Electronic Key Management System - Reasons For Development

Reasons For Development

The primary reason for the development of EKMS centers on the security and logistics problems that plagued the COMSEC Material Control System (CMCS), which replaced the Registered Publications System (RPS) in the 1970s. The CMCS was a very labor-intensive operation that had been stretched to capacity. The most serious, immediate concern was the human threat associated with access to and exploitation of paper key throughout its life cycle. The disclosure of the Walker spy ring was clear justification of this concern. Although eliminating the majority of paper keys will greatly reduce this human threat, the long-term goal of EKMS to minimize human access to keys will not be realized until benign fill key is fully implemented. Benign fill permits the encrypted distribution of electronic keying material directly to the COMSEC device without human access to the key itself.

The need for joint interoperability led to the Defense Reorganization Act of 1986, under which the Joint Chiefs of Staff (JCS) tasked NSA, the Defense Information Systems Agency (DISA), and the Joint Tactical Command, Control and Communications Agency (JTC3A) to develop a Key Management Goal Architecture (KMGA). Subsequent difficulties in coordinating COMSEC distribution and support during joint military operations, e.g., Desert Storm, Urgent Fury, and Operation Just Cause, have further emphasized the need for a system capable of interoperability between the Services.
