Acerca del Curso

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.

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

Too delayed to earn this certificate because of not reviewed in the peer-graded assignment.I extended the due dates twice in April 13,2020 and April 20,2020 and now finally I got my certificate.This is the only negative thing that I felt.Please make sure that others peers wont get this complication.

Good for fundamental understanding, but lacks mathematical foundations. So, if u get the math behind what's happening, u will enjoy the course and the quizzes. If not, for a more mathematical approach, refer NPTEL's IIT KGP Course

The instructor is not teaching the stuff that comes in the quizzes which makes the quizzes very difficult to pass and he is not able to develop interest in the subject.
