In order to improve the security and management intelligence of the university open laboratory

based on the combination of Internet of things technology and chaotic encryption technology

the intelligent laboratory system is proposed The system includes ZigBee network control subsystem

gateway

video surveillance

server cloud platform

mobile phone and PC client We use IC (Integrated Circuit) card or NFC (Near Field Communication) combined with RFID (Radio Frequency Identification) and ZigBee technology to control laboratory entrance guard

power supply equipment and lighting All control information is sent to the server via the gateway and synchronized to the cloud platform; the webcam gets the monitoring information and transmits it to the server; mobile phones and PC clients can remotely access all the information on the server and control all network devices in the lab When mobile phones communicate with ZigBee networks

chaos is used to encrypt and decrypt transmission information

the key is obtained by the two hyperchaotic system discretization and scrambling combined multi wheel XOR is used for encryption and decryption Experimental tests show that the system can realize the laboratory 24 hours unattended open management and has improved significantly in security and remote intelligence management
