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 includ

Abstract

The invention mainly aims to provide a mobile terminal and an information secure transmission method adopted by the mobile terminal. The information secure transmission method comprises the steps of acquiring information to be transmitted; constructing a data message, wherein the data message is enabled to contain a secondary ciphertext and a secondary key, the secondary ciphertext is formed in a mode that the information to be transmitted is encrypted by a primary key so as to form primary ciphertext and that the primary ciphertext is encrypted by the secondary key containing a random factor so as to form the secondary ciphertext; and sending the data message. Correspondingly, the invention further provides an intelligent terminal and a network access method thereof. 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 message by the aid of password technologies.

Description

technical field [0001] The present invention relates to information security technology, in particular to a mobile terminal and an information security transmission method adopted therefor, and at the same time relates to an intelligent terminal and a network access method thereof. Background technique [0002] The control technology for intelligent terminal access to the target network is based on the technology specified by the IEEE802.11 protocol, and has been vigorously developed, and its application is becoming more and more common. Based on AD-Hoc and WiFiDirect technology, the direct connection relationship between the control terminal (sending terminal) and the receiving terminal is established, and then the configuration information for accessing the target network is transmitted, including the target network’s service set identifier and login password. The traditional direct connection method is inefficient due to the complex handshaking and switching process betw...
