Embodiment Construction

[0038] Next, the best mode for carrying out the present invention will be described. In this embodiment, when devices equipped with short-range wireless communication technologies such as Bluetooth (registered trademark) and wireless LAN are connected to each other by short-range wireless communication, information related to security such as an authentication key and a secret key is converted into a barcode, and By exchanging information through this barcode (visible symbol), object authentication is performed, and at the same time, the encryption key used in the future short-range wireless communication is transmitted as confidential information.

[0039] Next, start the side machine for the program ( figure 1 10) and the response side machine ( figure 1 30) The case where a short-range wireless communication connection is performed will be described. First, the program starts the side machine ( figure 1 10) Use the authentication key generation part (key generator; figu...

Abstract

To easily and simply perform authentication and delivery of secret information between devices which perform a short-range wireless communication. When a device including a short-range wireless communication unit (20), a barcode creating unit(16), a barcode reading unit (17), and a barcode analyzing unit (18) is connected to a device including a short-range wireless communication unit (40), a barcode creating unit (36), a barcode reading unit (37), and a barcode analyzing unit (38) for performing the short-range wireless communication, interaction is performed in such a manner that security information such as an authentication key and an encryption key is converted into a barcode, for recognition by other party. Authentication of the other party is performed through the interaction usingthis barcode, and the encryption key to be used for the subsequent short-range wireless communication is also delivered.

Description

technical field [0001] The present invention relates to an authentication method between close terminals, a distribution method of concealed information, a device, a system, and a program, and particularly relates to a characteristic technology in a communication path / communication method for authentication and distribution of concealed information. Background technique [0002] Near-field communication technologies such as Bluetooth (registered trademark), UWB (Ultra Wideband Wireless), and wireless LAN (Local Area Network: Local Area Network) are rapidly spreading. In recent years, in mobile phones and PDAs (Personal Digital Assistants: Personal Digital Assistants), communication functions using these technologies have been widely used. By connecting devices equipped with these short-range wireless communication technologies, and implementing dial-up connections, facsimile connections, and personal ad hoc connections, various data communications can be implemented wireless...
