摘要

摘要Truppenschlüssel（部队密码）是第二次世界大战期间德国军队使用的一种手动密码。基于一百多条在战争中幸存下来的真实信息，进行了密码分析。通过两个明文-密文折衷来研究精确的加密过程。利用爬山技术开发了一种专门的纯密文破解工具。这导致了大多数信息的成功中断。

Modern cryptanalysis of the Truppenschlüssel

Abstract Truppenschlüssel (troop cipher) was a manual cipher used by the German Army during World War II. Based on more than a hundred authentic messages that survived the war, a cryptanalysis is performed. The exact encryption procedure is investigated via two plaintext-ciphertext compromises. A specific ciphertext-only breaking tool is developed, utilizing the hill climbing technique. This leads to successful breaks of most of the messages.

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.
