Abstract: PURPOSE: A method for generating a certification path using a verification server on the PKI(Public Key Infrastructure) is provided to reduce client's load by making the verification server process a certification path generating work instead of the client, and effectively perform the certification path generation by previously generating/storing the certification path and reusing the certification path. CONSTITUTION: The verification server connecting to the client collects a certificate from a linkable certification organization, and generates/stores the certification path realized by the certificate. When the client requests certification by providing the certificate to the verification server(321), the verification server checks that the certification path for the certificate is stored(322). In case that the certification path is existed(323), the verification server verifies the certificate by using the existed certification path, and transmits a verification result to the client.

Abstract: PURPOSE: A method for issuing a certificate using living body information in a public key infrastructure authenticating system is provided to directly issue a certificate without inputting a complex approval code and improve a security of a certificate issuing procedure. CONSTITUTION: A certificate issuing request message is received from a user system, which connects to an authentication system through the Internet(S500).

It is checked whether the transmitted living body information of the user is identified with living body information of a member registration user corresponded to a reference number registered and stored in a database storage(S504). If the living body information is identified with the registered living body information, an approval code of the user is created and supplied to the user system(S510). A public key created from the user system is received(S516) and a certificate is issued(S524).

Abstract: The present invention relates to a tag key distribution technology in a RFID system and the feature of a RFID is to receive changed key information from a tag key information server by requesting changed version information after an update version of the key information by communicating with the tag key information server in order to effectively distribute a tag key to a reader by the tag key information server having information for a RFID tag key. According to the present invention, the tag key information server remarkably reduces network loads compared to a method which always transmits the whole tag key at the predetermined time point and minimizes the time when the reader did not respond during tag key transmission by managing the tag key by version and transmitting it to each reader.
