AES-GCM

Definitions

1. A mode of operation for AES that provides both confidentiality and integrity through authenticated encryption, using Galois/Counter Mode. It is common in modern protocols because it can encrypt and detect tampering efficiently.

   In plain English: A modern AES mode that both encrypts data and checks if it was altered.

   Example: "The protocol switched to AES-GCM so ciphertext tampering would be detected instead of silently producing garbage."
