Kryptos 2019  Results

[preliminary]

One hundred and forty nine students formed 62 teams representing colleges, universities, and high schools from France, Idaho, Illonois, Massachusetts, New York, North Carolina, Oregon, Pennslyvania, South Carolina, Vermont, Virginia, Washington, and Wisconsin.

Our first place finisher solved the first Challenge within six minutes and completed all three Challenges in just under three and a half hours.  Thirty-six teams finished at least one of the Challenges and 15 completed all three.  The Kryptos CodeMasters appreciate all the hard work teams and individuals put into working on these challenging ciphers.

Those teams which submitted at least one correct solution are recognized below. The order of the listings indicates the chronological order of when the solutions were submitted.

Congratulations to all!

κρυπτοσ or kryptos, is a contest open to any and all undergraduate students. The theme of the contest is centered around the breaking, or cryptanalysis, of ciphers (secret writing). Each challenge presents contestants with a brief scenario together with some ciphertext (encoded message). The goal is to discover the original English plaintext message!

Clues to help break the cipher may be contained in the actual ciphertext or in the details of the accompanying scenario.

While it is not the intent of this contest to test overly technical aspects of crypanalysis or advanced mathematical algorithms, some familiarity with basic codemaking and codebreaking is certainly helpful. Some useful sources include:

• Challenges from previous competitions.
• The American Cryptogram Association.
• Wikipedia entries for Cryptography and Cryptanalysis.
• The Code Book by Simon Singh.
• Codes and Ciphers by R.F. Churchhouse.
• Codes, Ciphers and Secret Writing by Martin Gardner.
• Secret History: The Story of Cryptology by Craig Bauer
• Slides from a recent PNW-MAA minicourse.

Contestants should also be aware that there are quite a few freely available programs and applets that may aid in some of the more tedious aspects of code breaking (e.g. frequency analysis). However, keep in mind that there are never any guarantees with such software!

To Participate

Individual undergraduate students, or teams of up to three, are eligible to participate. Each individual or team must have a faculty sponsor in order to register.

Please read the official contest rules and instructions for submitting solutions before the contest begins.

When the contest begins at 4 p.m. PDT on April 4, 2019, the Cipher Challenges will be available at this website. Begin working and have fun! Solutions need to be submitted by 4 p.m. April 8, 2019. All times are Pacific Daylight Time.

Results will be posted here shortly after the end of the contest. As teams finish each challenge, please prepare and submit solutions according to the guidelines.

Please submit your solutions as you solve each challenge as the time taken to solve a challenge will be used to determine final rankings.
