Announcing the Herky Crypto Challenge - 2

I am pleased to announce the second Herky Crypto Challenge.

As you may recall, back in 2013 I created the first Herky Crypto Challenge. The Challenge consisted of several problems in cryptography that needed to be solved to complete the challenge. It took two years, but ultimately several groups of undergraduate Computer Science students completed the challenge and a medallion was awarded at the 2015 Student Awards Banquet. Many ECE students also worked on the challenge.

As noted above, I have created Herky Crypto Challenge - 2. Although similar to the first Challenge, this one has a new set of problems that highlight a variety of cryptanalysis techniques on various cryptographic technologies and includes several problems relevant to modern network security. It also contains problems of historical importance.

The following puzzle contains information on how to begin the challenge:

With the large influx of Computer Science and Engineering students, I am looking forward to some of our best and brightest completing the challenge!
