Curso 1 de 4 em Specialization Introduction to Applied Cryptography

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.

Greetings and

welcome to the specialization on the introduction to applied cryptography.

My name is WIlliam Bond and I'm an Instructor of computer science

at the University of Colorado, Colorado Springs.

Like many folks my age,

I came to the field of information assurance along a highly nonlinear path.

Most of my professional career has been designing full custom integrated circuits,

but I became involved in the palm of jam resisted communication without shared

secrets while I was teaching at the US Air Force Academy and

that became the focus of my PhD work, albeit in electrical engineering.

As part of that research, I became rather immersed in the field of cryptography and

haven't looked back yet.

>> And my name is Sanyong Cheng and I'm an Assistant Professor also at the computer

science department at UCCS, University of Colorado, Colorado Springs.

I research in computer security and computer network with focuses on wireless,

and embedded systems.

My research also has high synergy with the recent developments in IoT,

Internet of Things in cyber-physical systems.

At UCCS, I teach intro to computer security,

applied cryptography and wireless and embedded system security.

In this specialization, Bill and I will focus on applied cryptography.

>> The first course in this specialization covers classical cryptosystems and

many of the core concepts in cryptography.

We'll learn about a number of ancient and not so ancient cryptosystems.

Some noteworthy for their successes, but many more for their failures.

We'll not only explore how the field of cryptography was born and matured, but

use this as a vehicle to learn many of the key concepts and

terminology we'll be using throughout this specialization.

We'll learn about the difference between codes and cyphers and we'll

spend time learning about cryptanalysis, the breaking of codes and cyphers.

Finally, we'll explore one of the most fundamental building

blocks of modern cryptography, the hash function.

In the second course,

we will delve into the mathematics that underlies the bulk of modern cryptography.

In particular, we'll look at modular arithmetic in some depth,

paying particular attention to modular exponentiation and primality testing both

of which are central to most of today's asymmetric cryptographic protocols.

We'll also become familiar with the Chinese remainder theorem which provides

a very useful and powerful way to look at,

and work with the structure of numbers in a modular a modular arithmetic world.

>> In the next course, we will discuss about symmetric cryptography which

relies on shared secret key to ensure message confidentiality, so

that the unauthorized attackers cannot retrieve the message.

Then in the course Asymmetric Cryptography and Key Management, we will

introduce public keys which enables cryptographic applications not only for

message confidentiality, but also for authentication and integrity.

The use of public keys require asymmetric operations between the sender and

receiver, and the key distribution, and management.

>> We are excited to present to you the introduction to applied cryptography

specialization.

>> Welcome aboard.
