The Use of Galois Message Authentication Code in IPsec ESP and AH

Overview

RFC 4543, “The Use of Galois Message Authentication Code in IPsec ESP and AH”, is a Proposed Standard document published in May 2006 by D. McGrew, J. Viega. The canonical text is published by the RFC Editor.

Abstract

This memo describes the use of the Advanced Encryption Standard (AES) Galois Message Authentication Code (GMAC) as a mechanism to provide data origin authentication, but not confidentiality, within the IPsec Encapsulating Security Payload (ESP) and Authentication Header (AH). GMAC is based on the Galois/Counter Mode (GCM) of operation, and can be efficiently implemented in hardware for speeds of 10 gigabits per second and above, and is also well-suited to software implementations. [STANDARDS-TRACK]
