Key Recovery Functional Model

Abstract

This document describes a model for key recovery. The means by which plaintext may be recovered or reconstructed from recovered key(s) is not addressed in the key recovery model. The key recovery model is a generalized model that encompasses a wide variety of key recovery systems, including both key backup and encapsulated key recovery information techniques. The key recovery model is a functional model. That is, the components of the model are functional components not system components.
