in class, we discussed using frequency analysis patterns to identify letter signatures, and how to use that information to make potential plaintext-to-ciphertext mappings. In particular, we focused on the letters t, h, e. What are the frequency patterns used to identify English plaintext t, h, e? What ciphertext letters did you choose to correspond to plaintext t, h, e, and why did you make those choices?

Discuss other uses of frequency analysis to identify letter signatures (besides the letters t, h, e), and how you used that to make potential plaintext-to-ciphertext mapping. Describe as much frequency analysis as necessary until you can transition to wordspotting, but at least enough to show how you identified two other letters (see solutions to MA practice cryptanalysis for examples).

Wordspotting

Give an example of wordspotting in your cryptanalysis solution. What was the partial text, and what word/phrase completion did you guess?

5 Give second, different example of wordspotting

Filling in alphabetic portion of key

Alternate makeup - If you attempted to fill in the alphabetic portion of the key, what letters did you choose to fill in where? Explain the reasoning behind your choices
