Embodiment Construction

[0019] Such as figure 1 As shown, the intelligent access control system of the present invention is composed of an access control terminal, a mobile APP and a background server. Each access control terminal is set with a unique identification code, and the mobile phone APP is used as a client to access the background server. The access control terminal can adjust the time through the Bluetooth door opening function of the mobile phone APP to ensure that it is consistent with the time of the background server.

[0020] The inventive method comprises the following steps:

[0021] 1) Assign a unique identification code, ie ID number, to each access control terminal;

[0022] 2) Set a time window for a single access control terminal, and define the start time of the time window as ST; assuming ST is 20, within one hour, 0 minutes, 20 minutes, 40 minutes and 60 minutes are all defined as ST;

[0023] 3) Set a unified encrypted private key PK, and form a set of encrypted sequences...

Abstract

The invention discloses a non-networking dynamic password generation method used for an intelligent access control system. According to the invention, an unique identification code is distributed to each gate inhibition terminal; a window is partitioned for time, the initial time for time window is defined as ST; a group of encryption sequences are composed of PK, ID and ST; a Hash algorithm F is defined, the PK, ID and ST sequences are hashed to six passwords KEY with fixed length; a back-end server sends the dynamic password obtained by calculation to a cell phone APP, the user of the cell phone APP sends the password to a guest through a short message mode; after the dynamic password is input to the gate inhibition terminal, the dynamic password input by the gate inhibition terminal is compared with the generated own password, door opening is consistent, and error reporting is inconsistent. Through low cost, non-networking guest authorizing door opening is realized; the dynamic password is conveniently forwarded, the cell phone is not required for showing to open the door, compared with the guest authorization modes such as two-dimensional barcodes, the usage is more convenient.

Description

technical field [0001] The invention belongs to the field of intelligent access control, and more precisely relates to a non-network dynamic password generation method for intelligent access control. Background technique [0002] With the improvement of the material level, especially the development of smart phones and smart devices, smart products and smart communities are becoming more and more popular. People have put forward higher requirements for the intelligence of the working and living environment. As the core equipment for entering and exiting communities and offices, intelligent access control has also developed rapidly. Most of the traditional access control systems use cards to enter and exit. This method facilitates access control management to a certain extent, but problems such as forgotten or damaged access control cards bring difficulties to management, and visitor authorization cannot be achieved by swiping cards to open the door, which is not convenient e...
