Cryptography for InfoSec

Applied Cryptography essentials for information security researchers

Historically, cryptography was used to ensure private communication between two people with some prior relationship. More recently, its scope has expanded to include things as diverse as data integrity, secure internet-wide communication, electronic cash, secure distributed computation, and more.

Cryptography has also become ubiquitous. Perhaps unknowingly, we have all encountered applications of cryptography in our daily lives---whether by logging in using a password, making a web purchase over a secure connection, or applying a software update that is digitally signed.

This course will introduce you to the foundations of applied cryptography from the perspective of a security researcher. Students will learn how to reason about the security of cryptographic constructions and how to apply this knowledge to real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems.

Intended Audience: students, security enthusiasts
