Abstract
A technique to provide a hardware security module that provides a secure boundary for retention of a secure key within the secure boundary and prevention of unauthorized accesses from external sources outside of the secure boundary to obtain the secure key. The hardware security module includes a security processor to unwrap and authenticate a secure key within the secure boundary to decrypt or encrypt data and to provide data through a single interface that communicates with external sources, so that all data transfers between the secure boundary, formed by the hardware security module, and external sources are transferred only through the interface. The hardware security module ensures no unwrapped key leaves the secure boundary established by the hardware security module.
