摘要： A method of encrypting a unique cryptographic entity (UCE), where a client device receives a global-key (GK-) encrypted UKD comprising a GK-encrypted UCE and a GK-encrypted unit key number (UKN). The client device verifies that the GK-encrypted UKN is the same as a pre-provisioned value and then decrypts the GK-encrypted UKD using a global key (GK). The client device then re-encrypts the decrypted UKD using a device user key (DUK) to determine a DUK-encrypted UCE and a DUK-encrypted UKN. The DUK-encrypted UKN is verified as not equal to the GK-encrypted UKN. The DUK-encrypted UKN is then appended to the DUK-encrypted UCE to form a DUK-encrypted UKD and stored in a memory.
摘要翻译：一种加密唯一密码实体（UCE）的方法，其中客户端设备接收包括GK加密的UCE和GK加密的单元密钥号码的全局密钥（GK）加密的UKD（ UKN）。客户端设备验证GK加密的UKN与预先配置的值相同，然后使用全局密钥（GK）解密GK加密的UKD。客户端设备然后使用设备用户密钥（DUK）重新加密解密的UKD以确定DUK加密的UCE和DUK加密的UKN。 DUK加密的UKN被验证不等于GK加密的UKN。然后将DUK加密的UKN附加到DUK加密的UCE上以形成DUK加密的UKD并存储在存储器中。

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.
摘要翻译：当客户端请求来自公共应用服务器的内容时，用于在因特网上提供客户端隐私的方法和系统。该方法非常适合使用票证概念的密钥管理协议。客户端名称或标识在客户端为特定应用程序服务器请求票证的所有密钥管理消息中进行加密。密钥管理消息位于客户端与密钥分发中心（KDC）之间以及客户端与特定应用程序服务器之间。 KDC不会在此类消息中明确提供客户名称或身份。这可以防止客户端的身份与特定应用程序服务器提供的内容链接，从而提高用户隐私。

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： A process may be utilized by the DVR. The process receives a plurality of segments of a set of content and a plurality of corresponding content rule sets. Further, the process provides one or more instructions to record and encrypt the plurality of segments of the set of content on a storage medium. In addition, the process provides the plurality of content rule sets to the DRM component to be inserted into a locally generated and secured content license associated with the encryption of the set of content. The secured content license includes a master key and a list of the plurality of corresponding content rule sets that have been received in order of reception. The process receives a plurality of marker tokens from the DRM component in order to facilitate trick mode playback.

摘要： The present invention reduces the exposure of keying material to intermediary devices in a communication channel between first and second servers. In one embodiment(100), a second server receives a first half of media stream keys from a first server. The second server uses a Kerberos-based Application Request and tickets to communicate the second half of the media stream keys to the first server. Using this approach, the exposure of the media stream keys is reduced to only the servers.

摘要： A system for rating security levels a device according to the characteristics of functions executing within secure hardware components in the device. The security level of a host is placed in a digital certificate along with a corresponding private key at the time of manufacture of a device. The digital certificate can be provided to an inquiring device so that more comprehensive systme-wide security levels can be communicated and maintained. Where a network uses ticket-based key management protocols, the security rating, or level, is transferred from the certificate to an issued ticket. Inquiring devices can then check security levels of target devices by using certificates or tickets and perform transfers or grant authorizations accordingly. In a preferred embodiment a security ratings system uses six levels of security. The levels are structured to include characteristics about a device’s processing. That is, the levels provide information on the amount and type of sensitive processing that can occur in non-secure (or low security) circuitry or components within a device. This gives a bette indication of how prone a device is to threats that may be of particular concern in content delivery networks. Additional qualifiers can be optionally used to provide further information about a security level. For example, the degree of handling time management processing within secure hardware and whether a particular codec, watermarks of fingerprings are supported within secure hardware can each be represented by a policy qualifier.

摘要： An improved subset-difference method is provided. The improved method uses the value of a current content key to help generate the requisite difference keys. The requisite difference keys are then used to encrypt the next content key which will be delivered only to users who are supposed to remain in the group. Users who have the current content key are then able to generate the requisite difference keys which they can then use to decrypt the next content key. Using the decrypted next content key, the users are then able to continue to receive contents. Since previously revoked users do not have the current content key, they are unable to determine the next content key and thus are prevented from receiving future contents.
