Abstract
A mechanism is provided for securing cryptographic functionality within a host system such that it may only be used when a system administrator physically allows it via a hardware security token. In addition, a hardware security unit is integrated into a data processing system, and the hardware security unit acts as a hardware certificate authority. The hardware security unit may be viewed as supporting a trust hierarchy or trust framework within a distributed data processing system. The hardware security unit can sign software that is installed on the machine that contains the hardware security unit. Server processes that use the signed software that is run on the machine can establish mutual trust relationships with the hardware security unit and amongst the other server processes based on their common trust of the hardware security unit.
