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

Embodiment Construction

[0128] In the prior art, the use of pipelines to establish data transmission between the client and the server usually adopts the following two methods:

[0129] One is the combination of VPN (Virtual Private Network, virtual private network) or SSH (Secure Shell, secure shell protocol) and TCP-PIPE, that is: first, set up a VPN between the client and the server or use SSH Proxy to build a secure channel, and then register the TCP-PIPE server on RPC. Finally, use the TCP-PIPE client and TCP-PIPE server for data transmission.

[0130] On the one hand, since data is transmitted in clear text between the TCP-PIPE client and the TCP-PIPE server, it is necessary to build an additional long-term secure channel to ensure the security of the transmitted data, so there will be waste resource. On the other hand, since the TCP-PIPE server needs to rely on the RPC service for data transmission, and the RPC service itself is not highly secure, it also increases the risk of client and ser...

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...
