Overview

Class Central Tips

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.

Hello everyone, I’m Biddle McClooney , am from washington , United states . Married with 1kid , my purpose or aim for this short abbreviation story of mine is to educate on Digital assets investments such as crypto investments , NFT'S e.t.c and help interested individuals and investors to take precautions and measurement on an act, before commencing. I got carried away by the high profit return promised to me not knowing it was a ponzi scam I fell into, loss $864,389 to scammers year 2021-2022. May 7th I luckily bounced on a crypto recovery magazine and on it was TRust Guard Digital Assets recovery by Truman Jovani who happens to be my recovery expert under Trust Guard Digital Assets Recovery Contact : trustguarddigitalassetsrecovery AT aol DOT com , [email protected] after explaining to this great hacker he collected the scammer information from me and requested for my wallets address 24 hours interval and exactly 96 hours I got my funds on my wallet address. All thanks to Truman Jovani and Trust Guard Digital assets recovery expert team. .you can write him on w.h.a.t.s.a.p.p now @ +1 304 978-6205 .. or also email him via : [email protected] ........ trustguarddigitalassetsrecovery @ aol.com

This is a fun and engaging course, meant as a first introduction to cryptography and at the same time, exposes students to mathematics and concepts behind cryptographic primitives.

This course explains the inner workings of cryptographic primitives and how to correctly use them. It teaches how to reason about the security of cryptographic constructions and how to apply this knowledge to 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. It then examines many deployed protocols and analyzes mistakes in existing systems. Later parts of the course cover the relevant number theory, discuss public-key encryption and basic key-exchange, and expose students to many exciting open problems in the field.

One of the first sentences Prof. Boneh said in this class was "I am a big believer in note taking"... well I had preferred he did not took this so literally and had spoken at a slower pace, even if this had meant double the number of lessons.

The quizzes were ok, the programming assignments were fun but frankly there is a gap between what was presented in the video and what was required in the programming : to fill this gap a time far longer than presumed one was required.

My first MOOC. The course really allowed me to get a deep understanding of the underlying maths of some of the technologies I am somewhat familiar with. The maths at the end of the course, number theory, was quite new to me and therefore quite challenging. The course develops a nice rhythm and many concepts keep coming back which was pleasant for the most part. The most fun and learning came from the programming assignments. The numerous failure attempts followed by some readable decrypted output gives a wonderful victorious feeling.

A simply brilliant, albeit fast paced, introduction to basic concepts of cryptography. The course is fairly demanding because professor Boneh likes to put things out fast and this reflects to his way of lecturing. Personally I enjoyed his fast paced lectures, but it might be an acquired taste and some people might find the pace slightly too fast.

This was a difficult course, and it requires some previous experience with mathematics, otherwise you'll get stuck. The teaching style was fun, the examples were great, and the quizzes were sometimes a bit too difficult, but worth the trouble. The only flaw in this course is that the Cryptography II is, I quote a certain MOOC fellow colleague, "Duke Nukem among the MOOCs", since we're all waiting for the second part, and it's being moved to another starting date every couple of months, so... give us Crypto II! Please!

One of the first sentences Prof. Boneh said in this class was "I am a big believer in note taking". This class is a classic example of applying that quote. The pace was really fast, and if there wasn't the pause button, the class would be over my head.

The quizzes were ok, the programming assignments were the most fun.

I look forward for the next cryptography course offer.

I thought this course provided a very good fundamental understanding of cryptography. It was challenging but well worth the time. I especially thought the programming assignments were well chosen. They reinforced the lectures and were fun/challenging to solve. I look forward to taking Crypto II.

Good course to get a quick dive into cryptography in general. I was always interested in getting some basic knowledge. But on the fourth week I understood that's not what I'd like to study deep and connect my career with. So I dropped.

Course lacks good visualizations.
Programming assignments sometimes ambiguous. I didn't understood what is asked on 1st week's.

Very challenging. I wish Dr Boneh had talked a little slower and given more examples. I needed significantly more time each week than estimated.

The is a great course! It covers all the basics, diffie hellman, etc. It is difficult (i.e. not for beginners) and requires focus and time commitment.
This is worth taking and highly educational, you will learn a lot.

Interesting material, couldn't pass the first homework assignment though so I guess that means I fail the whole course? I find that disappointing.

Great great class. Lectures are amazingly concise and fast-paced, so (as Professor Boneh states) pausing and taking notes is very helpful. The homeworks and programming assignments are consistently difficult but manageable. I will be back for Crypto 2 :)

I enjoyed the course very much. I thought the lectures were well done. The problem sets and programming assignments were also well done. I took the first iteration in Spring 2012. There were a few late lectures (though the lectures were always well done), but I am sure that is taken care of now.

Very interesting but challenging MOOC.
Top quality content with an engaging delivery on a rather dry topic
Looking forward for MOOC part II on same topic, which has been annouced by Coursera

An extremely fun and well-designed introduction course to cryptography. The lecture videos are engaging and the programming assignments are interesting.

Great course. Challenging tasks, real life examples and good pace for the course. Highly recommended. Looking forward to the 2nd part.

A very interesting course, but it should be followed by self reading a good reference to completely understand the concepts
