Abstract:

The access control system that is used frequently at present is difficult to manage and is easy to be copied. To solve these problems, this paper proposes a smart phone access control system scheme based on QR code hybrid encryption technology, which has better security, and is more convenient to use and manage. The scheme has the following characteristics: 1) The scheme uses QR code of the registered user as the identification, and uses unique sequence number of mobile phone and regularly converted key as the source of QR code. 2) The user registration process is implemented in form of encryption. One-time code based on user event driven and hybrid encryption technologies ensure the timeliness and security of the QR code. 3) QR code generated on mobile phone is scanned by camera, and the door is opened after verifying the user identity. 4) The scheme conects the visitor with the owner. Owners autonomously manage visitors in and out, which reduces the difficulty of management at the same time to ensure the security.
