Entire course: ➡️    • Fundamental TLS - Transport Layer Security   ⏰ Timestamps for content in this video ⏰ 00:00 Authenticity as a security goal 01:17 HMAC message authentication code 04:05 Encrypt-then-MAC authenticated encryption 08:46 GCM AEAD block cipher mode of operation 🔷🔷 About 🔷🔷 This lesson on TLS – Transport Layer Security – is the 5th of 6 parts providing the essentials of cryptography just enough to later understand the cryptographic processes taking place within TLS. This 5th part has a closer look at the security goal of authenticity and outlines, how message authentication codes (MAC), authenticated encryption (AE), and authenticated encryption with associated data (AEAD) are three cryptographic concepts serving authenticity. The lesson also presents, how a hash-based message authentication code (HMAC) as a cryptographic primitive is a specific type of MAC, how Encrypt-then-MAC approaches are instances of AE, and how the Galois/Counter Mode (GCM) block cipher mode of operation is an instance of AEAD. 🔗 Links included in this video 🔗 [1] https://en.wikipedia.org/wiki/HMAC [2] https://en.wikipedia.org/wiki/Authent...
