The Headline Puzzle is a monthly feature that was started in 1964 by Paul Derthick, a longtime research analyst in NSA’s Operations Organization, as an interesting way to keep his mind sharp outside of his cryptanalytic work. Each Headline Puzzle contains five headlines from recent daily newspapers. Each of the five is a different monoalphabetic substitution, and all five are derived from the same mixed alphabet at different settings against itself. A complete solution includes recovering the plaintext of each HEADLINE and three key words, the SETTING, the KEY and the HAT.
To see an example of a previous Headline Puzzle from August, click here for the Encrypted Headlines, here for the Decrypted Headlines, and here for the SETTING, the HAT, and the KEY. Visit NSA.gov/Puzzles to learn more about this and other cryptologic challenges from NSA's puzzling community.
