Security communications interoperability protocol implementation

The Security Communications Interoperability Protocol (SCIP) is used to secure communications at military grade and is based on complex cryptographic operations. While many implementations exist, their structure was not made public because of the classified nature of the specifications. In recent years many aspects regarding the SCIP protocol have become publically available, making possible the presentation of partial or full implementations. The following paper describes a SCIP implementation that uses both hardware and software components in order to reduce development cost and increase design flexibility while respecting the algorithm timing constraints.
