课程概述

A prominent expert in the number theory Godfrey Hardy described it in the beginning of 20th century as one of the most obviously useless branches of Pure Mathematics”. Just 30 years after his death, an algorithm for encryption of secret messages was developed using achievements of number theory. It was called RSA after the names of its authors, and its implementation is probably the most frequently used computer program in the world nowadays. Without it, nobody would be able to make secure payments over the internet, or even log in securely to e-mail and other personal services. In this course we will start with the basics of the number theory and get to cryptographic protocols based on it. By the end, you will be able to apply the basics of the number theory to encrypt and decrypt messages, and to break the code if one applies RSA carelessly. You will even pass a cryptographic quest! As prerequisites we assume only basic math (e.g., we expect you to know what is a square or how to add fractions), basic programming in python (functions, loops, recursion), common sense and curiosity. Our intended audience are all people that work or plan to work in IT, starting from motivated high school students....

Some of the material is a bit hard to follow at times, but it's quite interesting and the final Quest quiz is a nice and fun way of putting everything together.

Excellent course to learn number theory principles and relate them to asymmetric cryptosystems. The course is highly rigorous and challenging.

In general, this course is much better than the previous 3, and I enjoyed all weeks but Week 4. I think Michael Levin should improve his explanations, and also try to give further examples about the algorithms he is talking about. I would say that it is worthy taking this course, but I really hope Week 4 can be improved.
