Information transmission method, network access method and corresponding terminals

Abstract

The invention mainly aims to provide a mobile terminal and an information transmission method adopted by the mobile terminal. The information transmission method comprises the steps of acquiring information to be transmitted; constructing a data message, wherein the data message is enabled to contain the information to be transmitted and a specific identifier set used for identifying the format of the information to the transmitted so as to restore the information to be transmitted, and the specific identifier set comprises a plurality of formatting identifiers; and sending the data message. In addition, the invention further discloses an intelligent terminal and a network access method adopted by the intelligent terminal correspondingly. According to the invention, an effect of communication security of a fast connection technology realized on the basis of an IEEE 802.11 protocol is further strengthened through improving content representation loaded by the data message by the aid of message control technologies.

Description

Technical field [0001] The invention relates to information security technology, in particular to a mobile phone terminal and an information transmission method adopted by it, as well as an intelligent terminal and a network access method thereof. Background technique [0002] The control technology for the intelligent terminal to access the target network, based on the technology regulated by the IEEE802.11 protocol, has been vigorously developed, and its application is becoming more and more common. Based on AD-Hoc and WiFiDirect technology at the earliest, a direct connection between the control end (transmitting end) and the receiving end was established, and then the configuration information used to access the target network was transmitted, including the service set identification of the target network and login password. The traditional direct connection method is inefficient because it needs to perform a complicated handshake and handover process between the control end...

Problems solved by technology

The reason is that no matter whether the private key encryption based on symmetric encryption technology is used, or the public key encryption based on asymmetric encryption technology is used to encrypt the information to be transmitted, the key for encrypting the information to be transmitted is always fixed. Therefore, illegal Users can intercept the data packets generated during multiple transmissions for brute force cracking, or simulate the data packets of the sending end, launch a DDOS-like attack on the receiving end, paralyze the receiving end, and even cause other adjacent devices including WiFi routers to fail because of the need. Recognizing data frames suffers the same
