# Classical Cryptosystems and Core Concepts (Coursera)

## Descripción de “Classical Cryptosystems and Core Concepts (Coursera)”

Welcome to Introduction to Applied Cryptography. Cryptography is an essential component of cybersecurity. The need to protect sensitive information and ensure the integrity of industrial control processes has placed a premium on cybersecurity skills in today’s information technology market.

Demand for cybersecurity jobs is expected to rise 6 million globally by 2019, with a projected shortfall of 1.5 million, according to Symantec, the world’s largest security software vendor. According to Forbes, the cybersecurity market is expected to grow from \$75 billion in 2015 to \$170 billion by 2020. In this specialization, you will learn basic security issues in computer communications, classical cryptographic algorithms, symmetric-key cryptography, public-key cryptography, authentication, and digital signatures. These topics should prove especially useful to you if you are new to cybersecurity Course 1, Classical Cryptosystems, introduces you to basic concepts and terminology related to cryptography and cryptanalysis. It is recommended that you have a basic knowledge of computer science and basic math skills such as algebra and probability.

Who is this class for: Learners with CS experience or education looking to:

○ Enhance/refresh critical skills;

○ Seeking to expand their opportunities. Learners undecided about pursuing a bachelor’s degree;

○ Seeking professional credit that may be applied towards a bachelor’s degree.

Course 1 of 4 in the Introduction to Applied Cryptography Specialization

### Syllabus

WEEK 1

Specialization Introduction

This module covers an introduction of the specialization and instructors, covers what to expect from this educational experience and also, an introduction to the course Classical Cryptosystems and Core Concepts.

Cryptographic Tidbits

In this module we present an introduction to cryptography, differentiate between codes and ciphers, describe cryptanalysis, and identify the guiding principles of modern cryptography. After completing this course you will be able to read material related to cryptographic systems, understanding the basic terminology and concepts. You will also have an appreciation for the historical framework of modern cryptography and the difficulty of achieving its aims.

WEEK 2

Cryptanalysis

Delving deeper into cryptanalysis, in this module we will discuss different types of attacks, explain frequency analysis and different use cases, explain the significance of polyalphabetical ciphers, and discuss the Vigenere Cipher. When you have completed this module, you will have an appreciation of the different types of attacks and under what kinds of situations each might be applicable.

WEEK 3

Hash Functions

Continuing on our exploration of the fundamental concept of cryptography, this module will explain the Hash Function, its purpose and application, potential attack vectors, and the importance of hash functions on cryptographic design. Upon completion you will be able to understand the role that hash functions play in cryptography and how cryptographic hash functions differ from other types of hash functions.
