Collaboration and Collation: Breaking German diplomatic ciphers in 1942
(Tartu University Library, 2026-06-22) Turing, Dermot; Desenclos, Camille; Pierrot, Cécile
German diplomatic signals enciphered in the Floradora double-additive system were broken at the end of 1942 as a result of Anglo-American collaboration. The American contribution was a novel and ingenious system of machine search for likely additive combinations, which allowed the choice of additives to be revealed. The paper suggests a reconstruction of the machine methodology, which used punched-card sorting and collation.

Cryptology and redaction – a strange symbiosis
(Tartu University Library, 2024) Turing, Dermot; Waldispühl, Michelle; Megyesi, Beáta
This paper explores the relationship between cryptology and redaction. Redaction can be a frustration to historical cryptology research. Examples of redactions of historical papers relevant to cryptology are presented. It is concluded that the practice of redaction is often ineffective and the policy rationale behind redactions difficult to understand.
