Introduction
(upbeat music) - Hello, my name's Eugene Spafford. I'm a professor of computer sciences at Purdue University, and I'm the Executive Director Emeritus of CERIAS, the Center for Education and Research in Information Assurance and Security at Purdue. Welcome to this course. We'll be covering some of the basic aspects of cryptography, what it is, how it's used, what are some of the components and challenges. The first thing I'll talk about is the purpose of this course and why encryption technologies are so important to the evolution of the internet and decentralized computing, that is the cloud. When we work in cyber, we want to protect against cyber crime, espionage, terrorism, protect privacy, and otherwise secure all of what we do. A component of good cybersecurity protection is cryptography. Cryptography can protect the confidentiality of data, even in the event of a compromise. Encryption is a cryptographic technique that ensures that security is present and ensures the safety of transactions. It protects data at rest, and it protects data in motion. This course introduces cryptography, including some history of secure communications, and some of the policy implications. Let's get started.
