Abstract:
A method for differentiated security control for a smart communication terminal based on security policy negotiation includes the steps of: performing mutual authentication between the smart communication terminal and a terminal security control server when the smart communication terminal moves to an autonomous domain; negotiating a security policy between the smart communication terminal and the terminal security control server in the mutual authentication; controlling the resource of the smart communication terminal; monitoring the smart communication terminal to check the operation according to the command of the terminal security control server; and indirectly controlling the smart communication terminal when the smart communication terminal violates the negotiated security policy.
Abstract:
PURPOSE: A method for verifying key validity and a sever for performing the same are provided to reduce necessary operation times for verifying key validity in a signature process or a signature verification process by providing various services based on anonymous authentication. CONSTITUTION: An anonymous authentication server(110) revokes an anonymous secret key owned currently(S810). The anonymous authentication server is opened by generating a revocation list(S820). A service providing server(120) generates a LRL(Local Revocation List) by using a revocation list and its own LL secret key(S830). The service providing server calculates a virtual index of a service user through the signature of a service user(S840). The service providing server verifies the validity of a key of the service user based on the presence of the virtual index included in the local revocation list(S850).
Abstract:
PURPOSE: A system and a method for managing client information and a client terminal and an apparatus for managing the client information are provided to manage corresponding information by using an authentication element and an encryption key. CONSTITUTION: A system for managing client information comprises a client terminal group(100), a network(200), a client information management apparatus(300). The client terminal group requests subscription and authentication by using an authentication element and an encryption key. The network connects the client terminal group with the client information management apparatus. The network includes a broadband communication network and a local area network, etc. The client information management apparatus manages client information in an encrypted type.
Abstract:
PURPOSE: A content management method, system, and rights object management apparatus are provided to prohibit illegal usage for content by enabling a user who has rights for releasing rights object to use content through a mobile storage apparatus. CONSTITUTION: A content playback apparatus receives content from a content service providing apparatus(S504). A rights object management apparatus receives binding rights objects from a content service providing apparatus(S506). When the content playback apparatus requests the rights objects of the content to the rights object management apparatus, the right object management apparatus release the binding of the binding rights objects. The released binding rights objects are loaded on the content playback apparatus(S514).
Abstract:
PURPOSE: A content protection device and a method thereof through combination between additional information and encoding key are provided to prevent decoding of additional information by changing an encoded key when changing additional information. CONSTITUTION: An encoding unit(150) generates an encoding key for encoding requested data and generates encoded data. An additional information managing unit(170) manages additional information including right information about the encoded data. A white box password processing unit(160) generates a white box password table for combining the encoded key and the additional information. A combined data generating unit(180) generates combined data for combining additional information through encoding of the white box encoding table.
Abstract:
PURPOSE: Personalized service providing system and method are provided to maintain anonymity and to offer personalized service by adding an approval function for supporting personalized service to an authentication function using signature. CONSTITUTION: A service providing server(30) requests an attribute certificate according to service request, confirming the validity of the attribute certificate, and determines the offer of the service. An anonymous authentication server(11) provides the anonymous information of a user in response to request. An attribute issuance server(20) transmits the request for issuing attribute certificate of a user terminal(40) to an anonymous certificate server.
Abstract:
PURPOSE: An anonymity authentication and qualification verification method is provided to accomplish authentication on the basis of a short group signature scheme offering anonymity. CONSTITUTION: A user terminal(120) selects a random number as a personal key. In case the personal key ownership verification information of the user terminal is effective, a group management server(110) issues a signature key for the user terminal through a master secret key. The group management server issues a qualification certificate for the user terminal through the issued signature key. A service providing server(130) performs authentication and qualification verification for the user terminal.
Abstract:
An authentication server and a method for processing an authentication-related message are provided to classify various kinds of messages inputted from clients, and to process the classified messages by independent processes or threads, thereby preventing a processing of other messages from being delayed. A connection processor(210) classifies authentication-related messages into a connection message, a session authentication message, and an accounting message, and generates a connection response message by processing the connection message in an independent thread. A session processor(220) receives the session authentication message to classify into an authentication message and an unnecessary session message, and generates a session response message by processing the session message in an independent thread. An authentication processor(230) receives the authentication message to generate an authentication response message by processing the authentication message in an independent thread. An accounting processor(250) receives the accounting message to generate an accounting response message.
