About the Course

Welcome to Cryptographic Hash and Integrity Protection! This course reviews cryptographic hash functions in general and their use in the forms of hash chain and hash tree (Merkle tree). Building on hash functions, the course describes message authentication focusing on message authentication code (MAC) based on symmetric keys. We then discuss digital signatures based on asymmetric cryptography, providing security properties such as non-repudiation which were unavailable in symmetric-cryptography-based message authentication. This course is a part of the Applied Cryptography specialization....

course is excellent and I hope it would be better if there is an advanced level specialisation continuation for this specialisation

This is a very solid course but the "peer grading" requirement needs to be changed. I finished the course on the first or second day of November and had to log on multiple times a day every day until now (Nov 29) to finally get my peer reviews done. The course clearly does not have enough traffic to justify every student doing 3 peer reviews. The requirement should be definitely be reduced - at least to 2 and possibly all the way to one.
