The 6th annual Cryptorally is a cipher-solving competition for those interested in cryptology. The Cryptorally competition is open to all students, but requires online registration.
Registration to run the rally is closed.
The featured lecture and poster session are free and open to everyone.
At 10:00a.m., each team of students will be given its first cipher to solve. The answer to that cipher will lead to a specific location on campus where the team will receive its next cipher. The competition is similar to a scavenger hunt. Clues will lead each team across campus to various secret locations, and ultimately to the final location. The first team to solve all the ciphers correctly and arrive at the final location will be the winner and receive a special prize. Prizes will be awarded to first, second, and third place teams in each of the two divisions.
There are two divisions of competition:
Middle school or junior high school students
Professor of Mathematics
Arizona State University
Cards and LFSRs
We will demonstrate a math-based card trick. Explaining how it works will lead us to a type of cipher called a Linear Feedback Shift Register.

The School of Mathematical and Statistical Sciences has hosted the Cryptorally event for the past five years. The Cryptorally is designed by Nancy Childress, associate professor who teaches cryptography.
Cryptography, the science of making and breaking codes and ciphers, is an important field of study today. Cryptography helps to protect personal, financial, proprietary and defense-related information. Among many other things, it is used in internet commerce and in communication devices, such as mobile phones and cable boxes. Modern cryptology relies on ideas from number theory, abstract algebra and discrete mathematics. A good background in these subjects is essential for anyone who wants to understand how modern cryptosystems work.
