The present paper describes the development of the form, activities, and personnel of the cryptanalytical department of the military intelligence service of former Czechoslovakia in the context of the Cold War. The reconstruction of this branch of military intelligence describes the trends in its development as well as a number of problems faced, and results achieved. The paper demonstrates that successful deciphering of intercepted messages required high quality radio interception, highly qualified personnel, and modern IT technology. All of these conditions were met in Czechoslovakia, but to a varying degree depending on the period. Although the cryptanalytic department could boast with some successes in the pre-Second World War period, its development in the aftermath of the 1948 Communist coup was associated with declined efficiency. This situation lasted until mid 1950s, when the department enrolled young and qualified cadres. This development, together with the implementation of computer technology in early 1960s finally brought more significant successes in deciphering the encryption keys used by some NATO and Middle Eastern Countries. Since mid 1980s, the Czechoslovak military intelligence cryptanalysts faced challenges posed by significant changes in message transmission technology. Nonetheless, they managed to keep providing support to the tactical, operational and strategic levels of military command and significantly participated on the intelligence support of the Czechoslovak People’s Army and briefing of the Czechoslovak top state and party leaders.
