    摘要: A method of playing back content based on digital rights management (DRM) between a portable storage and a device and a portable storage for the same are provided. The method of playing back content using a portable storage includes requesting the portable storage to transmit a right to play back content protected through digital rights management (DRM), receiving the right to play back the content protected through DRM from the portable storage, and informing the portable storage of completion of the playback when a playback of the content protected through DRM using the right is completed.

    摘要: A digital rights management (DRM) structure, a portable storage device, and a contents management method using the portable storage device are provided to facilitate the move of a rights object or encrypted content. The digital rights management structure includes a security section comprising private key information and cryptographic method which are needed to decrypt information that has been encrypted by a host device, a restriction section comprising authentication information needed for authentication with the host device and rights object information regarding content, and a data section comprising encrypted content which the host device attempts accessing.

    摘要: For digital rights management (DRM), a method for performing authentication between a device and a portable storage, which is performed by the device, includes transmitting a first key to the portable storage, receiving a third key and a first encrypted random number obtained by encrypting a first random number using the first key from the portable storage and decrypting the first encrypted random number using a second key related with the first key, generating a second encrypted random number by encrypting a second random number using the third key and transmitting the second encrypted random number to the portable storage, and generating a session key using the first random number and the second random number. The technique guarantees secure authentication between the device and the portable storage for DRM.

    摘要: A portable storage device and method of managing a file in the portable storage device are provided. The portable storage device includes a control module sorting digital rights management data from received data and forming a file comprising the digital rights management data, and a storage module storing the file. The method includes sorting digital rights management data from received data, forming a file comprising the digital rights management data, and storing the file in a storage module. Accordingly, files can be securely managed to be suitable to DRM.
