In this course, you will learn all of the old and modern security systems that have been used and are currently being used. You also learn how to crack each one and understand why certain security systems are weak and why others are strong. We will even go into RSA, AES and ECC which are the three main modern cryptosystems used today.
Learn How to Crack the Code!
Master the Art of Security!
Security is a very important tool, and the ability to use mathematics to hide information is vital to the world. See how our banks and even the National Security Agency (NSA) keeps their data secure. With the knowledge of this course, you can even apply for security jobs at places like the NSA! This is a course that is rarely taught in Universities, so take advantage and start today!
Most of today's security is based upon RSA, and AES but the NSA is trying to push Elliptic Curve Cryptography since it is more secure than RSA. In this course, we learn all of these cryptosystems and their weaknesses. We give examples of every cipher that we cover. Only a small number of people currently understand these systems, and you can join them. The best part of this course is the fun in breaking the codes. We offer many examples of each cryptosystem and how to break each one.
Even as you are reading this, your https:// at the top says that the RSA Algorithm is successfully keeping your information from flooding the internet. You can find out how it all works and the mathematical structures that keep it secure in this course. So what are you waiting for?
Learn how to encrypt and decrypt the Ceaser Cipher and learn why it is a weak cryptosystem
See some examples on the Shift Cipher and learn how to hack it without knowing the key
Learn how to encrypt and decrypt the Affine Cipher and why it is so much stronger than the shift cipher and learn about frequency analysis and why it is so useful in attacking old cryptography
Learn how to use online calculators for frequency analysis and how to use that to crack the Affine cipher without the key
Learn what a block cipher is and why they are so much more secure, and learn how to crack the Vigenere cipher without the key
See some examples of encrypting and decrypting the Vigenere cipher and see how to find the key length (which would then crack the system entirely)
Understand how the Playfair cipher works and why it is so fun and secure
Watch a more visually appealing lecture on the Playfair cipher and examine the weaknesses
Completely understand the AES Cryptosystem (each step) and learn why it is so secure and used today. Learn how to encrypt a message
Watch a more visually appealing lecture on how to encrypt using the AES cryptosystem and see applications of it on your wireless router and wireless connection (we will show using Windows 7)
Understand the most modern cryptosystem today: the RSA cryptosystem. Learn how to encrypt, decrypt and attack it without the key. Understand what a public key cryptosystem is and why it is so secure. Learn the strength behind factorization and why it is a problem that we can bet our crpytosystems on. Find out why knowing how to attack the cryptosystem still makes it secure.
Learn the ins and outs of the RSA cryptosystem and where it is used on the internet (We use a Bank of America example and see their RSA cryptosystem) and see how big security is today
In this lecture, we introduce the most modern cryptosystem: elliptic curve cryptography. See where its applied today and why it is not as widely used yet (but likely will be within the next decade).
Math can be hard, but it doesn't have to be!
I love what I teach. I feel like math has a negative connotation to it, and that it is the teacher's job to build enthusiasm and interest through their own passion for the subject. Right now, most students take their math classes just to get the degree requirements - and I respect that - but I also want the student to enjoy what they are learning. This can be hard to do, but I am willing to try my best. When students hit a wall in their mathematics career, then they need someone to help them back up. My goal is to be that person. I have seen how many professors teach, and there are many styles that I like to incorporate. I like to show math in a different and interesting perspective that hopefully is also applicable.
