NFC mobile intelligent terminal security access control system and control method thereof

Abstract

The invention discloses an NFC mobile intelligent terminal security access control system and a control method thereof, including an NFC mobile intelligent terminal, an access control controller, a server and an electronic lock. An application program module and an NFC reading module are installed in the NFC mobile intelligent terminal. NFC tag module, door lock driver module and audio module are installed in the access control controller, and a server-side module is installed in the server. The server-side module authenticates the NFC reading module and the NFC tag module, and the NFC tag module also verifies the Perform authentication with the NFC reading module, and when the NFC tag module is authenticated, the door lock driver module drives the electronic lock to open; the present invention hides the identity of the NFC reading module and the NFC tag module during the authentication process, and hashes them , which can prevent eavesdropping and forgery attacks; at the same time, random numbers are added to the interactive information, and shift operations are performed to prevent data replay, data tampering and other attacks.

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...

AI Technical Summary

Problems solved by technology

[0007] The above method mainly has two deficiencies: delay, low security, and poor user experience; for information interaction subjects with limited resources, cryptography improves security while also bringing negative impacts, such as energy consumption high, expensive, etc.

[0014] The disadvantages of this scheme are: the authentication in the scheme is one-way authentication, that is, it is only for NFC mobile phone authentication, which cannot effectively prevent the clone attack of the NFC card reader module and the Arduino module; the data transmission in the scheme is transmitted in plain text, which is vulnerable to Attacks such as eavesdropping and data replay
