課程概述

Cryptography is an indispensable tool for protecting information in computer systems. In this course you will learn the inner workings of cryptographic systems and how to correctly use them in 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. The second half of the course discusses public-key techniques that let two parties generate a shared secret key. Throughout the course participants will be exposed to many exciting open problems in the field and work on fun (optional) programming projects. In a second course (Crypto II) we will cover more advanced cryptographic tasks such as zero-knowledge, privacy mechanisms, and other forms of encryption....

Cutting edge cryptography topics. Good explanations and slides, but pause button is highly recommended. Can be a bit too mathematical for the general public, and not very formal for mathematicians.

This course gives is perfect to start learning cryptography, explanations are detailed, topics carefully selected combining theory with real world examples and making emphasis in important details.

The course is clear and goes at a sustained but correct pace. I really like the fact to show the weakness to understand what are the requirements of a secure PRF, PRP & co!

Optional programming assignments are really interesting unfortunately they take too much time to do and lack of guidance as it could be the case for the famous ML course. At least the first exercises should provide a development environment to get familiar with: hex, crypto libs, dictionary research, stats algorithms implementation ...

The first two weeks lack of in-video tests.

Very nice course , sometimes along there was some difficulty occurs but the support staff n teacher helps me a lot.Some practical implementation also missing from course.

a little bit hard for no computer basic people

El profesor es muy malo explicando, hay cosas las cuales no tenian sentido (creo yo que esto es porque justamente el profesor no sabe y explicar) y ademas las preguntas que hace en medio de los videos son ridiculas. Da preguntas sin haber antes explicado el conocimiento previo.

Very theoretical and mathematical and not enough real examples.

There were too many repititions of tautological proofs. Should have been covered in 1/2 or more of a single session: this is how we reason about cryptography. Too much focus on low-level primitives which doesn't make sense if we are to never implement our own cryptography. Finally, as a general point it would be amazing if there were ungraded "practice sets" that came with answers: you work it work them out and look at the answers and if you don't understand you try to figure out what you can't get. You can ask questions on the forum without revealing anything. The focus should be on working problems. Then, the quiz needn't permit infinite retrials: working through the practice sets is where the learning would occur. As it is now, you listen to the lecture, read over the notes several times, and then try the quiz. I did the programming before taking the quiz: that was a chance to actual work with the crypto algorithms.

A really hard class for anyone not graduated from collage.

This isn't a beginners course. I dropped out in first week. I took every note I could and reviewed again and again. I really think the instructor is an intelligent man, but I'm not quite sure he understands how to teach well. I'm really disappointed that I didn't get to take anything away from this class.

Should have come with an explanation that non IT background people cannot apply
