摘要:
The prevent invention relates to a portable mobile apparatus for a user for providing a supplementary service and a method for providing a supplementary service by using the same, and more particularly, to an apparatus and a method for providing supplementary enhanced services by using an application run in a portable mobile terminal when the portable mobile terminal such as a cellular phone or a smart phone is used for a service through short-range RF communication. The present invention can provide a variety of supplementary services to the user by using an operation function included in the application in the mobile terminal when performing the services through the short-range RF communication. Specifically, it is possible to automate the supplementary function or provide convenience to the user and interact with the user.

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 for cooperatively operating a Web browser and a local resource in a mobile terminal includes a Web browser for receiving a Web page requesting a local resource from a Web server connected to the mobile terminal; and a gateway server for controlling the local resource with parameters of the Web page and transmitting information regarding execution results of the local resource to the Web server by way of the Web browser. The parameters of the Web page include at least one of an ID of the Web server, a callback address (CallbackURL), a requested local resource function, and signature information.

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.

The present invention provides a method of validating a certificate by a certificate validation server using certificate policy and certificate policy mapping in a public key infrastructure (PKI). If the certificate validation server receives, from a client, an object certificate to be validated, a certificate of a certification authority which the client trusts, and a certificate policy which will be applied to validation of the object certificate, and receives a request for validation of the object certificate, the certificate validation server creates a certification path for the object certificate in response to the request. The certificate validation server validates the created certification path using a certificate policy mapping table if the validation of the object certificate is allowed, and then transmits a result message to the client according to the result of the validation of the certification path.
