3.3.6.2 HC-2413 Device
The HC-2413 device is manufactured by the Swiss company Crypto AG. As far
as can be seen from the photograph, it is based on the Sagem MC-850 phone, the
bottom part of which is modified by a scrambling device.
HC-2413 ensures full-duplex secure connection to similar devices as well as
landline phone terminals HC-2203 produced by the same company. The devices use
a 128-bit key and the custom algorithm designed by Crypto AG for encryption.
The use of such device helps protect conversations from tapping in any point of
transmission (of course, except for direct listening with super-sensitive microphones
placed in the immediate vicinity of the subscriber).
