    • A portable storage medium for storing and using DRM contents, and a method and a system for implementing the same are provided to prevent illegal copy of encrypted digital contents like a digital album by safely storing a portable device certificate and right information for the encrypted digital information based on PKI. A portable device(200) downloads and plays the contents encrypted by DRM. The portable storage medium(100) includes a memory storing the contents encrypted by the DRM and the right information for the encrypted contents. The portable storage medium verities a PKI-based certificate received from the portable device, generates a session key for forming a communication channel with the portable device, and encrypts/transmits the session key to the portable device. The portable device encrypts the right information by using the session key and transmits the encrypted right information to the portable storage medium. The portable storage medium decrypts the right information by using the session key, encrypts the decrypted right information by using a card key of the portable storage medium, and stores the encrypted right information to the memory.
    • 提供了用于存储和使用DRM内容的便携式存储介质,以及用于实现该内容的方法和系统,以通过安全地存储便携式设备证书和用于加密数字信息的正确信息来防止诸如数字相册的加密数字内容的非法复制 基于PKI。 便携式设备(200)下载并播放通过DRM加密的内容。 便携式存储介质(100)包括存储由DRM加密的内容的存储器以及加密内容的正确信息。 便携式存储介质验证从便携式设备接收到的基于PKI的证书,生成用于与便携式设备形成通信信道的会话密钥,并将会话密钥加密/发送到便携式设备。 便携式设备通过使用会话密钥加密正确的信息,并将加密的权利信息发送到便携式存储介质。 便携式存储介质通过使用会话密钥解密正确的信息,通过使用便携式存储介质的卡密钥对解密的权利信息进行加密,并将加密的权利信息存储到存储器中。

    • PURPOSE: A portable reproducing device and a method of controlling the same are provided to prevent a user without a proper right from watching learning contents. CONSTITUTION: A content storing unit(104) stores multimedia contents. A content reproducing unit(105) reproduces the multimedia contents. A user authentication module(107) is activated to determine whether an user authentication unit(108) decides whether a user is registered. A controller(112) activates the content reproducing unit so that the multimedia contents are reproduced. If reproduction about the multimedia contents ends, the controller stores reproduction history information about the multimedia contents in a content history storage(106).
    • 目的:提供一种便携式再现装置及其控制方法,以防止用户没有正确权限观看学习内容。 内容存储部(104)存储多媒体内容。 内容再现单元(105)再现多媒体内容。 用户认证模块(107)被激活以确定用户认证单元(108)是否确定用户是否被注册。 控制器(112)启动内容再现单元,从而再现多媒体内容。 如果关于多媒体内容的再现结束,则控制器将关于多媒体内容的再现历史信息存储在内容历史存储器(106)中。

    • Portable memory media for recording and using contents to which DRM(Digital Rights Management) is applied are provided to prevent illegal copying of digital contents encrypted by the DRM such as a digital album by recording and using the contents encrypted by the DRM and information relating thereto in the portable memory media. Portable memory media includes an interface driver(110), a power sensing unit(120), a control unit(140), a register(130), a memory interface unit(150), and a memory(160). The interface driver allows the portable memory media and a host device to be physically connected to each other. The power sensing unit supplies power to the portable memory media by sensing the power when connecting the host device and the portable memory media to each other through the interface driver. The control unit engages in communication with the host device, authentication, and encryption/decoding. The memory interface stores contents and right information or transmits the stored data to the control unit. The portable memory media and the host device authenticate each other by a predetermined authentication unit.
    • 提供用于记录和使用DRM(数字版权管理)应用的内容的便携式存储介质,以防止通过记录和使用由DRM加密的内容和与其相关的信息来非法复制DRM等加密的数字内容,例如数字相册 在便携式存储介质中。 便携式存储介质包括接口驱动器(110),功率感测单元(120),控制单元(140),寄存器(130),存储器接口单元(150)和存储器(160)。 接口驱动器允许便携式存储介质和主机设备彼此物理连接。 功率感测单元通过在通过接口驱动器将主机设备和便携式存储介质彼此连接时感测电力来向便携式存储介质供电。 控制单元与主机设备进行通信,认证和加密/解码。 存储器接口存储内容和权利信息,或将存储的数据发送到控制单元。 便携式存储介质和主机设备通过预定认证单元进行认证。
