Towards Quantum Enigma Cipher II-A protocol based on quantum illumination-

This research note II introduces a way to understand a basic concept of the quantum enigma cipher. The conventional cipher is designed by a mathematical algorithm and its security is evaluated by the complexity of the algorithm in security analysis and ability of computers. This kind of cipher can be decrypted with probability one in principle by the Brute force attack in which an eavesdropper ...

The Cryptanalysis of the Enigma Cipher . The Catalogue Method

The catalogue algorithm given below can be used to decode messages eavesdropped before September 15, 1938, because that day the German service changed the manner of announcing message settings. The algorithm is a reconstruction and a completion of the catalogue method (invented by Rejewski). Historians described the idea of the method and omitted details. The author tested the behavior of the c...

On Rejewski’s Solution of Enigma Cipher

In this contribution I want to present the extract of the article about Rejewski’s solution of Enigma cipher, which is being prepared. The story of Enigma is a part of modern cryptology. However, there still remain some unclear facts about Enigma. The reason is that the information were for a long time classified, now there is a lack of reliable sources. Moreover, some of the reports are even c...

The Swiss NEMA Cipher Machine

The Enigma is probably the most well known wired wheel cipher machine. The NEMA is a cipher machine developed during World War II by the Swiss Army. It is designed on the same principle as the Enigma but with particular emphasis on overcoming some of its weak features. It was declassified by the Swiss Authorities in 1992. This paper describes its mechanism and the way in which it operates, so t...
