Abstract

Slovakia was an allied (puppet) state of Germany during WW2. In various Slo-vak and Czech archives, we found pre-viously unknown details about diplomatic ciphers used by the Ministry of Foreign Affairs during WW2 in Slovakia. Here we present cipher systems used by Slovak At-tache´ and give insight into the encryption problems of the Ministry and embassies.
