About the Course

Welcome to Cryptography and Information Theory! This course combines cryptography (the techniques for protecting information from unauthorized access) and information theory (the study of information coding and transfer). More specifically, the course studies cryptography from the information-theoretical perspectives and discuss the concepts such as entropy and the attacker knowledge capabilities, e.g., Kerckhoff's Principle. It also contrasts information-theoretic security and computational security to highlight the different train of thoughts that drive the cryptographic algorithmic construction and the security analyses. This course is a part of the Applied Cryptography specialization....

Great introduction to cryptography. Professor was clear and concise in his explanations and the work required was reasonable. Overall a good experience, looking forward to the next class.

The course gave me very good basics in Cryptography. Especially, the attacker perspective, which is the most important aspect of Cryptography.

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!

A decent introductory overview but I would have liked less time spent on calculating entropy values and computational difficulty and more time on the theory, design and implementation of actual crypto algorithms.

This course requires more information on the topics. Due to less explanation and information on topics it becomes a bit difficult to solve questions. But all in all the course is good

Really good to start with the basics, the only problem is with the quizzes that are not to clear

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

Not the best I've followed on the the. Good enough but, IMHO, lacking of clear explanation on some concepts and some exercises are too generic and without a clear explanation (i.e. : many quizzes are difficult to do because the number of decimals to use is "revealed" only after a while.

Slides are totally useless. Some questions are formulated not so easy to understand for non-native English speakers. Confusion how to properly type the decimal numbers - use comma or dot as decimal separator. Not all terms are properly explained.

I find that numerical explanations are based on someone who already understands or knows about criptography. It's my first course in this matter and I believe the video explanations could be more detailed.

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