Abstract
A method for accessing content is provided. In this method, a first parameter associated with a license is retrieved. The license is associated with the content. A second parameter associated with the content also is retrieved. With the first and second parameters, a third parameter based on the first and second parameters is generated. The third parameter is configured for use in decrypting the content and the content can be accessed based on the third parameter. An apparatus is also provided comprising a memory and a processor in communication with the memory. The processor is configured to retrieve a first parameter associated with a license; retrieve a second parameter associated with the encrypted content; generate a third parameter based on the first and second parameters; and access the encrypted content based on the third parameter.
Claims
AMENDED CLAIMS received by the International Bureau on 29 July 2008 (29.07.2008)
1. A method for accessing content, comprising: retrieving a first parameter associated with a license, the license being associated with the content; retrieving a second parameter associated with the content; generating a third parameter based on the first and second parameters; and accessing the content based on the third parameter, the third parameter being configured for use in decrypting the content.
2. The method of claim 1, wherein the accessing the content comprises: transmitting the third parameter and a request for the content; and receiving the content
3. The method of claim 1 , further comprising: encrypting the third parameter based on a variable to define a session ticket, the variable being configured to change at a session; and accessing the content based on the session ticket
4. The method of claim 3, wherein the variable is configured to change randomly at the session.
5. The method of claim 1, wherein the license and the content are stored in a memory device.
6. The method of claim 1, wherein the first parameter is a number.
7. The method of claim 6, wherein the number is randomly generated.
8. The method of claim 1, wherein the second parameter is derived from a reference to a cryptographic key and the first parameter.
9. The method of claim I , wherein the second parameter is derived from an authentication key and the first parameter.
10. The method of claim 1 , wherein the second parameter is derived from a cryptographic nonce and the first parameter.
11. The method of claim 1 , wherein the third parameter is a reference to a cryptographic key.
12. The method of claim 1 , wherein the third parameter is an authentication key,
13. The method of claim 1 , wherein the third parameter is a cryptographic nonce, the cryptographic nonce being used to generate a cryptographic key,
19. A method for accessing content stored in a memory device, comprising: retrieving a first number from a license, the license being associated with the content, the first number being randomly generated; retrieving a parameter from the content, the parameter being derived from a reference to a cryptographic key and the first number; generating the reference to the cryptographic key based on the first number and the parameter; and accessing the content based on the reference to the cryptographic key.
20. The method of claim 19, further comprising; generating a session ticket based on the reference and a second number, the second number being configured to change at a session; and accessing the content based on the session ticket.
21, The method of claim 19, wherein the content is encrypted using the cryptographic key.
22. The method of claim 19, wherein the parameter is located in a header of the content.

39. The computing device of claim 37, wherein the license and the content are stored in a memory device, the memory device being configured to be coupled with the computing device.
40. The computing device of claim 37, wherein the first parameter is derived from the reference to the cryptographic key and the second parameter.
41. The computing device of claim 37, wherein, the second parameter is a number that is randomly generated.
42. A computing device, comprising: a memory; and a processor in communication with the memory, the processor being configured to: retrieve a first number from a license that is associated with a content, the first number being randomly generated, retrieve a parameter from the content, the parameter being derived from a reference to a cryptographic key and the first number, generate the reference to the cryptographic key based on the first number and the parameter, and access the content based on the reference to the cryptographic key.
