Scalable, highly available, dynamically reconfigurable cryptographic provider with quality-of-service control built from commodity backend providers

1. A method for embedding a handle of a module-centric commodity cryptographic service provider within a host-opaque region of a host-centric stateless application programming interface, comprising:

receiving the handle by a handle-oriented host library associated with the host-centric application programming interface;

transforming the handle into a hardware security module readable object by associating the handle with a host-resident key token of the handle-oriented host library to produce a transformed handle by the handle-oriented host library, the host-resident key token comprising host-opaque data, the transformed handle being associated with the host-opaque data;

selecting, in a stateless host library, a target hardware security module from a plurality of hardware security modules, in accordance with the transforming of the handle and based on object characteristics of the plurality of hardware security modules;

passing the transformed handle to module-centric stateful modules of the module-centric commodity cryptographic service provider, each module-centric stateful module including a wrapping key accessible by the target hardware security module of the stateless host library;

dispatching, by the module-centric commodity cryptographic service provider, the transformed handle to a virtualized handle in host token recovery of the stateless host library as a module identifier to a handle database, and to a stateless module having a master key;

retrieving a virtualized handle in the stateless host library;

de-serializing a serialized state of the handle in the target hardware security module based on the transforming of the handle into the hardware security module readable object;

restoring a serialized state of the target hardware security module by passing the handle back to a host token recovery of the stateless host library, wherein the serialized state is restored from the virtualized handle; and

wherein with respect to dispatching, by the module-centric commodity cryptographic service provider, the transformed handle, further comprising:

receiving the transformed handle by a commodity service provider dispatch of the module-centric stateful modules of the module-centric commodity cryptographic service provider;

dispatching the transformed handle by the commodity service provider dispatch to the stateless module.

2. The method of claim 1 , wherein the stateless host library includes an object store having several objects.

3. The method of claim 1 , further comprising:

passing the transformed handle as the virtualized handle to a handle database by the stateless host library;

passing the transformed handle to the module-centric stateful modules, each stateful module including a plurality of control keys, a plurality of data keys, and the wrapping key; and

passing the transformed handle to the host token recovery of the stateless host library, in preparation for the restoring of the serialized state.
