Problems solved by technology

[0007] However, in these existing technologies, it is necessary to have a complex and costly system for issuing and encrypting the authentication key. Furthermore, if the authentication key and password are leaked or cracked, there is a possibility that the secure transmission of data cannot be guaranteed. dangerous

Embodiment Construction

[0030] Hereinafter, the configuration of the present invention will be described based on preferred embodiments with reference to the drawings.

[0031] The present invention is based on the premise of a communication system in which a plurality of communication devices are connected to an IP network through a communication line assigned a unique identification number (IP address), and each of the plurality of communication devices is pre-registered with a unique IP address. Based on the IP addresses of the communication lines of other communication devices that are permitted to communicate, the communication lines are uniquely connected by the three-way handshake based on these registered IP addresses, and data communication is performed between the connected communication devices.

[0032] figure 1 is a sequence diagram based on the data communication method of the present invention.

[0033] refer to figure 1 , according to the data communication method of the present inv...

Abstract

Connect a plurality of communication devices to the IP network through a communication line assigned a unique identification number, register the identification numbers of other communication devices that are allowed to communicate in each communication device, and connect the communication line to the IP network through a three-way handshake based on the identification number. Uniquely connect for data communication. When a connection is established between these communication lines by starting another communication line, the connection is temporarily cut off. Afterwards, in the communication line on the activated side, it is judged whether the signal of response from the communication line on the activation side to the call-back signal sent to the communication line on the activation side arrives at a predetermined timing. , to determine whether a call-back signal is sent from the activated side communication line at a predetermined timing, and data communication is performed only when the legitimacy of the communication lines of both the activation side and the activated side is confirmed.

Description

technical field [0001] The invention relates to a method for data communication in an IP network. Background technique [0002] In recent years, automatic meter reading systems such as gas and water pipes, smart grids, HEMS (Home Energy Management System), remote monitoring systems, sensor systems, etc., have been connected to each other through a communication network to achieve autonomous energy consumption. M2M systems for monitoring, controlling, etc. are spreading. [0003] In such an M2M system, usually, a center-side communication device (one device) and one or more communication terminal devices (the other device) are connected through communication lines each assigned a unique identification number (IP address). Connected to IP network. [0004] Furthermore, the communication line of the center side communication device and the communication line of the communication terminal device are uniquely connected by a so-called three-way handshake based on the IP address,...
