Data transmission method, server side and client

Abstract

The invention discloses a data transmission method, a server side and a client. The data transmission method comprises the following steps that: the server side and the client carry out information interaction through an authentication protocol, and perform identity authentication with each other; a session key is generated by the server side and the client through a key exchange protocol; a data packet to be transmitted is encrypted by the client through adopting an encryption algorithm and the session key, and the encrypted data packet is transmitted to the server side; and the received encrypted data packet is decrypted by the server side through utilizing the session key and the encryption algorithm, and the corresponding operation is executed. According to the scheme, unidirectional transmission of the transmitted data packet from the client to the server side can be implemented, establishing process is simple, and the computing resource is effectively saved, so that the data transmission is safer and more reliable.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a data transmission method, a server and a client. Background technique [0002] The network pipeline operation is a one-way data transmission method based on the network, which can transmit the data obtained from the standard input of the client to the server, and output it to the standard output from the server. If it is used with a pipeline, the standard output of the upstream program can be transmitted to the standard input of the downstream program under the remote host, which is similar to the networking of the pipeline mechanism in the POSIX system, so it is called a network pipeline. [0003] In the prior art, to realize the network pipeline operation between different clients and service ends, the following two methods can usually be adopted: one is to adopt virtual private network (Virtual Private Network, VPN) or SSH (Secure Shell, safe Shell protoco...

Problems solved by technology

[0004] However, the above two methods either need to build and maintain an uninterruptible secure channel because the transmitted data is not encrypted, and there is a problem of wasting computing resources; or they need to rely on RPC (Remote Procedure Call Protocol (Remote Procedure Call Protocol) service, but there is a problem of poor security; or it does not conform to the business process, which leads to the problem of easy misoperation, and the above two methods do not support the relationship between multi-client and single server. Concurrently transfer data between
