The present invention relates to a server for authenticating a smart chip which is connected to a terminal transmitting and receiving data to and from a smart chip through a network. The server for authenticating a smart chip includes a server transceiver unit receiving a card identifier identifying a user from the terminal; and an authenticating unit generating an authentication key from the card identifier and authenticating the smart chip from the authentication key. The terminal generates a coded message from the card identifier, and the smart chip generates a decoded message from a secret key by receiving the coded message. The card identifier is a public key corresponding to the secrete key. Therefore, the present invention provides safety for a deal by confirming whether a user retains a medium in online/offline dealing. |
