rfc.4353 - The Use of Galois Message Authentication Code (GMAC) in IPsec ESP and AH
23.05.2006
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.
