The world wonders
"The world wonders" is a phrase which rose to notoriety following
Encryption strategy
During World War 2, both basic and (for the time) sophisticated encryption ciphers were used. Some of these ciphers could be compromised through the recognition of predictable elements in the messages. For instance, messages might contain predictable intros or salutations such as "Dear" or "Sincerely". Today, this kind of vulnerability is known as a known-plaintext attack. At Bletchley Park, the Allies' codebreakers referred to these predictable elements as cribs, British schoolboy slang for a hidden cheat-sheet smuggled into a test or exam. Cribs, based on educated guesses about parts of the plaintext, were an invaluable part of the Allies' own code-breaking strategies.
To combat pattern recognition in encrypted messages, methods such as adding unique, non-relevant padding phrases were employed. For example, the US Navy during World War II might transform a simple message like "Halsey: Come home. - CINCPAC" into "Road less taken nn Halsey: Come home. - CINCPAC rr bacon and eggs" for encrypted transmission. The padding, marked by two-character words, was added before encoding and removed after decoding.
World War 2 was a pivotal period in the evolution of modern cryptography. While the ciphers of that era were vulnerable to techniques like known-plaintext attacks, the field has since advanced significantly, and modern ciphers are designed to be resistant to such vulnerabilities.
Background
On October 20, 1944, United States troops invaded the
Halsey, in command of the mobile naval forces covering the invasion's northern flank, fell for the ruse, and convinced that Northern Force constituted the main Japanese threat, proceeded northward in pursuit with the carriers of 3rd Fleet and a powerful force of battleships, designated Task Force 34. This left the landing beaches covered only by sixteen
Nimitz's message
When Nimitz, at
Where is, repeat, where is Task Force Thirty Four?
With the addition of metadata including routing and classification information, as well as the padding at the head and tail, the entire plaintext message to be encoded and transmitted to Halsey was:
TURKEY TROTS TO WATER GG FROM CINCPAC ACTION COM THIRD FLEET INFO COMINCH CTF SEVENTY-SEVEN X WHERE IS RPT WHERE IS TASK FORCE THIRTY FOUR RR THE WORLD WONDERS
[9]
While
Where is, repeat, where is Task Force Thirty Four? The world wonders.
The structure tagging (the 'RR's) should have made clear that the phrase was in fact padding. In all the ships and stations that received the message, only the decoder on Halsey's flagship, USS New Jersey, failed to delete both padding phrases.[13]
Consequences
The message (and its trailing padding) became infamous, and created some ill feeling, since it appeared to be a harsh criticism by Nimitz of Halsey's decision to pursue the decoy carriers and leave the landings uncovered. "I was stunned as if I had been struck in the face", Halsey later recalled. "The paper rattled in my hands, I snatched off my cap, threw it on the deck, and shouted something I am ashamed to remember", letting out an anguished sob.[14] RADM Robert Carney, Halsey's chief of staff (who had argued strongly in favor of pursuing the carriers), witnessed Halsey's emotional outburst and reportedly grabbed him by the shoulders and shook him, shouting, "Stop it! What the hell's the matter with you? Pull yourself together!" Recognizing his failure, Halsey ordered his fleet south, however the chase north had exhausted the fuel of his light escorts and more time was wasted refueling while Taffy 3 (Task Unit 77.4.3, commanded by Rear Admiral Clifton Sprague) was fighting for its life. Halsey returned to Samar with his two fastest battleships, three light cruisers and eight destroyers, but he arrived too late to have any impact on the battle.[15]
