Zoom Talk on Polish Cryptomachine LACIDA

Jerry McCarthy is a Volunteer Docent at The National Museum of Computing (TNMOC), Bletchley and an Occasional Speaker at the Piłsudski Institute, Hammersmith, London.

The talk will start with a brief description of the German 3-rotor Enigma and a summary of the various methods which Polish mathematicians and engineers created to decode messages sent by Enigma.

The talk will then move onto a Polish designed machine, the LACIDA, which has some similarities to Enigma, but also some major differences from Enigma. The two machines will be compared and contrasted and their relative advantages and disadvantages will be discussed.

The speaker will then demonstrate his software simulation; this will be followed by a Q&A session.
