METHOD AND SYSTEM FOR SECURELY ACCESSING PORTABLE HOTSPOT OF SMART PHONES

摘要

A method and system for accessing a portable secure hotspot of smart phones. The system comprises a smart phone used as a wireless access point and a smart phone used as an access terminal, wherein the wireless access point comprises a wireless access point NFC module and a first data transmission module; the access terminal comprises an access terminal NFC module and a second data transmission module; andthe wireless access point is connected to the access terminal by the NFC modules to conduct WPA security authentication, and conduct data encryption transmission by means of the first data transmission module and the second data transmission module. In the method and system of the present invention, the security authentication process is completed in an NFC manner between the wireless access point and the access terminal without using the ordinary wireless local area network authentication mode. Because the communication distance of NFC is within 10 cm, more reliable communication between the two is ensured by a short range so that an attacker has no opportunity to acquire a handshake packet. After authentication is completed at a short range, longer-range communication can also be performed by means of WPA encryption data transmission.
