Provided are a mobile terminal for sharing resources, a method of sharing resources within a mobile terminal and a method of sharing resources between a web server and a terminal. The mobile terminal for sharing resources includes a web browser using a web standard protocol to display a first random value, an authentication number, and a Distinguished Name (DN) of web server transferred from the web server after it has been determined that there is no key information in a cookie; and a resource when the first random value and the DN are received from the web browser, being terminated after storing the first random value and the DN, and when the resource is re-executed and the authentication number is input by a user, verifying the first random value, generating a second random value and a shared key from the first random value and generating a symmetric key using a part of the shared key, wherein the shared key is generated from the second random value based on the symmetric key, and the symmetric key is identical to a symmetric key of the web server generated from a part of the symmetric key, and the web browser and the resources are operated by an execution unit.

A key tree construction and key distribution method for hierarchical role-based access control, includes: constructing a key tree including relationships between a hierarchical structure of role groups and data; performing encryption and decryption of data keys and role keys; and generating a key table, in which the data keys required to decrypt encrypted data and the role keys required to decrypt encrypted data keys are stored, with reference to the key tree. Further, the key tree construction and key distribution method for hierarchical role-based access control includes performing management such that a specific role group can obtain a data key by performing decryption based on its own role key by using both the key tree and the key table.

An apparatus and method for providing a service that securely and easily shares personal information using a signed callback uniform resource locator (URL) message in a mobile terminal environment are provided. The mobile terminal providing a personal information sharing service using a signed URL message includes; a personal information sharing service module which receives a message that includes a first callback URL and a personal information sharing request and is signed using a private key of a server, and creates a second callback URL by adding a user response result in response to the personal information sharing request to the first callback URL; and an authentication module which verifies a signature of the message using a public key of the server, and signs the second callback URL using a user private key.

A method and system for transmitting and receiving user's personal information using an agent are provided. An information management server managing user's personal information provides an agent including user's personal information in response to a user's personal information request message from a client. A client receives the agent and requests user's personal information from the agent. Then, the agent determines whether the client is authorized and provides the user's personal information to the client when it is determined that the client is authorized. Accordingly, the user's personal information is safely managed and transmitted.

Provided are a transactions certification method and system to protect privacy on details of electronic transactions, the method comprising the operations of: a) receiving and registering client information which is encoded so that a client cannot be identified; b) receiving and storing transactions details of a client including a client transactions identifier encoded by the service provider server; c) after receiving client certification information for client certification, performing client certification by comparing the client information previously registered in the operation a) with the received client certification information; d) receiving a client transactions identifier for searching transactions details of a client when the client certification is performed in the operation c), and determining whether the client transactions identifier and the client transactions identifier previously stored in the operation b) are identical with each other; and c) generating a message corresponding to the transactions details of the client and sending the generated message to the client when it is determined that the client transactions identifiers are identical with each other in the operation d). Accordingly, the transactions details can be managed while protecting privacy on the transactions details of the client.

The present invention provides a method for modifying validity of a certificate in a public key infrastructure (PKI)-based authentication system, which is capable of performing online suspension, recovery and revocation of a certificate between a user system and a certificate authority by executing user authentication with guaranteed reliability using user biometric information. Accordingly, there is no need for the user to personally visit a registration authority or certificate authority to modify the certificate validity. The user can easily modify the certificate validity using his/her user system connected online to the certificate authority.

Provided are an apparatus and method for managing identity information. The apparatus includes a contract detail manager managing details of an identity information sharing contract made between a user and an identity provider (IdP) wanting to provide identity information about the user, and details of an identity information sharing contract made between the user and an identity consumer (IdC) wanting to be provided with the identity information about the user, an IdP selector selecting an IdP capable of providing the identity information about the user based on the details of the sharing contract when a request for the identity information about the user is input from the IdC, and an information provider obtaining information according to the identity information request from the selected IdP, and providing the obtained information to the IdC. The apparatus and method can solve a problem that all of a user's identity information is provided to an IdC according to the user's comprehensive agreement.
