Spread Spectrum Communications
Authors: Hedy Lamarr and George Antheil (United States)
Creation date: 1941
Function: During World War II, actress Hedy Lamarr and composer George Antheil invented a communication system called "spread spectrum." Their goal was to develop a technology that would make it difficult for the enemy to track and interfere with communications. The spread spectrum system used a pseudo-random sequence to transmit and receive signals, making it challenging to detect and decipher for enemies.

Comparison between the inventions:
Function: The cryptanalysis of the Lorenz machine focused on decrypting encrypted messages generated by the German Lorenz machine, while spread spectrum communications aimed to protect transmissions by using a pseudo-random sequence to make it difficult to detect and decipher signals.
Authors: The cryptanalysis of the Lorenz machine was primarily carried out by Bill Tutte, a British cryptanalyst. On the other hand, spread spectrum communications were developed by Hedy Lamarr, an Austrian actress, and George Antheil, an American composer.
Approach: The cryptanalysis of the Lorenz machine focused on decrypting enemy messages to gather information about German plans and movements. Spread spectrum communications, on the other hand, aimed to protect one's own transmissions to prevent interception and understanding by the enemy.
Technology used: The cryptanalysis of the Lorenz machine relied on analyzing the patterns and structure of the Lorenz machine. Spread spectrum communications made use of a pseudo-random sequence to transmit signals and make it difficult to detect.
Impact on the war: The cryptanalysis of the Lorenz machine was crucial for the Allies to gather valuable information about German operations and plans. On the other hand, spread spectrum communications, although innovative, did not have a direct impact on the war's outcome.
Cryptanalysis of the Lorenz machine
Author: Bill Tutte (United Kingdom)
Creation date: 1942
Function: The cryptanalysis of the Lorenz machine involved decrypting the encrypted messages generated by the Lorenz machine, used by the Germans for high-level communications. Bill Tutte, a British cryptanalyst, managed to understand the patterns and structure of the Lorenz machine, which allowed the Allies to read and decipher enemy messages.
