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.

Abstract: Updating a subscriber identity module, SIM, on a host device by deriving a pre-shared key by requesting a SIM identifier via communication module of the host device; receiving SIM identifier and deriving an agent identifier from SIM identifier; transmitting agent and SIM identifiers to SIM update server; receiving a random value from SIM update server and supplying it to the SIM to initiate SIM authentication procedure. In reply, receiving an authentication response from the SIM; and deriving pre-shared key from authentication response; transmitting an update request message to SIM update server, wherein the update request message comprises the agent identifier and is encrypted before transmission using the pre-shared key; receiving an update response message from the SIM update server which has update data and is encrypted using pre-shared key; and following decryption of update response message using derived pre-shared key, transmitting update data to communication module.
