RADIO COMMUNICATION SYSTEM, AND, AUTHENTICATION METHOD

摘要

PROBLEM TO BE SOLVED: To authenticate devices connected to a radio terminal at a side of a wireless network, and also to perform the authentication through simple procedures even when the relevant devices are replaced. SOLUTION: A TE 1 transmits to a radio terminal 2 connected thereto TE authentication data based on its own private information and transmission data addressed to a sensor data server 6. The radio terminal 2 produces authentication data from the TE authentication data and its own private information and transmits to an authentication server 4 a radio terminal authentication request to which the produced authentication data are set. The authentication server performs authentication using the authentication data acquired from the received radio terminal authentication request and private information, held in a storage means that the authentication server itself includes, private information for authentication of the TE1 and private information for authentication of the radio terminal 2 and redirects an authentication results. When the authentication results indicate an authentication success, the radio terminal 2 transmits transmission data received from the TE1 to the sensor data server 6 via a radio base station 3.
