Galois/Counter Mode: Applications, Use & Performance

In cryptography, Galois/Counter Mode (GCM) is a mode of operation for symmetric-key cryptographic block ciphers. The proposal was first published in 2007. The GCM algorithm belongs to the class of authenticated encryption with associated data (AEAD) methods. Given a key K {\displaystyle K} , plaintext P {\displaystyle P} , and associated data A D…
