Suppose S1 is the Shift Cipher (with equiprobable keys, asusual) and S2 is the Shift Cipher where keys are chosen withrespect to some probability distribution pK (which need not beequiprobable). Prove that S1 X S2 = S1.

The Date Shift cipher is a much harder code to break than, for example, the more simple Shift cipher. This is because the shift number varies from letter to letter, and also because it’s polyalphabetic (this means that a single number can represent multiple letters). I’ll explain it all in the video. If you've got KIDS AT HOME, I can do all the teaching for you so you can take a break! Go here for more hands-on math and science lessons: www.SuperchargedScience.com/school | Supercharged Science a
