From: Introduction to Cryptography Course Team <noreply@coursera.org> Sent: Monday, January 28, 2013 8:28 AM To: jeeproject@yahoo.com Subject: Online Cryptography class: week 3 Dear Jeffrey epstein, The week 3 lectures and problem set are posted on the course web site at https://crypto.stanford.edu/OnlineCrypto The problem set is due in three weeks. This week's topic is data integrity and we will discuss a number of classic constructions for MAC systems. For now we only discuss how to prevent modification of non-secret data. Next week we will come back to encryption and show how to provide both confidentiality and integrity. This week's programming project shows how to authenticate large video files. Even if you don't do the project, please read the project description since it teaches an important concept called a hash chain. As always, the discussions on the course forums are very instructive. Please continue posting your questions and feedback.
