An untrusted component exposing a high level storage object interface within an untrusted client virtual machine accepts application level storage object operations. Responsive to a storage object operation, the untrusted component passes a message through the underlying hypervisor to an associated trusted component. The trusted component processes the message by authenticating the client virtual machine and locating an internal mapping between the client virtual machine and an associated customer-specific set of backend storage resources to which the requested storage object operation is to be applied. The trusted component uses a trust relationship with the backend storage system to securely communicate the storage object operation to the backend storage system, and passes the operation results through the hypervisor back to the untrusted component in the source client virtual machine from which the storage object request originated.

An encryption management system provides a solution for embedded system device authentication, secure server-to-device communications, and encryption key management. It reduces implementation times and costs associated with using cryptography for authentication and data privacy with embedded systems applications by freeing application developers from having to develop, manage, or update security-based features in their server-based applications. The template-based approach of the system provides highly customable and accessible security functionalities. To utilize services provided by the encryption management system in some embodiments, calling applications provide input parameters and function calls in the form of a template at runtime, and the output in the form of encrypted and secured messages are either sent to the client devices automatically or returned to the calling applications. As such, security functionalities and objects, though segregated in the encryption management system to provide enhanced protection, can still be easily accessed and can be updated without recompiling the calling applications.
