Defense Message System

The Defense Message System or Defense Messaging System (DMS ) is a system for secure email and directory service with the U.S. Department of Defense. DMS was introduced around the AUTODIN network to replace and is based on implementations of the OSI X.400 mail standards, X.500 directory services and X.509 public-key certificates with many extensions to the special requirements for a military communications system. meet DMS is sometimes used in conjunction with third-party products, such as the DMDS ( Defense Message Dissemination System ) of the U.S. Navy, assumes that messages based on certain criteria and forwards them to the places from which expects a response to the message will. This combination has had, especially in the upper levels of command great success, since the forces no longer have to wait for placement personnel will route the message manually to the right participants. The Navy also used the Navy Regional Enterprise Messaging System ( NREMS ). NREMS AMHS uses a backend to secure organizational messages via a web interface to the Naval commands to send.

The DMS version of the U.S. Army runs for both CONUS as well as areas outside the USA on an AMHS platform. The Pentagon Telecommunications Center (PTC ) is the distribution point for CONUS operations, in addition there are various AMHS installations for strategic messaging OCONUS ( outside the U.S.). In the tactical environment of the U.S. Army also exists the independent Tactical Message System ( TMS), which also builds on an AMHS platform and is intended to provide secure exchange of messages in the event that AMHS OCONUS installations are unreachable.

The DMS is coordinated by the Defense Information Systems Agency ( DISA ). Testing began in 1995. For operation DMS relies on many third-party products such as DMDS, DMDS proxy MR, CP- XP ( the CommPower XML Portal), AMHS (Automated Message Handling System), MMHS (Military Message Handling System) and CMS 1.0.
