16.2 IPSec Algorithms
The ESP and AH protocols are necessary to create a Security Association (SA), the foundation of an IPSec VPN. An SA is built from the authentication provided by the AH and ESP protocols. The primary function of key management is to establish and maintain the SA between systems. Once the SA is established, the transport of data may commence.
16.2.1 AH (Authentication Header) Protocol
AH protocol (RFC 2402) was designed for integrity, authentication, sequence integrity (replay resistance), and

This type of implementation does not protect the information from dissemination but will allow for verification of the integrity of the information and authentication of the originator.
