Abstract

The invention provides a data transmission method under a public wifi environment. The method comprises the steps that a mobile terminal intercepts a request data packet sent by an application program, the connection of the mobile terminal and a security server is obtained, and the request data packet is encrypted and sent to the security server through the connection; a received data packet is decrypted and restored by the security server to obtain the request data packet, and the request data packet is forwarded to an application server corresponding to the security server; the security server receives a response data packet returned by the application server, the connection of the security server and the mobile terminal corresponding to the response data packet is obtained, and the response data packet is encrypted and returned to the mobile terminal through the connection; the received data packet is decrypted by the mobile terminal to obtain the response data packet, and the response data packet is distributed to the corresponding application program. The data transmission method under the public wifi environment can improve security.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a data transmission method and system in a public wifi environment. Background technique [0002] Existing shopping malls, hotels, amusement parks and other public places are usually equipped with wireless access points in order to facilitate users in the places to access the Internet conveniently. Users can use mobile terminals to connect to the wireless access points through wifi, so as to enjoy the Internet . [0003] However, when the wireless access point of public wifi acts as a gateway to forward the data received and sent by the mobile terminal, there are security risks. Lawbreakers can set up free public wifi privately to lure users to connect with it, and when acting as a gateway to forward data packets transmitted between users and other terminals in the Internet, they can intercept data packets, steal or tamper with the contents of data packets, or Viruses ...
