  • Patent number: 11943213
    Abstract: Facilitate configuration of authentication information for a service provided over IP network when there is no shared authentication information between IoT device and service provider device for a service used by IoT device, an intermediary device capable of authenticating legitimate access mediates between devices. An example: a cipher key CK stored in intermediary device and IoT device, as a result of SIM authentication of the SIM of the IoT device, is used as master key for services used by IoT device. By generating unique application key for a service used by IoT device on the intermediary device and IoT device on the basis of master key, and sending it to service provider apparatus from intermediary device by secure connection, common keys are set as authentication information to IoT device and service provider apparatus. A SIM authentication process for generating cipher key can suppress SQN attack based on a bad request.

  • Patent number: 11792206
    Abstract: A connection management apparatus of a relay system specifies, when terminal identification information for identifying a target terminal is acquired from a client terminal, a first relay apparatus that relays communication, and specifies connecting information for the client terminal to connect to the first relay apparatus. The connection management apparatus stores the specified connecting information and the terminal identification information in a storage in association with each other, and notifies the client terminal of the specified connecting information. When the specified first relay apparatus receives access based on the connecting information from the client terminal, the specified first relay apparatus relays the communication between the client terminal and the target terminal on the basis of the terminal identification information associated with the connecting information.

  • Patent number: 11184753
    Abstract: An apparatus for transmitting and receiving data to/from an IoT device to accelerate the spread of IoT. The IoT device 110 generates a message to be transmitted, and transmits, via SMS, the message to the phone number of a first server 101, which is stored in the IoT device 110. The first server 101 notifies the IoT terminal 110, as needed, of having received SMS data including the message, and thereafter delivers the SMS data to a second server 102. The second server 102 specifies a destination with reference to associations between destination identifiers includable in the SMS data and destinations. The second server 102 transmits, to a third external server 123, a portion obtained by excluding the destination identifier from the message or the whole message including the destination identifier.

  • Patent number: 10820191
    Abstract: We describe a system for activating SI Ms, where the system comprises more SI Ms than will be authorised for use on a mobile network. The system comprises a plurality of SIMs, each of the SIMs being configured to provide a first SIM identifier. The first SIM identifiers are reused amongst said plurality of SIMs such that one of the SIMs may provide the same SIM identifier as another of the SIMs. The system includes a SIM authorisation server configured to receive the first SIM identifier from a SIM requesting activation and, in response, to provide a new SIM identifier. The new SIM identifier enables the SIM requesting activation to communicate traffic over the mobile network.

  • Patent number: 9998913
    Abstract: In a management method and a management server for using a plurality of SIM cards, a large number of users can start use easily. First, an MVNO 230A that has obtained one or more SIM cards logs in to a management screen provided by an MVNE 210 in association with a user ID of the MVNO 230A. From the standpoint of the MVNE 210, it is determined whether a user ID of a user who has accessed a management screen of a management server of the MVNE 210 is under MVNO contract (S301). When the user ID is under MVNO contract, an identification number given to each SIM card and a passcode for authentication given as needed are received as registration information (S302).
