Title : Implicit IV for Counter-based Ciphers in IPsec
Authors : Daniel Migault

Abstract:
IPsec ESP sends an initialization vector (IV) or nonce in each
packet, adding 8 or 16 octets. Some algorithms such as AES-GCM, AES-
CCM, AES-CTR and ChaCha20-Poly1305 require a unique nonce but do not
require an unpredictable nonce. When using such algorithms the
packet counter value can be used to generate a nonce, saving 8 octets
per packet. This document describes how to do this.
