To provide security for the IP layer, IPSec defines two protocols: Authentication Header (AH) and Encapsulating Security Payload (ESP). These protocols provide security services for the SA. Each SA is identified by the Security Parameters Index (SPI), IP destination address, and security protocol ...
IP Security (IPSec) refers to a series of protocols defined by IETF to provide high quality, interoperable, and cryptology-based security for IP packets. By means of facilities including encryption and data origin authentication, it delivers these security services at the IP layer: l Confidentiality...

The gateway identifies the remote peer the IPsec VPN peers with and defines the appropriate parameters for that IPsec VPN. As we discussed earlier in this chapter, there are two types of gateways: those with static IP addresses and those with dynamic IP addresses (including remote clients). ...
Security protocols IPsec comes with two security protocols, AH and ESP. They define how to encapsulate IP packets and the security services that they can provide. · AH (protocol 51) defines the encapsulation of the AH header in an IP packet, as shown in Figure 3. AH can provide data ori...

IPSec uses two security protocols: Authentication Header (AH) protocol and Encapsulating Security Payload (ESP). Key exchange and SA establishment in IPSec is implemented by the IKE protocol, which simplifies use and management of IPSec. IPSec Security Protocol AH defines the authentication method and...
