Abstract: A rijndael block cipher apparatus including an operational unit that efficiently performs a round operation for encrypting/decrypting a rijndael block cipher and an encryption/decryption method thereof are disclosed. The rijndael block cipher apparatus is mounted in a mobile terminal such as a cellular phone and a PDA or a smart card, which requires a high-rate and small-sized cipher processor, and can encrypt and decrypt important data that requires security at high speed and perform the round operation with respect to upper 64 bits and lower 64 bits which are divided from 128-bit input data. Thus, the cipher apparatus can reduce the time required for encryption/decryption of the rijndael block cipher and the size of the apparatus.

Abstract: A system and method for preventing illegal use of a device are disclosed. The system for preventing illegal use of a device comprises: a device capable of using a network service through a connected network; a certification authority for performing verification of the device according to an authentication information verification request; and a management server which, if there is a request for the use of the network service from the device, requests the certification authority for the authentication information verification of the device, and if the device is judged to be an illegal device according to a result of verification received from the certification authority, restricts the use of the network service. Accordingly, when a device attempts to access for the use of a service, it is possible to prevent the use of a device judged to be illegal through an authentication information verification procedure.

Abstract: PURPOSE: An anonymous authentication service method is provided to produce an expanded service like an anonymous payment service, etc by providing linkability to a global domain including a plurality of service providing domains. CONSTITUTION: An anonymous authentication service method includes a SetUp process(S200) and a service user joining process(S202). The anonymous authentication service includes a service provider joining process(S204) and a global region connector joining process(S206). The anonymous authentication service includes a group signature signing process(S208) and a group signature verification process(S210). The anonymous authentication service includes a service user tracking process(S212) and an anonymous ID opening process(S214). The anonymous authentication service includes a local-linking process(S216) and a local virtual index or signature information receiving process(S218). The anonymous authentication service includes a global virtual index acquisition process(S220) and a global connection process(S222).

Abstract: An image information process system and a method thereof capable of recognizing identification without including additional information in data transmission are provided to manage a server providing an image photographing terminal and an application service and improve the transmission efficiency of data. One or more image photographing terminal(10) includes a camera. Video data photographed through the camera are provided. An image information manufacturing server(20) generates data of a new form by manufacturing data collected from the image photographing terminal. An application server(30) provides data received from the video information processing server to one or more user terminal. The video information processing server registers one or more image device for photographing and application server information. An identification is obtained to the image photographing terminal and the application server.
