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 and apparatus of protecting digital content within a domain is provided. if a device registered with a domain withdraws from the domain, a domain key used in the domain before withdrawal of the device is updated to a domain key which cannot be used by the device; and the domain key not exposed to the device is transmitted to a plurality of devices currently registered with the domain so that only the currently registered devices have the most recent domain key. Therefore, devices not registered with the domain and devices which previously registered with the home domain but withdrawn from the home domain can be prevented from using digital content currently shared within the domain. In addition, registered devices that withdraw from the home domain may use digital content legitimately downloaded from the home domain before they withdrew from the domain.
摘要翻译：提供一种保护域内数字内容的方法和装置。如果注册域的设备从域中退出，则在提取设备之前在域中使用的域密钥被更新为设备不能使用的域密钥; 并且未暴露于设备的域密钥被发送到当前在域中注册的多个设备，使得只有当前注册的设备具有最新的域密钥。因此，可以防止未注册到域的设备和以前在本地域注册但从归属域撤回的设备使用当前在域内共享的数字内容。此外，退出本地域的注册设备可以在他们退出域之前使用从归属域合法下载的数字内容。
