    摘要: A method of receiving a session key in a home network and a method of reproducing content using the same. The method of receiving a session key from a home server in a home network, includes: (a) whenever one of members of the home network changes, receiving and storing the session key and a session version indicating a session key generation sequence; (b) receiving a license necessary for reproducing predetermined content; and (c) determining a session key necessary for reproducing the predetermined content based on an encoding session version (ESV), which is a session version extracted from the license, and the stored session version. A home server transmits a session key and a session version to a user device whenever a subscriber to a home network changes, and the user device determines a session key using the session version, thereby performing a variety of domain administration by freely transmitting content between user devices.

    摘要: A method for transmitting content to a user device from a home server in a home network is provided. The method includes: receiving an allocated user public key and a user private key of a user to whom the home server belongs; generating an arbitrary session public key and a session private key, generating an encrypted session private key by encrypting the session private key using a device public key that is a public key of the user device, and transmitting the encrypted session private key to the user device; and transmitting the content encrypted using a predetermined content key and a content key encrypted using the session private key to the user device. According to the method, by binding the content to each user, instead of to each device, the content can be safely and conveniently shared.

    摘要: A method of and an apparatus for copying and decrypting encrypted digital data. The method of copying encrypted digital data includes encrypting a first media key block to be used for decryption of the encrypted digital data using a predetermined key of a second information storage medium and storing the encrypted digital data and the encrypted first media key block in the second information storage medium. Security of data encryption is heightened by not discarding an encryption key used for an initial encryption, encrypting the encryption key used for initial encryption using another encryption key used for a second encryption, and storing the encrypted encryption key with the data. Also, since unnecessary decryption and encryption of data are not repeated, the time required for copying data is reduced, and since data is transferred between apparatuses in an encrypted state, a security level is higher.

    摘要: Provided are a method of recording/reproducing data under control of a domain management system. The method includes extracting, from the write command, domain management information regarding the predetermined domain and contents, and copy control information specifying an extent of copying the contents within the predetermined domain; recording the extracted domain management information on the storage medium; generating a domain-bound flag that is used to determine whether the recording apparatus which records the contents on a storage medium is present in the predetermined domain, based on the extracted copy control information; and recording the domain-bound flag and the contents on the storage medium. Accordingly, it is possible to record contents, recording of which is limited within a predetermined domain, on a storage medium outside a slave under control of a domain management system, while preventing the contents from being reproduced within other domains.

    摘要: Provided are an information storage medium from which a total number of times that data can be reproduced is limited, a method and apparatus for recording data on the information storage medium, and a method and apparatus for reproducing data from the information storage medium. The information storage medium includes a data zone storing user data, and a control information zone storing control information regarding controlling a number of times that the user data can be reproduced. Accordingly, a content provider who provides content such as a movie can create various types of business models by recording content on the aforementioned information storage medium, and selling it at a cheaper price. Further, control information is recorded on the information storage medium or a write once zone of the information storage medium before recording content or user data thereon, thereby preventing the control information from being changed or deleted.
