学生对 马里兰大学帕克分校 提供的 密码学 的评价和反馈

Sadly, I was unable to comprehend everything I had seen. :(

I learned a lot in this course. I really appreciated. What I miss in several parts of the course is more examples. There are only a few examples in each lesson and with more examples it would be much easier.

Course provides practical understanding for cryptographic primitives without delving too deeply into the maths. I found the accompanying book (optional) to be of great value in enhancing the depth of material. Would have been helpful to spend a bit more time on SSL/TLS to solidify the knowledge.

Course was in good flow

Pretty nice course, on par with the more popular Coursera course Cryptography I by Dan Boneh - more of an introductory course for applied cryptography while Cryptography I is somewhat more theoretical. Useful introduction to DH and RSA. Purely optional programming assignments - .

There are too much materials for each week for a Hong Kong secondary school (middle school) student. The speed can be adjusted to a slower one, so as to allow more people to catch up the course.

A pretty dry topic, but the teacher manages to keep the interest up!

wonderful!!

Excellent!!

This course was enjoyable and challenging. Early lessons cover historical ciphers, along with some fun programming challenges to attack them.

Later lessons dive into modern cryptography. This is more challenging and you will need to study some number theory if you have not done so previously. I ended up buying Prof Katz' book and also Concrete Mathematics to fully get my head around the subject matter. The treatment is not superficial.

This is where I dropped one star from the review - I thought that the course could have done a better job of covering the theory in this space, or at least pointing to sources to study it, or mentioning it as a pre-requisite.

I also thought that the course could have done a better job of describing how all the pieces come together - the discussion is there, but it is light and somewhat assumed you will get it. The only thorough discussion is specifically for SSL / TLS late in the lecture series.

Overall, a good and challenging course. This is not an easy MOOC - so only take it if you are interested in a challenge and don't mind extra study time.

Very good

Funny workshops.

very nice course material, just it was stuffed with too much statistics

Great course. I learned a lot. It won't go deep enough for you to be able to implement the algorithms yourself, but it will give you a good understanding of how cryptography works. I realize it does not require a great deal of math, but it helps to have a mathematical mindset.

Nice teacher, but the course is tough for those who didn't know ABC of cryptography

Interesting review of all crypto basics, maths. It is an starting point, the first gate, then you may go deeper and discover more details and applications.

It was mostly theory . Wished for understanding about tools , etc. and see and perform some real things. I don't know , I expected a tad more.

Too fast...

Very complex, but interresting

I enjoyed the lextures. They covered a lot of material in very short time.

But i am deeply dissappointed of lack of examples, test exercises and disactive forum. If you dont get something right a way or you have any doubts, then you are sadly alone, because no-one is reading or giving correct answers on the forum;

good course

Very dull. Every time I try to watch a video, I find myself having a nap. Go for Cryptography I instead.

The way the course was tought increased the difficulty of the materials covered, needlesly.

They say that if you don't have anything good to say it's better not to say anything at all.

This is a good course for deciding if you want to pursue a more advanced degree in Cryptography, Computer Science, or Mathematics, but As part of a Cyber Security specialization, your paying customers are most likely working professional engineers or programmers, interested in practical applications of cryptography that they can use in order to create secure systems and services. This is a mathematics course and your paying customers are not going to use the knowledge from this course in their jobs. This is not an indictment of the instructor, but of the content itself. It is the wrong content for your target customer.
