摘要： A digital rights management architecture for securely delivering content to authorized consumers. The architecture includes a content provider and a consumer system for requesting content from the content provider. The content provider generates a session rights object having purchase options selected by the consumer. A KDC thereafter provides authorization data to the consumer system. Also, a caching server is provided for comparing the purchase options with the authorization data. The caching server forwards the requested content to the consumer system if the purchase options match the authorization data. Note that the caching server employs real time streaming for securely forwarding the encrypted content, and the requested content is encrypted for forwarding to the consumer system. Further, the caching server and the consumer system exchange encrypted control messages (and authenticated) for supporting transfer of the requested content. In this manner, all interfaces between components are protected by encryption and/authenticated.

摘要： According to one embodiment of the invention, a free preview of a program can be provided to client computers in a multicasting system. This can allow viewers in the multicasting system to view a first portion of the program before deciding whether to order the program content. According to another embodiment, various distribution methods can be accomplished using encyrption keys to distribute program content. According to yet another embodiment, an initial viewing period can be provided to allow negotiation of the encryption keys. According to another embodiment, rules and conditions for providing content in a multicasting environment can be utilized.

摘要： A method and apparatus for generating cryptographic keys in a cryptographic system. First, a key is generated by reducing the distribution space of the cryptographic key (320). Next, a key is generated by increasing the distribution space of the reduced space key (330). This reduced-increased-space key is used to encrypt information (340). Persons that know the specific distribution reducing and expanding procedures would required much reduced work factor to decrypt information encrypted by these keys. Cryptographic keys generated by this method and apparatus would meet U.S. Export limitations on keys as applied to cryptographic applications and technologies.

摘要： A method for authenticating a string of data stored remotely from the processor. A bifurcated hash routine can be utilized to provide a check root along with a putative new root for a revised string of data. The check root can be compared with the previously determined initial root. If the check root matches the initial root, the new root is accepted in view of the fact that it was computed concurrently with the check root.
