Method and apparatus for secure content delivery over broadband access networks

A method, comprising:

• receiving by a client computer system, an activator, said activator providing cryptographic data for decrypting content title data, said cryptographic data embedded in obfuscated bytecode to inhibit unauthorized extraction of the cryptographic data, said obfuscated bytecode implements executable instructions for decryption of content data;
• receiving authorization data, the authorization data identifying a time period in which the content title remains in executable form;
• receiving the content title data, the content title data including content, a downloaded file system, and simulated registry values for an executing instance of the content;
• executing a virtual machine, the virtual machine including executable instructions for interpreting and executing obfuscated bytecode;
• executing, by the virtual machine, the accessed activator in the form of the obfuscated bytecode to generate the cryptographic data for decrypting content title data;
• decrypting the content title data using the generated cryptographic data;
• mounting the downloaded file system;
• executing, by using information stored in the downloaded file system, the content;
• intercepting an operating system request for a registry value associated with the execution of the content;
• and
• sending a simulated registry value to the operating system thereby simulating an instillation of the content on the client.

A method comprising:

• generating, by a computer system, an activator, the activator including cryptographic data for content title data in obfuscated bytecode to inhibit unauthorized extraction of the cryptographic data, wherein the obfuscated bytecode implements executable instructions for decrypting content title data, the obfuscated bytecode consumable by a virtual machine that is configured to interpret and execute the obfuscated bytecode to obtain the cryptographic data for decrypting the content title data;
• storing the generated activator in the form of the obfuscated bytecode;
• wherein the activator includes authorization data, the authorization data identifying a time period in which the content title remains in executable form, said generated cryptographic data being valid only for the identified time period;
• wherein the content title data includes content, a downloadable file system that includes files associated with the content, and simulated registry values;
• and
• wherein the content is configured to be executed by using the files stored in the downloadable file system and using the simulated registry values to simulate an instillation of the content in a client file system.
