Abstract

Abstract The Štolba cipher machine was the first Czechoslovak cipher machine used in the army after the mid-1930s, and later in Slovakia during WW2. It had a unique design based on pneumatic transmission and complex stepping rules. We present basic facts about the Štolba machine from documents found in Czech and Slovak archives. Although the machine description was incomplete (and in some cases not accurate), we have been able to reconstruct (a highly probable) encryption algorithm, and develop a method to reconstruct (message) key from a known PC pair. Part of the machine configuration, however, still remains unknown due to the large space of possible settings and the complexity of the algorithm.

捷克斯洛伐克第一台密码机

Štolba密码机是20世纪30年代中期后捷克斯洛伐克军队使用的第一台密码机，后来在二战期间在斯洛伐克使用。它具有基于气动传动和复杂步进规则的独特设计。我们从捷克和斯洛伐克档案中发现的文件中介绍了关于Štolba机器的基本事实。尽管机器描述不完整（在某些情况下不准确），但我们已经能够重建（一种极有可能的）加密算法，并开发出一种从已知的PC对重建（消息）密钥的方法。然而，由于可能的设置空间大和算法的复杂性，部分机器配置仍然未知。

期刊介绍： Cryptologia is the only scholarly journal in the world dealing with the history, the technology, and the effect of the most important form of intelligence in the world today - communications intelligence. It fosters the study of all aspects of cryptology -- technical as well as historical and cultural. The journal"s articles have broken many new paths in intelligence history. They have told for the first time how a special agency prepared information from codebreaking for President Roosevelt, have described the ciphers of Lewis Carroll, revealed details of Hermann Goering"s wiretapping agency, published memoirs - written for it -- of some World War II American codebreakers, disclosed how American codebreaking affected the structure of the United Nations.
