摘要： The present invention is a method and system for accessing digital content stored on a computing device. An agreement between a subscriber and a content provider allows the subscriber to lease the digital content from the content provider, and download the digital content from a content server operated by the content provider. The method retrieves a service ticket for the computing device, and retrieves content rights for the digital content. The service ticket includes authorization data, and a session key, where the authorization data include authorized subscription services for the computing device. The content rights include required subscription services for the digital content and are delivered authenticated with the session key. The method allows access to the digital content when the authorized subscription services included with the authorization data match the required subscription services included with the content rights.

摘要： In a client-server system employing protocols such as RTP (real-time protocol), RTCP (real-time control protocol) and RTSP (real-time streaming protocol) for communicating real-time data stream, a method for using the same security parameters to secure by encryption and/or authentication, communication of the real-time data stream. The method includes establishing two or more security parameters for securing communications during the streaming session; establishing a session identifier associated with the security parameters; transmitting, from client to server, an RTSP message for requesting the real-time data stream, the RTSP message being secured with the security parameters; establishing a streaming session for streaming an RTP message containing the real-time data, the RTP message being secured with the security parameters; transmitting, from client to server, an RTCP protocol message containing statistics relating to the streaming session, the RTCP message being secured with the security parameters, and exchanging any one or more additional RTSP, RTP and RTCP messages in any order, each message being secured with the security parameters which are identifiable with the session identifier.

摘要： Method and apparatus for transferring protected content between digital rights management systems is described. One aspect of the invention relates to importing content from an upstream digital rights management (DRM) system into a device in a downstream DRM system. Data is received that associates at least one device in the downstream DRM system with a rights issuer module (RIM). Authenticity of the data is verified as originating from an entity in a trust hierarchy of the device. If the data is authentic and the device is one of the at least one device associated with the RIM, a ciphertext version of the content and a corresponding content license is accepted from the RIM.

摘要： Method and system for providing client privacy on the Internet when the client requests content from a public application server. The method is well-suited to key management protocols that utilize the concept of tickets. The client name or identity is encrypted in all key management messages where the client is requesting a ticket for a specific application server. The key management messages are between the client and a key distribution center (KDC) and between the client and the specific application server. The KDC does not provide the client name or identity in the clear in such messages. This prevents the client's identity from being linked with the content provided by the specific application server, which results in improved user privacy.

摘要： A secure Internet Protocol (IP) telephony system, apparatus, and methods are disclosed. Communications over an IP telephony system can be secured by securing communications to and from a Cable Telephony Adapter (CTA). The system can include one or more CTAs, network servers, servers configured as signaling controllers, key distribution centers (KDC), and can include gateways that couple the IP telephony system to a Public Switched Telephone Network (PSTN). Each CTA can be configured as secure hardware and can be configured with multiple encryption keys that are used to communicate signaling or bearer channel communications. The KDC can be configured to periodically distribute symmetric encryption keys to secure communications between devices that have been provisioned to operate in the system and signaling controllers. The secure devices, such as the CTA, can communicate with other secure devices by establishing signaling and bearer channels that are encrypted with session specific symmetric keys derived from a symmetric key distributed by a signaling controller.

摘要： A system for restricting playback of an electronic presentation, such as a digital video or song. The system uses a playback time limit that specifies a duration of allowable playback time. The playback time limit is typically longer than the running time of the presentation so that a user is able to use standard transport controls such as pause, stop, rewind, fast forward, etc., that affect the overall playback time needed to view the presentation in its entirety. One approach uses a secure time base that is provided by a server over a network to a client device that includes a playback device. The secure time base is received and used by secure processing within the playback device. This approach allows rendering of the presentation to an output device to be performed by non-secure processing without unduly compromising the security of the system.
摘要翻译：一种用于限制诸如数字视频或歌曲之类的电子演示文稿播放的系统。系统使用播放时间限制，指定播放时间允许的持续时间。播放时间限制通常比演示的运行时间长，以便用户能够使用影响观看演示所需的整体播放时间的标准传输控制，例如暂停，停止，倒退，快进等的全部。一种方法使用由服务器通过网络向包括回放设备的客户端设备提供的安全时基。通过播放设备内的安全处理来接收和使用安全时基。该方法允许将呈现呈现给输出设备以通过非安全处理来执行，而不会不适当地危及系统的安全性。
