摘要
利用近场通信(NFC)技术安全性高、便捷和功耗低的特点,提出采用NFC为无线保真(WiFi)传输建立连接的2种方案:NFC触碰传递WiFi局域网的密码和NFC触碰传递上层加密传输的密钥,避免传统WiFi传输通过搜索热点后需经过认证加入局域网的繁琐操作,同时保证数据传输安全性。根据第2种方案实现NFC+WiFi数据传输系统,测试结果表明,该方案的建立设备连接速度和传输速度均快于传统WiFi方式。
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.
