University of Colorado System による Symmetric Cryptography の受講者のレビューおよびフィードバック

The course is well designed and highly useful to every cryptographer. The lectures are very explanatory and understandable. But the DES pseudo code assignment is somewhat difficult for non computer science people.

Very good course that covers a lot of material on symmetric ciphers.

One possible area of improvement would be to cover some possible attacks specifically against symmetric ciphers. A bit of this is done when discussing the weakness of 2DES (MITM attack), which is very interesting. More of this would help reinforce the sense that cryptology is a combination of both coming up w/ better algorithms & breaking existing ones.

This course has deepened my interest in Cryptography. I am a fan of Da Vinci and ciphers. I am gonna dig a lot deeper in this. Thanks for providing the required directivity.

A great learning experience. I teach Cryptography in my Institution and this course helped me gain additional insights on the course.

Good course

Peer graded assignments are not good cheaters are being passed but people like me who write original content are being failed by mere 1 or two points by peers.People are literally copying codes from websites and are being graded and given certification of completion.Its really the sad truth.

Well laid-out course! It covers the essentials of symmetric cryptography crisply. The peer-graded assignments really helped me a lot in understanding the concepts more deeply. Quizzes are good, however, the feedback on answers could have been better. Certain concepts could have been explained in a bit more detail, so it is easier to understand certain quiz questions.

Million thanks to Sang-Yoon Chang for being great lecture for this wonderful online course. I've been learning a lot from your lectures and I will keep learning it for my future new career I am planning to achieve hopefully soon.

Good view of the basic Symmetric Crypto concepts. Theory is presented in an easy way to understand way. Professor is also super clear in his explanations.

Recommended :)

Very Great Course

learned many things many encryption technique in depth really great contents there

course design is brilliant. assignment questions are wonderful. peer review , flash quiz amazing.

Gives you a great explanation of the encryption algorithms and how they work

The course was very helpful. Thank you very much
