Abstract: A mobile OTP system providing system is provided, in that it performs security token and OTP management functions, it generates an OTP having high security level in hardware by using a mobile OTP device for performing a security data storage function of encoding and decoding data during data storage, and it generates OTPs necessary for a plurality of services by using one mobile OTP device, thereby safely and easily utilizing it by means of the user.

Abstract: Provided are a security key device for a cloud service, and a system and a method for providing a secure cloud service. The security key device includes: an interface unit detachably connected to a user terminal, and providing an interface with the user terminal; a storage unit storing an encoded user file; and an encoding/decoding transformation supporting controller that, when receiving from the user terminal a file to upload to a cloud server, encodes the file, stores the encoded file in the storage unit, and then transmits the encoded file to the user terminal, and when receiving from the user terminal an encoded file downloaded from the cloud server, stores the encoded file in the storage unit, decodes the encoded file, and transmits the decoded file to the user terminal.

Abstract: A security certification and storage combined apparatus provides a wireless communication function in that it can provide a function of a security certification and a function of a storage device through a general terminal having an USB communication function and a mobile device, which is not equipped with an USB port, and it can exchange data with the mobile device or change the data received from the mobile device through a wireless communication module, thereby easily implementing the certificate verification interface.

Abstract: The present invention relates to a method of searching a metadata server that searches ubiquitous sensor network (USN) metadata servers in a distributed environment. The present invention stores location information on the metadata servers by using a location-server cluster and searches a location of a metadata server in which a specified resource metadata is stored, during a metadata searching request by a client. Accordingly, the present invention can provide a simple and consistent interface to the client using the metadata management servers in terms of the metadata servers and can improve the clarity of service development and can reduce the entire development costs and the maintenance and repair costs.

Abstract: Provided are a telematics transport gateway and an operating method thereof. The telematics transport gateway, includes: a message transporting/receiving unit for receiving service request messages, transmitting the service request messages to a service providing server, receiving a service response message and transporting the service response message to the telematics terminal; a message processing unit for analyzing whether a format of the service request messages is Short Message Service (SMS), Transmission Control Protocol (TCP), or Hypertext Transfer Protocol (HTTP); a controlling unit for extracting user information from the service request message, transmitting the user information to an authentication managing unit and a charging unit, and maintaining a session with the telematics terminal; the authentication managing unit for performing authentication and transporting an authentication result to the controlling unit; and the charging unit for charging for the service.
