FILL Saville ANT Siemens Bosch R&S KSP-1 →
The device is housed in a military green die-cast aluminium enclosure
that measures 135 x 64 x 38 mm and weights 342 grams (without battery).
Contrary to other key loading equipment, such as the
KYK-13
and the KSP-1,
the KLL-1 does not have an internal static memory to hold the key, but
transfers it directly from 8-level 2 paper tape to a crypto device (or a key
transfer device), just like the USA's
KOI-18 of which it is a clone.
A key tape is entered into the tape reader that is located under a hinged
lid, and should be pulled through the reader manually at regular speed.

The device is SAVILLE-compatible,
which means that it can be used with all crypto equipment
and key transfer devices that can handle the 128-bit 3
keys used by speech encryption devices
that feature the SAVILLE algorithm,
such as the KY-57,
KY-99,
Spendex 40
and the Elcrovox 1-4.
Such devices generally uses the
DS-102 protocol
in combination with a standard 6-pin U-229 socket
and a 1:1 transfer cable,
for transferring the keys.
When unloaded, the KLL-1 is unclassified [4].
Apart from ANT,
the KLL-1 was available under the Siemens,
Bosch,
Rohde & Schwarz
and other brand names.
The device is also known by its National Stock Number NSN 5810-12-314-6484.
In Germany, the KSP-1 is currently being replaced by the
Thales Data Transfer Device DTD-II
[5].

According to a Siemens brochure of 1991 [2],
the KLL-1 was developed by ANT in cooperation with
Siemens.
This is supported by the fact that the
custom chip inside the
device is made by Siemens.

8-bit ASCII data format, also known as IA No. 5
or ITA No. 5. ➤ More

SAVILLE is a secret cryptographic
algorithm, that was jointly developed by
GCHQ
and the NSA.
It uses an 120 bit secret KEY, with an 8-bit checksum.

The diagram below gives a quick overview of the features of the KLL-1
and demonstrates how it is used to transfer a SAVILLE key from
punched paper tape to a KSP-1 key transfer device. Once programmed, the
KSP-1 can be used to transfer the key to a cryptographic
device like a crypto telephone or a trunk encryption unit.
Instead of the KSP-1,
it is also possible to use the KYK-13.
Note that a transfer operation should always be initiated from the
host device. In the above case this means that it should be initiated
from the KSP-1 by pressing the START-button twice (once to turn it ON
and once to initiate the transfer), after which the key
tape should be pulled through the reader at a constant speed.
After a successful transfer, the letter 'P' appears in the display.

The interior of the DLL-1 can be reached by removing four
large bolts from the corners of the top panel, after which the
top panel can be removed.
The electronics are mounted on a
single PCB
that is mounted to the rear of the top panel.
The case shell only holds the
6-pin U-229 socket.
|
The image on the right shows the PCB mounted to the rear of the top panel.
The white section at the center of the PCB, is the actual
tape reader, that consists of eight thin spring contacts.
Apart from a single 20-pin custom LSI 1 chip, the PCB does not contain
any active components.
The board has two connectors: one for the 3.6V battery and one for the
wiring to the U-229 socket. In the image, the battery is connected
(via the red and black wires), whilst the U-229 wiring has been removed.
Note that the device does not contain any memory for key storage.

|
The battery is only used for powering the circuit (i.e. the custom
chip). The device is activated automatically when a tape is entered
into the reader. The clock pulses for the DS-102 transfer protocol
are generated by the holes in the key tape when
pulling the tape through.
