    摘要： An apparatus for dynamically managing a group transient key (GTK) and a method thereof in order to perform setting of a GTK successfully by an access point (AP). Wherein, the AP checks security state of a plurality of mobile stations (MS)s connecting to the AP, and exchanges and sets a GTK for authenticated MSs. The apparatus for managing a GTK in a wireless LAN system, the apparatus including: a GTK generation timing deciding unit for deciding timing to generate a GTK based on security state of an MS; a GTK generating unit for generating a GTK according to the GTK generation timing decided in the GTK generation timing deciding unit; a GTK exchanging unit for exchanging the GTK generated in the GTK generating unit based on the security state of the MS; and a GTK setting unit for setting the GTK based on the number of MSs exchanged the GTK.

    摘要： There is provided an anonymous service method of providing local linkability. The anonymous service method providing local linkability according to exemplary embodiments of the invention, an anonymous authentication operation based on a short group signature is performed, for which the concept of a local linkability is introduced to secure linkability within the same service domain. Namely, in the interior of a service provider, a virtual index having a fixed value is calculated for each service user, and in this case, although a plurality of service providers collude with each other, they cannot calculate a virtual index having the same value, whereby the linkability can be secured within the same service domain but not within the interiors of different service domains.

    摘要： An anonymous authentication-based private information management (PIM) system and method are provided. The PIM method includes receiving an anonymous certificate not including user information from an anonymous certification authority; generating an anonymous document including the anonymous certificate and some of the user information; and providing the anonymous document to a web service provider so as to be authenticated and thus provided with a web service by the web service provider. Thus, only a minimum of user information may be provided to the web service provider. In addition, it is possible to strengthen a user's right to self-determination and control over the exposure and use of his or her personal information by allowing a user to manage his or her own personal information or entrusting the PIM server to manage user information. Moreover, it is possible to protect the privacy of a user by preventing the exposure of user information.
