FRAMEWORK-BASED CRYPTOGRAPHIC KEY RECOVERY SYSTEM

A Secure Key Management Framework (SKMF) defines an infrastructure for a complete set of cryptographic services augmented with key recovery enablement. There are three major layers—the application layer invokes the SKMF layer, while the SKMF layer invokes the service provider (SP) layer. The application layer code invokes the cryptographic API and key-recovery API supported by the SKMF. Multiple key recovery mechanisms and cryptographic mechanisms can be implemented as service providers that log-in underneath the framework using the well-defined service provider interfaces provided by the framework. The SKMF implements the supported ATP calls by making appropriate invocations of the service provider modules using the SPIs.
