課程概述

Welcome to Symmetric Cryptography! Symmetric cryptography relies on shared secret key to ensure message confidentiality, so that the unauthorized attackers cannot retrieve the message. The course describes substitution and transposition techniques, which were the bases for classical cryptography when the message is encoded in natural language such as English. Then, we build on product ciphers (using both substitution and transposition/permutation) to describe modern block ciphers and review the widely used cipher algorithms in DES, 3-DES, and AES. Lastly, we enable the use of block ciphers to support variable data length by introducing different modes of block cipher operations in ECB, CBC, CFB, OFB, and CTR modes. This course is cross-listed and is a part of the two specializations, the Applied Cryptography specialization and the Introduction to Applied Cryptography specialization....

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.

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.\n\nRecommended :)

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.

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.
