Embodiment Construction
[0017] figure 1 is a block diagram illustrating a configuration example of the communication control system according to the embodiment. Such as figure 1 As shown in , the communication control system 1 includes a terminal device 10 , a communication control device 20 and a communication device 30 . Among them, the terminal device 10 and the communication control device 20 are connected to the first communication medium 2 . The communication control device 20 and the communication device 30 are connected to the second communication medium 3 . A plurality of communication devices 30 can be connected to the second communication medium 3 .
[0018] In the above configuration, the terminal device 10 acquires encoded first authentication information, decodes the acquired encoded first authentication information, and transmits the decoded first authentication information to the communication control device 20 . Such a terminal device 10 includes a device for inputting a tag, suc...

It relates to a communication control device, method and system. According to an embodiment, a communication control device includes an acquisition unit, a first authentication unit, an output unit, a second authentication unit, and a connection permission unit. The acquisition unit acquires, during initialization, first authentication information for authenticating the communication device from a terminal device that acquires and decodes the encoded first authentication information via the first communication unit. During initialization, the first authentication unit performs connection authentication of the communication device via the second communication unit based on the acquired first authentication information. When the connection authentication is successful based on the first authentication information, the output unit encrypts second authentication information different from the first authentication information, and outputs the encrypted second authentication information to the communication device. During operation, the second authentication unit performs connection authentication of the communication device via the second communication unit based on the second authentication information. The connection permitting unit permits the connection of the communication device when the connection authentication is successful.
Description
[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Japanese Patent Application No. 2014-059875 filed on March 24, 2014; the entire contents of which are incorporated herein by reference. technical field [0003] The embodiments described herein relate to a communication control device, a communication control method, and a communication control system. Background technique [0004] In a system having a communication device such as a Home Area Network (HAN) device and a communication control device such as a Home Energy Management System (HAMS) server, a technique for performing initialization of the communication control device is known. For example, authentication information (certificate) including a one-time password (OTP) and a public key of a communication device is two-dimensionally coded, and the prepared two-dimensional code is read by an introducer such as a mobile phone. ) to read. Then, the director not...
