Crypto FILL Philips UP-2001 → UP-2101 →
Net Key Program
UP-2002 (or PKMX-2002) was a software-based Key Management System (KMS),
consisting of a software program running on a DOS PC, developed by
Philips Usfa BV in 1988. It was used to create 128-bit
keys for cryptographic devices such as the Spendex 40,
the Spendex 50
and the Aroflex.
Such keys consist of 120 key bits, plus an automatically calculated
8-bit checksum appended at the end. The UP2002 program was used for a
variety of applications and devices.
The image above shows a screen shot of the main main of the UP-2002
Net Key Program. The program can be used to generate random keys,
based on the Real Time Clock (RTC) and a seed variable entered by the
user, and automatically calculates the 8-bit checksum. It also allows
the user to enter an externally generated key manually, with or without
checksum (or: parity).
Keys are usually loaded into a key transfer device,
such as the Philips UP-2001
or the UP-2101, via the serial (RS-232) port.
Alternatively, keys can be printed onto paper as a Type-39 barcode.
This barcode can then be read by means of an HP HBVR-8300
barcode reader connected to an UP-2001.
This allows the keys to be sent by courier or by secure fax
(e.g. via a Spendex 40).
Barcodes can be printed by the UP-2002 software to any EPSON or
IBM-compatible printer.

Over time, the UP-2002 software has confusingly been given various names,
such as PKMX-2002 and CKMS.
On this page, the generic name UP-2002 is used.
Furthermore, different versions of the software (and the generated keys)
were released for different projects and custormers.
