Access control system and control method thereof

Abstract

The invention provides an access control system and a control method thereof. The access control system comprises a server, a mobile terminal and an access control device. Multiple encryption is carried out in a secret key or two-dimensional code transmission link, so that the secret key is prevented from being eavesdropped or tampered; propagation and tampering of the two-dimensional code are prevented; security of transmissions is enhanced, and eavesdropping or tampering in a verification information transmission process is prevented; the door opening permission of the user is verified according to the time difference of application time, the secret key, the UUID of the access control device and the user permission information; the security is improved, the character string analysis iscarried out in the server, the generation algorithm of the character string is prevented from being acquired by a third party at a mobile phone terminal, and the secret key is carried out in ae generation algorithm and an encryption algorithm in the server, so that the security is improved.

Description

technical field [0001] The invention relates to the technical field of access control, in particular to an access control system and a control method thereof. Background technique [0002] The access control system has been widely used in various security fields such as office buildings, residential areas, unit doors, and door control. The current main authorization forms of the access control system are: swiping IC cards, fingerprints, passwords and mobile phone authorization. , passwords or swiping mobile phones to determine access control authority, while swiping mobile phones currently mainly rely on QR codes for verification. Since QR codes are easy to copy in the form of images, QR codes can be disseminated in various ways , low security, two-dimensional codes are also called two-dimensional barcodes, usually QR Code is used as the coding rule, and the open coding rules are conducive to standardizing the two-dimensional code market, and also lower the threshold for mod...
