Abstract
A method, an apparatus, a system, and a computer program product is presented for virtualizing trusted platform modules within a data processing system. A virtual trusted platform module along with a virtual endorsement key is created within a physical trusted platform module within the data processing system using a platform signing key of the physical trusted platform module, thereby providing a transitive trust relationship between the virtual trusted platform module and the core root of trust for the trusted platform. The virtual trusted platform module can be uniquely associated with a partition in a partitionable runtime environment within the data processing system.
