Objectives and Content

Objectives and Content:

The course gives an introduction to cryptanalysis. Roughly, the goal of cryptanalysis is given a siffer-text find the plain-text. Basic cryptanalytic attacks against symmetric ciphers are introduced.

Content:

The course contains three chapters. The historical ciphers chapter deals with analysis of various substitution and transposition ciphers, Hagelin cipher, and Geheimschreiber. The stream ciphers part contains time-memory trade-offs, attacks based on Berlekamp-Massey algorithm, correlation and algebraic attacks, 2-adic cryptanalysis. The block cipher chapter explains meet-in-the-middle attacks and linear and differential cryptanalysis.
