Client and server for encrypting transmission data, network system and method

Abstract

The invention discloses a client. The client is resided in a network system; the network system further comprises a server; the client comprises a network adapter, a storage module, a first message processing module, and a second message processing module, wherein the storage module is applied to storing a key; the first message processing module is applied to generating a first network message; the second message processing module is applied to generating a second network message based on the first network message and sending to the server via the network adapter, and is further applied to receiving a response message by the network adapter; the first message processing module is further applied to generating a fourth network message, the fourth network message including original data encrypted using a communication parameter; the second message processing module is further applied to encrypting the original data using the key, so as to obtain encrypted data, generating a fifth network message based on the fourth network message and the encrypted data and sending to the server via the network adapter, the fifth network message including the encrypted data. The invention further discloses the corresponding server, network system and method.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a client, a server, a network system and a method for encrypting and transmitting data. Background technique [0002] With the rapid development of network communication technology, the continuous deepening of Internet applications, and the increasingly rich information carried, the Internet has become an important infrastructure of human society. Among them, the security of data transmission on the network has also attracted widespread attention. [0003] Existing encrypted communication technology, such as the encrypted communication technology based on the HTTPS protocol, before encrypted transmission, the communication parties need to first negotiate the encryption algorithm, verify the identity, etc., these operations are plain text, easy to be recognized by the outside. Therefore, criminals can easily identify the traffic as encrypted traffic through the encrypti...

AI Technical Summary

Problems solved by technology

Therefore, criminals can easily identify the traffic as encrypted traffic through the encryption characteristics of these plaintexts, so as to conduct targeted deciphering

In this regard, the traditional way of dealing with it is to try to eliminate encryption features to avoid being identified, but the actual effect is not good
