure

Embodiment 1

[0049] Such as figure 1 As shown, a method for reducing the time delay in issuing a temporary password of an IoT terminal according to an embodiment of the present invention is provided, which includes the following steps:

[0050] S101 receives a request from a user to obtain a password unlocking through a client. The password is at least one password in the password list. The password list is pre-generated and distributed by the server and stored locally, and includes multiple random passwords corresponding to each time period;

[0051] The combination of the password is composed of one or more of words, letters, numbers and symbols.

[0052] As shown in the following table, set a period of time as 24 hours, from 0:00-24:00, each time period is one hour, from 0:00-24:00 can be divided into 24 time periods, each time period Corresponding to a password, they are password 1 to password 24. However, during operation, since the time when the user applies for the password occurs at the s...

Embodiment 2

[0067] Such as figure 2 As shown, there is provided an apparatus for reducing the time delay of issuing temporary passwords of IoT terminals according to an embodiment of the present invention, including:

[0068] The first receiving module A201 is used to receive a user's request for unlocking a password through the client. The password is at least one password in the password list. The password list is pre-generated and distributed by the server and stored locally, and includes multiple corresponding Random password for each time period;

[0069] Specifically, the first receiving module A201 receives the password list at regular intervals, and then the storage module A206 stores the password list;

[0070] After the storage module A206 stores the password list locally:

[0071] First, a pre-existing local password token guards the password list to prevent password leakage;

[0072] Second, the deletion module A207 deletes the obsolete password in the password list password.

[0073] ...

Embodiment 3

[0079] Such as image 3 As shown, a method for reducing the time delay in issuing a temporary password of an IoT terminal according to an embodiment of the present invention is provided, which includes the following steps:

[0080] S201 generates a password list periodically, the password list includes multiple random passwords corresponding to each time period;

[0081] S202 sends the password list to the above-mentioned device for reducing the time delay of issuing temporary passwords of the Internet of Things terminal.

[0082] Step S202 specifically refers to:

[0083] The password list is sent from time to time to a device for reducing the time delay of issuing temporary passwords for IoT terminals as in the second embodiment.

Abstract

The invention provides a method and a device for reducing the time delay of temporary password transmission of an Internet of things terminal, and a server. The method comprises the following steps: receiving a request of a user to obtain a password through a client, wherein the password is at least one password in a password list, the password list comprises a plurality of random passwords corresponding to each time period respectively, and the time period refers to dividing a period of time into a plurality of time periods; Parsing the request to obtain a time of the request and a corresponding time period; Sending a password corresponding to the time period to the client according to the time period; obtaining the password input to unlock the connection; verifying whether the password input is the password in the corresponding time period, and if yes, unlocking it; otherwise, giving out a prompt for incorrect password entry. The invention distributes the password to the local storage in advance, so the user operation can realize the real-time password input and verification, and is not limited to the time delay brought by the network communication mode.

Description

Technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a method, a device and a server for reducing the time delay of issuing a temporary password of an Internet of Things terminal. Background technique [0002] In the application scenarios of IoT smart locks, it is often necessary to send a one-time or time-sensitive temporary password to the user. After the user sends a request instruction to the server, the server issues a random password to the user's mobile phone and smart terminal. When the user manipulates the smart terminal, the terminal verifies the random password. [0003] In the prior art, 433M high-frequency polling or BLE is often used to construct a communication network to ensure that when a user operates the terminal, a random password has been issued to the smart terminal. [0004] Smart terminals powered by dry batteries require very low standby power consumption. However, communication methods that increa...
