课程概述

In this MOOC, we will learn the basic concepts and principles of crytography, apply basic cryptoanalysis to decrypt messages encrypted with mono-alphabetic substitution cipher, and discuss the strongest encryption technique of the one-time-pad and related quantum key distribution systems. We will also learn the efficient symmetric key cryptography algorithms for encrypting data, discuss the DES and AES standards, study the criteria for selecting AES standard, present the block cipher operating modes and discuss how they can prevent and detect the block swapping attacks, and examine how to defend against replay attacks. We will learn the Diffie-Hellman Symmetric Key Exchange Protocol to generate a symmetric key for two parties to communicate over insecure channel. We will learn the modular arithmetic and the Euler Totient Theorem to appreciate the RSA Asymmetric Crypto Algorithm, and use OpenSSL utility to realize the basic operations of RSA Crypto Algorithm. Armed with these knowledge, we learn how to use PHP Crypto API to write secure programs for encrypting and decrypting documents and for signing and verify documents. We then apply these techniques to enhance the registration process of a web site which ensures the account created is actually requested by the owner of the email account....

The course content is excellent. It would be much better if some errors (like misspelled words, improper capitalization etc) would be corrected

This Course is good but difficult for learner. To provide better knowledge as expert level course should be extended.

Professor consistently drops the ball and allows the AWS credits to expire inside this course. You cannot complete it as of 12/20/2019. Coursera is not able to fix this, Amazon says to talk to Coursera. Coursera says to talk to the Professor, and the Professor doesn't respond to his campus emails.

You'll need some kind of pre-requisite computer programming knowledge to complete the course. The material given in the course is not sufficient for proper learning.

The course videos aren't creative and very monotonous. Boring.
