INDICTOR
COMSEC module - this page is a stub

INDICTOR is an embedded COMSEC module, developed by the US National Security Agency (NSA), that povides encryption of voice and low speed data signals. It support a range of existing voice coding schemes and uses the highly secret GCHQ/NSA-developed SAVILLE encryption algorithm.

The unit operates from a single 5V DC power supply with low power requirements and can be keyed remotely by existing re-keying techniques. It supports many voice coding schemes, such as CVSD, LPC, RELP and PCM. It is compatible with KY-57 and KY-58, Vinson AN/CSZ-1 and KYV-2 at 12 an 16 kbit/s. A half-duplex module operates with ANDVT and STU-III/MPT at 2400 baud. According to public sources, INDICTOR supports SAVILLE I, PADSTONE and CORDOBA (Type 2).

The manufacturer is currently unknown.
