Cryptography: A Hands-on Approach Download For Free


Secret-key encryption, one-way hash, public-key cryptography, digital signature, PKI, TLS, cryptocurrency and blockchain

What you’ll learn
Study the basic principles of cryptography, including secret-key encryption, one-way hash function, and public-key cryptography
Study various crypto applications, including authentication, digital signature, HTTPS, credit card, blockchain, cryptocurrencies, etc.
Study the Public Key Infrastructure (PKI) and the TLS protocol, which are essential for securing communication on the Internet
Understand the risks faced by various crypto algorithms and protocols, and how these risks can be mitigated
Understand the common mistakes in the use of crypto
Gain hands-on experiences through 8 crypto labs (SEED Labs) developed by the instructor

No programming background is needed, but to work on the hands-on labs, some basic Python programming background is needed
Cryptography is a foundation in cybersecurity. It is the underlying building block of many defense mechanisms, systems, and protocols. Without crypto, we will not be able to safely conduct many things on the Internet, such as web browsing, online banking, working remotely, etc. Without crypto, blockchain and cryptocurrency will not exist.

In this course, we systematically study the basic principles of cryptography. In particular, we focus on the three essential pillars of cryptography, including secret-key encryption, one-way hash function, and public-key cryptography. We study how they work and how they are used in the real-world applications. We also look at the risks they face, and how these risks are mitigated in the real world. Furthermore, we study the common mistakes people make when using crypto algorithms and protocols. We show how these mistakes can be exploited in attacks.

The course emphasizes hands-on learning. For each topic covered, students not only learn the theory, they also get to work on the hands-on exercises developed by the instructor. These exercises are called SEED labs, and they are being used by over 1000 institutes worldwide. The course is based on the widely-adopted textbook written by the instructor. The title of the book is “Computer & Internet Security: A Hands-on Approach”.

Who this course is for
Undergraduate and graduate students studying cybersecurity
Anyone who is interested in learning the cryptography basics, especially the applied aspects of crypto
Anyone who is interested in gaining a deeper understanding of how various crypto-based systems work
Anyone who is interested in learning how blockchain and cryptocurrencies work
