摘要： A method and system for attaching a title key to encrypted content for synchronized transmission to, or storage by, a recipient is provided. Specifically, under the present invention, an elementary media stream is parceled into content units that each include a content packet and a header. The content packets are encrypted with one or more title keys. Once the content packets have been encrypted, the title keys are themselves encrypted with a key encrypting key. The encrypted title keys are then attached to the corresponding encrypted content packets for synchronized transmission to a recipient.

摘要： The present invention provides a method, system and program product for modifying content usage conditions during broadcast content distribution. Specifically, the present invention allows protected (e.g., encrypted, secured, etc.) content to be received along with content usage conditions, an encrypted combination of the content usage conditions and a title key (e.g., a MAC), and a key management block. Using the key management block, a key encrypting key can be determined for decrypting the combination. Once the combination is decrypted, the content usage conditions can be modified (e.g., edited, added to, etc.).

摘要： A method, system and program product for managing a size of a key management block (KMB) during content distribution is provided. Specifically, a first KMB corresponding to a first subtree of devices is received along with content as encrypted with a title key. If a size of the first KMB exceeds a predetermined threshold, a second subtree will be created. A second KMB corresponding to the second subtree of devices will then be generated. The second KMB contains an entry revoking the entire first subtree of devices and, as such, is smaller than the first KMD. Any compliant devices from the first subtree are migrated to the second subtree.

摘要： A trusted Java virtual machine provides a method for supporting tamper-resistant applications, ensuring the integrity of an application and its secrets such as keys. The trusted Java virtual machine verifies the integrity of the Java application, prevents debugging of the Java application, and allows the Java application to securely store and retrieve secrets. The trusted Java virtual machine environment comprises a TrustedDictionary, a TrustedBundle, an optional encryption method for encrypting and decrypting byte codes, and an underlying trusted Java virtual machine. The encrypted TrustedDictionary protects data while the TrustedBundle protects programming code, allowing applications to store secret data and secure counters. The application designer can restrict TrustedBundle access to only those interfaces that the application designer explicitly exports. The open source code may optionally be encrypted. Secrets required by the open source programming code of the application are encrypted in TrustedDictionary.

摘要： Enhanced multimedia content on physical media interacts with the user through a media player and the Internet. Enhanced multimedia utilizes IDs for pieces of content on the media and a media key block. On the enhanced media is a file with a list of URLs. As the enhanced media plays a section requiring a set of keys for decryption, the media player accesses the URL for that section and obtains the decryption key. The decryption key may be purchased or provided for free. Secure encryption and transmission of these keys is accomplished by broadcast encryption using a media key block. Each media has a unique set of keys that allow the media player to process the media key block; however, each media follows a unique path through the media key block. All legitimate media players obtain the media key; circumvention devices cannot decipher the media key block.

摘要： Provided are techniques for the creation and storage of an archive for binding IDs corresponding to a cluster of devices that render content protected by a broadcast encryption scheme. When two or more clusters are merged, a binding ID corresponding to one of the clusters is selected and a new management key is generated. Binding IDs associated with the clusters other than the cluster associated with the selected binding ID are encrypted using the new management key and stored on a cluster-authorized device in a binding ID archive. Content stored in conformity with an outdated binding ID is retrieved by decrypting the binding ID archive with the management key, recalculating an old management key and decrypting the stored content.
摘要翻译： 提供了用于创建和存储用于绑定ID的存档的技术，所述绑定ID对应于呈现由广播加密方案保护的内容的设备的集群。 当两个或更多个集群合并时，选择与一个集群对应的绑定ID，并生成新的管理密钥。 与除与所选绑定ID相关联的集群之外的集群相关联的绑定ID使用新的管理密钥加密并存储在绑定ID归档中的集群授权设备上。 通过用管理密钥解密绑定ID档案，重新计算旧的管理密钥并解密所存储的内容来检索与过时的绑定ID一致的存储的内容。
