<p>Secure linkage of first and second program modules so that they may authenticate each other and provide security for digital content accessed by one or more of the modules. The method includes storing at least one address of at least one function of the first program module in a file, calling the second program module by the first program module and passing the file to the second program module, verifying integrity by the second program module of the first program module, and calling, by the second program module, a selected function of the first program module using an address obtained from the file when integrity of the first program module is verified. In one embodiment, the first program module may be a digital content player application and the second program module may be an integrity verification kernel for verifying the integrity of the player application. The file may be a signed binary description file including addresses of functions in the first program module.</p> |
