Embodiment Construction

[0019] Such as figure 1 As shown, a wireless network-based data security transmission method of the present invention mainly includes a database, a device end and a system end;

[0020] The database has data storage and retrieval functions, and is responsible for saving the device identification information of each device;

[0021] The device end has a wireless network communication function, and is responsible for securely transmitting user data to the system end through the wireless network, and is also responsible for parsing and processing encrypted data from the system end;

[0022] The system end is connected to the database, has network communication functions, and is responsible for providing an interface for users to register device identification, etc., and is responsible for parsing and processing encrypted data from the device end, and securely transmitting the system end data that needs to be delivered to the corresponding device side.

[0023] Specifically in...

Abstract

The invention discloses a method for safely transmitting data based on a wireless network. A pair of key factors and a group of key sets are respectively arranged at a system end and an equipment end; during communication of the system end and the equipment end, a sender calculates a check sum of the data to be sent, calculates an authentication identifier (ID) by using the key factors and an equipment identifier, randomly selects a key from the key sets to encrypt the data to be sent, and sends the encrypted data and an adopted key code; and after receiving the data, the receiver acquires the corresponding key from the key sets through the key code, decrypts the data, calculates the authentication ID by using the equipment identifier and the key factors, judges whether the authentication ID accords with the authentication ID which is sent, and judges whether the check sum is accurate if the authentication ID accords with the authentication ID which is sent, so that the data can be safely transmitted. The method has the advantages that: the equipment identifier is fully utilized; functions of dynamic identity identification, data check and transmission encryption are integrated; safety communication of the data can be guaranteed; and presetting of an unrepeatable master key in each piece of equipment is not required.

Description

technical field [0001] The invention relates to a wireless network-based data security transmission method, in particular to data transmission between a wireless network communication device end and a system end. Background technique [0002] Establishing an effective wireless network data transmission system is a key technology in wireless network data security transmission, and it is also an effective means to solve enterprise mobile applications such as: fast moving consumer goods industry business personnel management mobile CRM system, sensitive business data security transmission. [0003] At present, the secure transmission of wireless network data generally pre-sets a non-repeatable master key to each device end, and then uses the master key to perform identity authorization on the system end and the device end, and then uses the master key combined with random numbers to generate a session key , and use the master key to encrypt and decrypt the session key and autho...
