摘要： Systems and methods are disclosed that authenticate devices or users, and enable playback of secured streaming content through a media player. In one embodiment, the invention is a system for receiving secure content over an unmanaged network, including a security application configured operate on a user device with access to a network, where the security application is configured to receive a request for playlist data from the media player, send a playlist request to a content server, receive playlist data from the content server, send playlist data to a media player, receive a security access request from the media player, send a security access request to a security server, receive security access data from the security server; and send security access data to a media player.

摘要： Systems and methods for synchronized key derivation across multiple conditional access servers are disclosed. In one embodiment, a method for synchronized key derivation to provide playback devices with derived keys for decrypting content includes receiving a request for a first derived key that includes a first asset identifier than identifies a piece of content and a first playback position within the content, determining a first content key starting position and first derived key starting position within the content using the first playback position, where the key starting positions precede the first playback position, determining whether a first content key associated with the first asset identifier and first content key starting position is stored, retrieving the first content key using the first asset identifier and first content key starting position, generating a first derived key using the first content key and first derived key starting position, and sending the derived key.
摘要翻译：公开了用于跨多个条件访问服务器的同步密钥导出的系统和方法。在一个实施例中，用于为再现设备提供用于解密内容的导出密钥的同步密钥导出的方法包括：接收对包括第一资产标识符的第一导出密钥的请求，该第一资源标识符不是识别内容内的一条内容和第一播放位置，使用第一播放位置确定内容内的第一内容密钥开始位置和第一派生密钥开始位置，其中密钥起始位置在第一重放位置之前，确定与第一资产标识符和第一内容密钥相关联的第一内容密钥是否开始存储位置，使用第一资产标识符和第一内容密钥起始位置检索第一内容密钥，使用第一内容密钥和第一派生密钥起始位置生成第一导出密钥，以及发送导出密钥。
