Abstract

A cryptographic framework consists of four basic service elements that include a national flag card, a cryptographic unit, a host system, and a network security server. Three of the four service elements have a fundamentally hierarchical relationship. The National Flag Card (NFC) is installed into the Cryptographic Unit (CU) which, in turn, is installed into a Host System (HS). Cryptographic functions on the Host System cannot be executed without a Cryptographic Unit, which itself requires the presence of a valid National Flag Card before it's services are available. The fourth service element, a Network Security Server (NSS), can provide a range of different security services including verification of the other three service elements. The framework addresses national policies governing cryptography, where such policies can be independently developed and maintained using a such a framework. Furthermore, the common service elements provide the necessary focus for establishing interoperability while reconciling these different National policies.
