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,One of the best courses on hashing in cryptography... Message authentication is to protect the message integrity and to perform sender authentication. This module describes message authentication code (MAC) which is based on symmetric keys. It contrasts MAC with hash functions or general encryption/decryption techniques and quantify the brute force attack difficulty for MAC and discuss the security requirements for MAC. The module also reviews two MAC implementations in Data Authentication Algorithm (DAA) and Cipher-Based MAC (CMAC), which are based on the use of block ciphers.
