The course is brilliant! Mr Chang explains everything clearly, so that you can understand the material even if you don't have much time to deal with it.

By learning this course i have gained some extra knowledge in cryptography. This course helped me to complete my final year project.

This course helps in developing research and teaching skills.The overall course contents covered were excellent.

Thank You.

A very neat and easy to follow course that introduces the basic concepts of cryptography and its use in modern world!

Good course...provides the fundamental idea behind the relationship between cryptography and information theory...

The course mainly covers criteria for security. I need more of cryptography in it. Its not completely useful.

This is fabulous course that i found, great assignment and questions make this course course worth full.

good information about cryptography and entropy and information theory

Interesting both theoretical and practical part of the course

Learn new concept - Entropy information

It's ok, it's easy to learn! THX!

Simple, and effective :-)

very very useful for me

EXCELLENT

basics

Overall really good. Instructor sometimes mispeaks and then writes something different down during the math sessions. This happens a couple of times with variable names. When mixed with some questionable handwriting which I assume is due to the digitizer it makes it hard to follow and you have to rewind to figure out what he meant instead of what he said but this is only a few times and it is possible. Overall I like the instructor, I like the content, and I learned.

The course was quite superficial on some topics, but keeping in mind that this is mostly a ramp-up to subsequent crypto courses, I think it was OK. The whiteboard segments are great, probably the best part of the course. The instructor is clear and pleasant to listen to. Spreading it over 4 weeks is too generous, it could probably be shortened to 3 or even 2. Thanks!

It is ok. not a lot of math. Ok for busy people.

perfect for beginning with cryptography.

too short explanations sometimes

a basic course to start with

Nice course and lectures

Nice one for beginners

It's a good course if you are getting started in cryptography. But , for people having a rudimentary knowledge of math especially probability and the Alice-Bob-Eve terminology in cryptography may skip it and jump right into the 2nd course. But, the teacher is a really good communicator and the course is very good to get started with cryptography. I was able to finish this course in around 2 days with prior knowledge in crypto

The instructor is not clearly showing his idea; however, the course is an abstract overview.
