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

Simple, and effective :-)

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

EXCELLENT

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.

too short explanations sometimes

very very useful for me

Interesting both theoretical and practical part of the course

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.

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