Universally Composable Key-Management

Abstract : We present the first key-management functionality in the Universal Composability (UC) framework. It allows the enforcement of a wide range of security policies and can be extended by diverse key usage operations with no need to repeat the security proof. We illustrate its use by proving an implementation of a Security API secure with respect to arbitrary key-usage operations and explore a proof technique that allows the storage of cryptographic keys externally, a novel development in the UC framework.
