    Abstract: 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.

    Abstract: An apparatus and a method for managing identity data are disclosed, which can recover lost or deleted ID data stored in a user terminal and prevent a malicious user to plagiarize a user's ID. The apparatus includes a user ID management device (1), a back-up server (2) and a website system (3). The user ID management device (1) installed in a user's terminal allows ID data to be used on a website. The user ID management device (1) includes an ID management unit (10), a data storing unit (12), a back-up requesting unit (14) and a recovery requesting unit (16). A back-up server (2) backs up and stored ID data from the user ID management device (1). The back-up server includes a data storing unit (20), a back-up processing unit (22), a recovery processing unit (24), a suspension receiving unit (26) and a suspension requesting unit (28). A website system (3) includes a user account management unit (30), a suspension processing unit (32) and a recovery processing unit (34).

    Abstract: The present invention relates to a user terminal (100) with an identify selector and a method for an identity authentication using the identify selector of the same, in which when a web service makes a request to a web service providing server (300) using a virtual personal identification information issued from an identity authentication server (200), a corresponding user identity is authenticated between the user terminal and the identity authentication server (200) using the identity selector according to the request of the web service providing server (300). The present invention has advantages that it can solve the problem of inputting an ID and password within the range such that the I-PIN or SMAL service protocol is not changed, but the subscribed I-PIN or SAML service providing site cannot be easily copied and a phishing problem by simplifying a log-in process for identity authentication by adding the identity selector.

    Abstract translation: 本发明涉及一种具有标识选择器和使用其识别选择器进行身份认证的方法的用户终端（100），其中，当Web服务向web服务提供服务器（300）请求时，使用 从身份认证服务器（200）发出的虚拟个人识别信息，根据web服务提供服务器（300）的请求，使用身份选择器在用户终端和身份认证服务器（200）之间认证相应的用户身份。 本发明的优点在于可以解决在I-PIN或SMAL业务协议不改变的范围内输入ID和密码的问题，但是不能轻易复制订阅的I-PIN或SAML服务提供站点， 通过添加身份选择器简化用于身份认证的登录过程的网络钓鱼问题。
