Short Weather Cipher, the Glossary

The Short Weather Cipher (Wetterkurzschlüssel, abbreviated WKS), also known as the weather short signal book, was a cipher, presented as a codebook, that was used by the radio telegraphists aboard U-boats of the German Navy (Kriegsmarine) during World War II.^[1]

B-Dienst

The B-Dienst (Beobachtungsdienst, observation service), also called xB-Dienst, X-B-Dienst and χB-Dienst, was a Department of the German Naval Intelligence Service (Marinenachrichtendienst, MND III) of the OKM, that dealt with the interception and recording, decoding and analysis of the enemy, in particular British radio communications before and during World War II. Short Weather Cipher and b-Dienst are history of telecommunications in Germany.

Beaufort scale

The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land.

Cipher

In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure. Short Weather Cipher and cipher are cryptography.

Colin Grazier

Colin Grazier, GC (7 May 1920 – 30 October 1942) was a sailor in the Royal Navy who was posthumously awarded the George Cross for the "outstanding bravery and steadfast devotion to duty in the face of danger" which he displayed on 30 October 1942 in action in the eastern Mediterranean when capturing codebooks vital for the breaking of the German naval "Shark" Enigma cipher from the sinking.

Cryptanalysis

Cryptanalysis (from the Greek kryptós, "hidden", and analýein, "to analyze") refers to the process of analyzing information systems in order to understand hidden aspects of the systems.

Encryption

In cryptography, encryption is the process of transforming (more specifically, encoding) information in a way that, ideally, only authorized parties can decode. Short Weather Cipher and encryption are cryptography.

Enigma machine

The Enigma machine is a cipher device developed and used in the early- to mid-20th century to protect commercial, diplomatic, and military communication. Short Weather Cipher and Enigma machine are Signals intelligence of World War II and World War II military equipment of Germany.

Known-plaintext attack

The known-plaintext attack (KPA) is an attack model for cryptanalysis where the attacker has access to both the plaintext (called a crib) and its encrypted version (ciphertext).

Kriegsmarine

The Kriegsmarine was the navy of Nazi Germany from 1935 to 1945.

Kurzsignale

The Short Signal Code, also known as the Short Signal Book (Kurzsignalbuch), was a short code system used by the Kriegsmarine (German Navy) during World War II to minimize the transmission duration of messages.

Swell (ocean)

A swell, also sometimes referred to as ground swell, in the context of an ocean, sea or lake, is a series of mechanical waves that propagate along the interface between water and air under the predominating influence of gravity, and thus are often referred to as surface gravity waves.
