Description

This lecture covers symmetric cryptography algorithms for integrity, focusing on CBC-MAC. It explains how to achieve confidentiality and integrity using symmetric encryption, emphasizing the importance of Message Authentication Codes (MAC) with fixed-size keys. The lecture also delves into the concept of turning a block cipher into a MAC, specifically discussing CBC-MAC and its deterministic nature. Additionally, it explores different approaches like ENCRYPT-AND-MAC and ENCRYPT-THEN-MAC to ensure both confidentiality and integrity of data. The lecture concludes with an overview of Authenticated Encryption with Associated Data (AEAD) and modern constructions to enhance security.
