Welcome to the Classical Cryptosystems and Core Concepts course.
the undergraduate Introduction to Applied Cryptography specialization.
the study of secure communications.
We will build on this knowledge in later courses.
and what some of the challenges are to achieving those goals.
the concepts we will discuss within a meaningful context.
the materials related to the specialization as a whole.
which I call Cryptographic Tidbits.
the cryptologic world and we won't go into any of it too deeply.
computer technology began driving fundamental changes in the cryptographic world.
and what our security goals are in light of that threat model.
the development of modern cryptosystems.
which is essentially the breaking of codes and ciphers.
see some examples that have changed the course of history.
including one that was believed unbreakable for about 300 years.
we'll focus on hash functions.
and the properties that we want a good cryptographic hash function to possess.
discrete math that are the foundation of many of our current cryptosystems.
modern symmetric ciphers and another on asymmetric cryptography.
I hope you enjoy the journey and learn a lot along the way.
