Abstract
A licensing attribute certificate enables a trusted computing base to enforce access to a computing resource by a computer application. The licensing attribute certificate can contain enforcement data which limits the use of the computing resource. The licensing attribute certificate can also contain information allowing for the tracking of licensing data about the use of the computing resource. The use of a licensing attribute certificate to enforce access to a computing resource can allow products to be fielded which have their capability limited to a specific subset of functions. The enforcement data, the licensing data, and the data limiting the application to a specific subset of functions are cryptographically bound to the computing resource using a licensing attribute certificate according to the invention. Prior to allowing access to the computing resource by the computer application, a trusted computing base strongly authenticates that usage via the licensing attribute certificate.
