DA-8520 is a military
Electronic Messaging Unit (EMU) 1
with built-in encryption, developed by Nokia in Finland
for use with voice-grade radio and telephone equipment. In the Finnish Army
it is known as m/90 Sanomalaite, 2 abbreviated SANLA.
The device was later taken over by Patria Finavitec (later: Patria)
and sold as the M 85200 m/90.
From 1984 onwards, the device was also sold as a rebatched product
as the UA-8295,
albeit with an NSA-developed backdoor.
For user interaction, the device has a 55-button keyboard
and a 32-character red LED display.
Messages are encrypted with the
Data Encryption Standard (DES) in Output Feedback (OFB)
mode, and transmitted over narrowband radio channels
using Audio Frequency-Shift Keying (AFSK).
SANLA is the bigger version of the Nokia
Partiosanomalaite (PARSA) m/83
that was released in 1984. Together with the Keskussanomalaite
(KESANLA) these units were part of an integrated reconnaissance and command
messaging system (Sanomalaitejärestelmä) of the Finnish Army.
The device was developed in the second half of the 1970s and first released
to the Finnish Armed Forces in 1983. A year later, it was adopted by
Philips Usfa in The Netherlands,
for supply to both NATO and non-NATO members.
To non-NATO countries, Philips supplied the device – known as the
with a weakened encryption algorithm that had been provided by the
US National Security Agency (NSA)
as a drop-in replacement.
The same version, i.e. the Philips UA-8295,
was also sold by
MEL in the UK, as the BA-1402.
A weakened algorithm is also known as a
As the DES encryption algorithm should no longer be considered safe,
all SANLA and PARSA equipment in Finland was phased out in late 2013,
and was subsequently replaced by Panasonic CF-U1 Toughbook computers running
the Windows™ 7 operating system. Nevertheless, there are indications that
the Finnish Air Force still used PARSA
and SANLA devices as late as 2022 .
