Welcome to Cryptographic Hash and Integrity Protection! This course reviews cryptographic hash functions in general and their use in the forms of hash chain and hash tree (Merkle tree). Building on hash functions, the course describes message authentication focusing on message authentication code (MAC) based on symmetric keys. We then discuss digital signatures based on asymmetric cryptography, providing security properties such as non-repudiation which were unavailable in symmetric-cryptography-based message authentication. This course is a part of the Applied Cryptography specialization.

This course will help you build a foundation of some of the fundamental concepts in secure programming. We will learn about the concepts of threat modeling and cryptography and you'll be able to start to create threat models, and think critically about the threat models created by other people. We'll learn the basics of applying cryptography, such as encryption and secure hashing. We'll learn how attackers can exploit application vulnerabilities through the improper handling user-controlled data. We'll gain a fundamental understanding of injection problems in web applications, including the three most common types of injection problems: SQL injection, cross-site scripting, and command injection. We'll also cover application authentication and session management where authentication is a major component of a secure web application and session management is the other side of the same coin, since the authenticated state of user requests need to be properly handled and run as one session. We'll learn about sensitive data exposure issues and how you can help protect your customer's data. We'll cover how to effectively store password-related information, and not to store the actual plaintext passwords. We'll participate in coding assignment that will help you to better understand the mechanisms for effectively storing password-related information. Along the way, we’ll discuss ways of watching out for and mitigating these issues and be able have some fun and exploit two different vulnerabilities in a web application that was designed to be vulnerable, called WebGoat.

What makes WiFi faster at home than at a coffee shop? How does Google order its search results from the trillions of webpages on the Internet? Why does Verizon charge $15 for every GB of data we use? Is it really true that we are connected in six social steps or less? These are just a few of the many intriguing questions we can ask about the social and technical networks that form integral parts of our daily lives. This course is about exploring the answers, using a language that anyone can understand. We will focus on fundamental principles like “sharing is hard”, “crowds are wise”, and “network of networks” that have guided the design and sustainability of today’s networks, and summarize the theories behind everything from the social connections we make on platforms like Facebook to the technology upon which these websites run. Unlike other networking courses, the mathematics included here are no more complicated than adding and multiplying numbers. While mathematical details are necessary to fully specify the algorithms and systems we investigate, they are not required to understand the main ideas. We use illustrations, analogies, and anecdotes about networks as pedagogical tools in lieu of detailed equations. All the features of this course are available for free. It does not offer a certificate upon completion.

This course is the definitive introduction to blockchain for both the developer and non-developer audience. Beyond the technology, this course will introduce you to some of the philosophy behind decentralization and why there is so much excitement around it. During the first three modules, you'll be introduced to blockchain and the technology behind it. In module four, we'll go beyond bitcoin and delve deeper into a next-generation blockchain called Ethereum to introduce you to what modern blockchains can do. The use cases featured in the final module are drawn from among the businesses in ConsenSys' startup portfolio. We believe we're uniquely positioned to present you with a valuable behind-the-scenes look at the people and companies working in this space to help give you a better understanding of the business side of blockchain.

Computers are everywhere, they aren't just the desktops and laptops we use for work but the phones in our pockets and even the watches on our wrists are also computers. You probably use a computer every day and in fact you are reading this on a computer! Just because we use computers all the time, doesn't mean that we understand them, or find them easy to use. Computer Science is the science of computers, it is the field of knowledge that experts use to understand computer systems. Knowing a little computer science will help you understand the computers all around you. This isn't a how-to course for a particular piece of software, instead you will learn some fundamental concepts that you can apply to any software or computer system. You'll apply these concepts to the kind of computer systems we use every day, including word processing applications, e-commerce, the internet and web sites. You will learn how to apply computer science concepts to solve problems in daily computer use and generally be a better computer user. Taking this course could be the start of your career in computer science, and the course is an introduction to the Bachelors in Computer Science from University of London, but it is also for you if you just want to learn a little computer science to help you better understand the computers you use in your ordinary life.
