Provided is an authentication device capable of generating a master key suited to a UE in a 5GS. The authentication device (10) includes a communication unit (11) configured to, in registration processing of user equipment (UE), acquire UE key derivation function (KDF) capabilities indicating a pseudo random function supported by the UE, a selection unit (12) configured to select a pseudo random function used for generation of a master key related to the UE by use of the UE KDF capabilities, and a key generation unit (13) configured to generate a master key related to the UE by use of the selected pseudo random function.

A method for secure transmission of user-authenticating information is provided. The method includes steps of: a service-providing server (a) determining whether a public key of the user is registered in a blockchain network, and instructing a user-authenticating information generator to generate user-authenticating information for reference, instructing an encrypting engine to encrypt the generated user-authenticating information for reference by using the public key of the user retrieved from the blockchain network, and instructing a message-sending part to transmit the encrypted user-authenticating information for reference to a mobile device of the user; and (b) in case that user-authenticating information for comparison is acquired from the user device and if the user-authenticating information for comparison is determined as identical to the user-authenticating information for reference, providing the user device with the service desired by the user.

A system, method, and computer-readable medium are disclosed for providing a short message tool for identifying and correlating relationships between and among multiple short messages. The short message tool collates the short message data from all company related short messages and generates a report and create a map between the contents, customers and the revenue. Such a multiple short message tool defines a workflow to generate a report from multiple short messages. More specifically, in certain embodiments the customized report may be customized based on based on lines of business (LOBs), number of short messages and re-generation of short messages (referred to as re-tweets when the short messages are Twitter type short messages), favorites, and information about individual users.
