Abstract:

Taking advantage of Near Field Communication(NFC) technology’s features of exchanging data safe, convenient, lower power consumption, two programs which using NFC to establish connection for WiFi transmission are proposed: passing WiFi LAN password and AES key by NFC touch. The combination of NFC and WiFi transmission can avoid searching the device as WiFi hotspot, taking part in Wireless Local Area Network(WLAN) through complex authentication and other complex operations in the traditional WiFi transmission process while ensuring the security of data transmission, solving complex of connection process, power consumption and other issues. According to one of the two programs, the ‘NFC+WiFi’ data transmission system is designed and implemented with a good test performance, the speed of establishing connection significantly superior to the traditional WiFi transmission. Test results show that using the program for data transmission between mobile devices will be with high availability.
