X.25 Data encryptor
- this page is a stub
PPSX was a
digital encryption device
for public and private X.25 data networks, developed around 1990 by
Philips Crypto BV (Usfa) in Eindhoven (Netherlands). The
device was intended for secure payment transactions via X.25 lines
and for the connections between terminals and mainframes.
|
The PPSX 2060 series was introduced around 1990, with the PPSX 2065 being
the first one to be released. It was housed in the same enclosure as the
PFDX fax encryptor – shown in the image on the right –
and used the same proprietary Philips Crypto Heart as the
fax encryptor (PFDX)
and the PNVX secure telephone of the same era.
At least two different versions are known to have existed: the PPSX-2065
(visible on the right) and the PPSX-2061, which was housed in a smaller
case. The difference between the two versions is currently unknown, but
might be price-related.

- PPSX-2061
This version is housed in a slimline plastic enclosure and was probably
release around 1994, as a cheaper alternative for the PPSX-2065 below.
- PPSX-2065
Initial version of the X.25 data encryptor, housed in the same enclosure
as the PNVX fax encryptor. This version was probably
released in 1990.
- PPSX-6361
This is Dutch Government version of the PPSX-2061. It is bascially the same
device, but is equipped with a Crypto Heart that is based on the ultra-secure
OQ-4436 Crypto Chip, rather than the
less secure OQ-4434.
