Key-Tape Puncher
- this page is a stub
KTP-3 was a machine for the generation and duplication of random punched
paper key-tapes, developed in the late 1950s by
Standard Telefon og Kabelfabrik A/S (STK)
in Norway.
|
The machine was designed to create the key tapes for the
ETCRRM,
the SELMA
and the TCE-160.
It created two paper tapes simultaneously, and had provisions for verifying
the randomness of the generated cipher stream.
It is currently unknown how the random key stream was generated
(random or pseudo-random).
The image on the right shows a typical KTP-3 machine. At the front right are
two supply reels with blank paper tape. Once they are punched simultaneously
at the center, they are wound up on the two pick-up reels at the left.
