Secure Communications Interoperability Protocol
SCIP is a standard for secure voice and data communication, developed by the
Digital Voice Processor Consortium (DDVPC) of the US Department of Defense
in cooperation with the National Security Agency (NSA).
SCIP is based on the US Government's earlier Future Narrowband Digital
Terminal (FNBDT) project, and is platform-independant as it makes no
assumptions about the underlying hardware.
The first SCIP devices were used in the US in 2001 (FNBDT).

The major success of SCIP however, came after the US decided to share the
SCIP technology with a number of other nations in 2003. Since then, a wide
range of SCIP-compatible devices have been developed in various countries.
SCIP supports different modes of operation, including national (US) and
multi-national modes with different types of encryption.
SCIP can be used over a variety of communcation systems, such as PSTN
telephone lines, ISDN, radio links, satellites, cellular phones
and internet (Voice over IP). It was designed to make no assumptions about
the underlying hardware. The only requirement is a minimum
bandwidth of 2400 Hz. Once a SCIP device connects to another SCIP device,
they first negiotiate the parameters and then choose the best possible
mode of operation.

By migrating to SCIP, all systems for secure communication used by the US
Government will eventually be compatible, which was not the case in the
past when different systems were used. In 2006, an upgrade for
Secure Teminal Equipment (STE) was released,
making the STE compatible with SCIP.
The older STU-III secure phones can not be made SCIP
compatible and have therefore been phased out in 2009.
A good desciption of SCIP can be found on Wikipedia [1].
