Problems solved by technology

If the load on the server is heavy at this time, the terminal will congest the data channel when the terminal initiates a verification request to the server, which may cause the server to be paralyzed
In addition, since the verification is initiated by the terminal and the verification is passive by the server, no matter what kind of data is sent by the terminal, the server may verify it
In other words, even if an illegal terminal sends data irrelevant to verification to the server, the server may also verify the irrelevant data, which causes a waste of server resources and reduces security

Embodiment Construction

[0018] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and not to limit the present invention.

[0019] figure 1 It shows a schematic structural diagram of a system for connection control between a server and a terminal according to an embodiment of the present invention. Such as figure 1 As shown, the system may include: a terminal 10 and a server 20 connected to the terminal 10. A TCP / IP connection can be established between the terminal 10 and the server 20. After the connection is established, a verification process can be carried out between the terminal 10 and the server 20 to determine whether the other party is a legitimate peer, so as to maintain or disconnect the connection. The verification process provided by the present invention will be described in det...

Abstract

The invention discloses a server for terminal connection control and a server execution method, a terminal for connection control with the server and a terminal execution method, and a system for connection control between the server and the terminal. The server comprises a reception unit for receiving data and sending unit for sending data. The server further comprises a message generation unit for generating an encrypted verification message which is actively sent to a terminal connected with the server through the sending unit, and a control unit which receives decryption data from the terminal through the reception unit verifies the received decryption data, and retains connection with the terminal when the decryption data passes the verification. The connection between the two can be controlled by reverse verification between the terminal and the server, thereby preventing the defects of server overload and resource waste and improving security.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a server for terminal connection control and a method executed by the server, a terminal for connection control with the server and a method executed by the terminal, and a server and terminal The connection between the control system. Background technique [0002] In the communications field, terminal devices usually need to establish a connection with a server to perform corresponding applications. In order to ensure the security of communication, under normal circumstances, after the terminal establishes a TCP / IP connection with the server through the network, authentication between the terminal and the server is required to determine whether the other party is a legitimate peer. [0003] The existing verification method is that the terminal actively initiates a verification request to the server, and the verification request includes verification information. After the se...
