FLEXIBLE SECURE DATA COMMUNICATIONS WITH THE RANGE ENCRYPTION MODULE

Abstract

This paper discusses the design, application and flexibility of the Range Encryption Module (REM) developed by L3 Communications Conic Division for the Range Application Joint Program Office (RAJPO) located at Eglin Air Force Base in Florida. The REM is a burst encrypter that utilizes the National Security Agency Thornton CTIC/DS- 101 Hybrid (CDH) encryption algorithm. The CDH device operates under the control of a Conic-designed digital ASIC. The CDH, ASIC, Power Management and parallel bus interface circuits reside on a single card within the REM called the Common Encryption Core (CEC). The REM and CEC card within the REM offer flexibility in many operational features, as described below.
