EE 418 : Handout # 2

This lecture presents Euclidean algorithm, and then introduces Vigenère, Hill, permutation and stream ciphers. We define attack models for performing cryptanalysis on different ciphers, and show how statistical analysis of the English language can be used to cryptanalyze cryptosystems with large key spaces. Readings from Chapter 1 of D. Stinson. 1 The Euclidean Algorithm(s) Many of the crypto s...

EE 126 : Problem Set # 2 - Solutions Instructor

Problem 1a. Ω = {T,H} b. Let set A = {1, 2, 3, ..., N} be the set of N balls numbered 1 to N. We have two choices for Ω. In the first choice, an outcome specifies which ball was picked first and which was picked second. With this choice, Ω = Ω1 := {(x, y) | x, y ∈ A, x 6= y}. In the second choice, an outcome only specifies the two balls that were picked, but not their order. With this choice, Ω...
