NFC (Near Field Communication) mobile intelligent terminal security access control system and control method thereof

Abstract

The invention discloses a NFC (Near Field Communication) mobile intelligent terminal security access control system and a control method thereof. The NFC mobile intelligent terminal security access control system comprises a NFC mobile intelligent terminal, an access controller, a server and an electronic lock, wherein the NFC mobile intelligent terminal is internally provided with an application program module and a NFC reading module; the access controller is internally provided with a NFC labeling module, a door lock driving module and an audio module; the server is internally provided with a server side module; the server side module is used for identifying the NFC reading module and the NFC labeling module, and meanwhile, the NFC labeling module is also used for identifying the server side module and the NFC reading module; the door lock driving module drives the electronic lock to open after the NFC labeling module passes the identification. During an identification process, identity labels of the NFC reading module and the NFC labeling module are hidden, and hash processing is carried out on the identity labels, so that eavesdrop and forgery attacks can be prevented; meanwhile, random numbers are added in interaction information, and shift operation is carried out, so that attacks of data replay, data tampering and the like can be prevented.

Description

technical field [0001] The invention relates to an NFC mobile intelligent terminal security access control system and a control method thereof, belonging to the technical field of NFC access control systems. Background technique [0002] In real life, common access control measures include mechanical locks, IC card access control, fingerprint access control, etc. These access control measures have various problems, such as inconvenient to carry, low security, easy to forge, and expensive. The development of NFC near-field communication technology provides an opportunity to realize a convenient and fast electronic door control measure. The access control system based on NFC mobile smart terminal realizes a method of using mobile smart terminal to open the door control, which is convenient and fast. [0003] However, in practical applications, NFC technology is vulnerable to attacks such as eavesdropping, data tampering, data replay, and cloning, which may cause user privacy d...
