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....

Provides a comprehensive introduction to cryptographic history, current technology, best practices and known attacker techniques. A great deal of material is covered in a relatively compact program.

This must be an incredibly difficult course to try to teach in six/seven weeks. There's a ton of material to cover and I appreciate that the course touches on all of the basics of crypto that are actually in use.

My only complaint is that some of the questions on the quizzes were really repetitive week-to-week. In particular, every week features a question (usually #3, if I remember correctly) that had you choose which constructions out of five choices were "secure" as per the definition of security for that week's topic. The problem was that the correct and incorrect answers were always similar, even though the security concept for each week was different! In other words, there are some things that will NEVER be secure for any crypto system. Every version of the question had several choices that fell into this category. It got to the point that I usually got the question correct on the first or second attempt without even trying that hard. In reality, that question should have required a lot more brain power from me because those security challenges are actually sometimes very subtle and difficult.

But that's truly my only criticism. I loved the course and the programming assignments. I'll be keeping an eye out for any more courses taught by Dr. Boneh.

Overall, a great course! There's always room for improvement. Certain complex and critical concepts were glossed over way too fast in the lectures (with speech compression in the recordings to boot), while other introductory material was gone over too slowly. There is an answer string evaluation problem in the Q's & A's where the required answer must contain a bullet dot to represent multiplication (an 'x' is not accepted) but the standard computer keyboard does not contain a bullet symbol, you have to be in a word processor to create that. Also, there are correct alternative answers for Q#'s 6,9, &12 in the Week 5 Quiz that need to be re-evaluated.

A very good course. The pace is quite high and the material is challenging. I think to get the best out of it you need to spend considerably more time than the course suggests each week and I was not able to do this. However, I have come out of the course with a good understanding of the basic concepts of cryptography and my interest in the subject has been piqued sufficiently to want to find out more!

Course was very fun to learn, and the instructor was very clear and concise with the lecture. I was slightly unprepared for the difficulty level and math involved, but reviewing the videos and discussion group cleared things up. Do not attempt this course without prior knowledge of some discrete math, otherwise it was a very in-depth course which covered many topics, and I would recommend it to peers.

I really enjoyed this course! Symetric security was quite easy for me. But when it came to public key security I felt so lost because of all that deep math. Maybe it may have better and more detailed explanation, but maybe it just my problem with math (which I'm aware and aknowledge even without this course :D).But definitely worth time spent. Waiting for Cryptography II now.

Thanks.

It would be really amazing if Dan tries to go lot more abstract in each video; and not explain the same concepts over and over again. I feel that it becomes particularly boring to keep hearing the recaps over and over again. In general, the course was a tough one for me! But the instructor, with his immense knowledge and great way of explaining things did create an impact!

Not a trival course, you should definitively pause the lessons several times in order to take notes.Some of the exams are far to be trivial. A little bit too theoretical, but gave me a good insight of topics I need to understand in my professional life. I would definitively recommend it

I liked the level commitment the programming problems demanded. It truly made you feel you had a deeper understanding of the subject after finishing them as opposed to just reading and answering multiple choice questions. Thanks for putting this together for the world to learn!

Some of the questions in the quizzes were vague and hard to comprehend. Also the professor's hand writing on the notes doesn't help since it's messy and the marker quality is not that good either.

Apart from the above, a good intro course to crypto, thanks.

A very good presentation of the theory of cryptography algorithms, but I'm disappointed that Crypto II is not available for now: some important points such as SSL/TLS crypto protocols or eliptic curves are not described at all in Crypto I.

The course is really what I wanted: It covers theoretical and practical aspect of cryptography. The exercises are also very well designed, although, I found some of them quite difficult.

Overall, I would recommend this course to a friend.
