About this course

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.

Everything was crystal clear but have to keep up with everything the professor says can't miss anything.

Very difficult course if you have no previous experience with cryptoanalysis and recent stats, but good because it makes you think!

Would have absorbed the course material more concretely if the instructor had slowed down on the pace at which concepts were being disseminated.

Excellent lectures. Mostly very easy to follow, but some mathematical points were ran through a bit too quickly and thinly.

An excellent introduction to the field of cryptography, from historical ciphers to ones commonly used today. Moving from weaker ciphers to stronger ones, and pointing out the weaknesses that led to the development of increasingly strong ciphers, lays out the motivation for continual cryptographic research very well.

This was a great introduction course to cryptography basics. It provided me with so much knowledge, from some history and how this field began, to different types of ciphers and hash functions, and even teaching me about modern uses of cryptography. I'm left with excitement and drive to learn more about it.
