Secure two-way mobile radio · CRYPTOVOX

SE-580, was a semi-portable two-way radio for
voice communication with high-end encryption,
made in the early 1990s by
Crypto AG (Hagelin) in Zug (Switzerland) as part of the
Cryptocom® family.
It is based on the Nokia Mobira 1
RD-58 radio set,
and features the HC-3400 encryption engine.
It was also available as the CSE-580,
which is the same radio, with a different handset.

The Nokia Mobira RD-58
was a versatile radio with a high output power (18W)
that was used for mobile and semi-portable communication in the UHF band
(around 440 MHz), especially in situations were the distance to another
mobile station or to a base station was relatively large.
For this reason, the RD-58
was a popular device for the analogue mobile
telephone networks of the 1980s, such as the
NMT-450 2 network.
It was also used as a two-way FM radio in many trunking radio networks,
and was converted for secure voice communications by Crypto AG.

This was done by integrating Crypto AG's highly acclaimed HC-3400 crypto
engine into the radio, just like this was done with Ascom's
SE-160 handheld radio
(also available from Crypto AG) and the
SE-660 mobile radio.
The HC-3400 was implemented as a single-chip
solution and required the KED-3400 key entry device
for loading the cryptographic KEYs into the crypto engine.

The Nokia Mobira was made for a wide variety of applications and was
available in many different versions and variants. It was sold as a
mobile telehone, as a two-way radio, and as a trunking radio.
-
NMT-450 was known in the Netherlands as
ATF-2.
|
For loading cryptographic KEYs into the HC-3400 crypto engine of the
SE-580, the Hagelin KED-3400 key entry device was used.
The KEYs are 128 bits long and can be generated manually (entered via the
keyboard) or generated automatically using the internal random number
generator (RNG).
The device supports the so-called 3-KEY strategy.
