Abstract:
PURPOSE: A portable USB(Universal Serial Bus) storage is provided to increase usability, mobility, convenience by making an USP port put in the inside of an external case without a cap for protecting the USB port. CONSTITUTION: A data storage is embedded into the external case(11). The USB port(12) is slid/installed into the inside of the external case. A controlling tool(13) selectively controls the reception of the USB port. The controlling tool comprises a controlling switch(16) performing the seesaw movement, a stopper(18), and an elastic part(19) restoring the received USB port by installing between the external case and the USB port.
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: An authentication issue request/process apparatus and method in a wireless public key infrastructure, and an authentication issue system using the same are provided to issue an authentication in the wireless public key infrastructure by a message signature function like a wireless markup language script sign text. CONSTITUTION: An authentication issue request device(100) signs an authentication request message using a user' identification, password, a signature public key, and a signature authentication and transmits it to an authentication issue processor(200) through a wireless network. The authentication issue request device(100) includes an initial information input/generation and providing module(110), an authentication request message generating module(120), an authentication request message signature module(130), and an authentication request control module(140). The authentication issue processor(200) tests and processes the signed authentication request message of the authentication issue request device(100). The authentication issue processor(200) includes an authentication request message signature testing module(210) and an authentication request message process module(220).
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). A reference number and living body information of the corresponding user are extracted for a user authentication(S502). 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).
