    摘要: A method and system (100) for providing third party authentication when requesting content and/or services from an application server (106). The method is applicable to key management protocols that utilize the concept of tickets. The method and system include a client (102) being coupled with a third party application server (107), wherein the client submits a request for content from the third party application server and the third party application server returns requested information and corresponding authentication. The client further couples with a first application server (106), wherein the client submits a key request (KEY_REQ) including the third party server information and corresponding authentication to the first application server. The first application server authenticates the third party server information and verifies client authorization based on third party information. The first application server returns a key reply (KEY_REP) if the third party server information is authenticated and client authorization is verified.

    摘要: Systems and methods are disclosed for providing certificate status information about a certificate includes receiving, at a Certificate Status Information Protocol (CSIP) proxy device the certificate identity information about the certificate of the second device. Then determining, using the CSIP proxy device, whether the certificate status information is stored in a CSIP proxy device memory. If the certificate status information is not stored in the CSIP proxy device memory, creating a CSIP request based on the certificate identity information and sending the CSIP request, including the certificate identity information, to a CSIP responder computer outside the local network domain. If the certificate status information is stored in the CSIP proxy device memory, sending the certificate status information to the first device. Also, a system and method are disclosed for using a CSIP responder computer.

    摘要: A session rights object and authorization data are used for defining a consumer's access right to a media content stream. The access rights are determined at a caching server remotely located from the consumer rather than locally at the end user site. In a first aspect, in a computing network having a content provider, a key distribution center, a caching server and a client, a method for controlling client access to a real-time data stream from the caching server, is disclosed. The method includes receiving, by the client, a session rights object from a content provider, the session rights object defining access rules for accessing the real-time data stream; receiving, by the client, authorization data from the key distribution center, the authorization data defining the client's access rights to the real-time data stream; forwarding to the caching server the session rights object and the authorization data; comparing, by the caching server, the session rights object with the authorization data to determine client authorization; and if the client is authorized, streaming, by the caching server, the real-time data stream to the client.

    摘要: A process composes a content license for a set of content. The content license has a static portion and a dynamic portion. Further, the process inserts a master key into the static portion. In addition, the process inserts a plurality of content rule sets of values into the dynamic portion and composes a unique content encryption key for each segment of content associated with one of the content rule sets of values as each of the content rule sets of values is sequentially received during recording of the content. The unique content encryption key is based on the master key and at least a subset of the content rule set of values for a corresponding segment of the content. The unique content encryption key is utilized for encryption of each segment of the content to generate a plurality of encrypted content segments for storage on the storage medium.
