Smartphone portable point safe access system and method

Abstract

The invention discloses a smartphone portable point safe access system and a smartphone portable point safe access method. The system comprises a smartphone as a wireless access point and a smartphone as an access terminal, wherein the wireless access point comprises a wireless access point near field communication (NFC) module and a first data transmission module; the access terminal comprises an access terminal NFC module and a second data transmission module; the wireless access point is connected with the access terminal by the NFC modules so as to conduct Wi-Fi protected access (WPA) safety authentication, and execute data encryption transmission by using the first data transmission module and the second data transmission module. According to the method and the system, the safety authentication process between the wireless access point and the access terminal is finished by using the NFC mode, without using the general wireless local area network authentication mode, due to that fact that the communication distance of NFC is within 10cm, the communication between both is ensured to be more reliable by adopting the close range, so that an attacker has no opportunity to obtain a handshake authentication package; after the authentication is finished within the close range, the communication in longer range can also be executed by using the WPA encryption transmission data.

Description

technical field [0001] The invention relates to a mobile communication terminal, in particular to a method and system for securely accessing a portable hotspot of a smart phone. Background technique [0002] With the development of the mobile Internet, various mobile communication devices can now access the Internet by connecting to a hotspot AP (Access Point, wireless access point) through WIFI (Wireless-Fidelity, wireless fidelity). As one of many AP hotspots, the AP in the smart phone can also provide WIFI access functions for various mobile communication devices anytime and anywhere. Due to the openness of WIFI, communication security in accessing the AP through WIFI and then connecting to the Internet has become the focus of Internet security. [0003] At present, WIFI hotspot devices support security protocols for wireless LAN transmission, that is, the security authentication methods between the wireless access point AP and the access terminal STA (Station) include W...

Problems solved by technology

However, the WEP encryption method has the possibility of being intercepted by a third party, and the signal password is easily cracked, so the security is not high.

At present, the vast majority of WIFI hotspot devices use WPA / WPA2 encryption to connect, which is much safer than WEP encryption, but there are still certain security risks and the possibility of being cracked
