#### Course Catalogue Description

Historical Introduction to Cryptography: General Principles, Monographic-Polygraphic Systems, Monoalphabetic-Polyalphabetic Systems, Substitution Ciphers, Transposition Ciphers, Frequency Analysis, Kasiski Analysis. Shannon's Theory: Perfect Secrecy, Entropy. Cryptographic Evaluation Criteria and Cryptanalysis. Public and Private Key Cryptography. Block Ciphers: Diffusion, Confusion, Feistel Structure. Stream Ciphers: Shift Registers, Synchronous and Self-synchronous Ciphers, Linear Complexity. Public Key Cryptography: Fundamental Concepts, NP-Hard Problems, Discrete Logarithm, Factorization, Subset Sum, RSA, Diffie Hellman Key Exchange Protocol, DSA, Cryptographic Protocols.#### Course Objectives

The aim of this course is to give the fundamental concepts of cryptography and introduce to students the classical private-key and public key cryptographic systems. The course also serves as an introduction for students who are interested in persuing research in cryptography.#### Course Learning Outcomes

This is one of the core courses of the Cryptography Program at IAM, which gives the fundamentals of cryptography and the classical private-key and public-key cryptographic systems. After taking the course, the students should have an overview of some of the classical cryptosystems, which are in use.#### Tentative (Weekly) Outline
