“…43 Perhaps the original contained an error, and its authors really meant ''similar OTPs.'' The Poles were aware of the possibility of such decrypts, as evidenced by [25]. 44 This cryptic term probably denotes copies of the keying patterns or the OTPs.…”

“…In that time, the Poles were preoccupied with the possibility of electro-magnetic emanation interception attacks by their adversaries and tested the cryptographic equipment to protect it. 25 The Cyklamen sets were used to generate one-time pads for manual encryption. They used the GZL (Generator Znakow Losowych, literally, random number generator) modules with a selected Zener Diode as a source of entropy.…”

This article is an attempt to assess the broad scope of communist Polish code breaking during the middle and late periods of the Cold War. Based on the recently released documents available now at the Polish Institute of National Remembrance, it portrays the 'civilian' intelligence codebreaking section's achievements and challenges, particularly between 1959 and 1989. The text suggests numerous successes of communist Polish codebreakers in defeating cryptosystems used by various European and non-European countries, particularly the Hagelin CX-52, and details the possible methods and tools utilized by Cold War Poles that facilitated the exploits. It proves that even a country with limited resources from behind the Iron Curtain can easily defeat strong cryptography.
