17 IPsec concepts DRAFT: BROCADE CONFIDENTIAL Figure 60 provides a basic visual comparison of how transport mode and tunnel mode modify an IP datagram. FIGURE 60 Transport mode and tunnel mode comparison IPsec header options IPsec adds headers to an IP datagram to enable authentication and privacy. There are two options: • Authentication Header (AH) • Encapsulating Security Payload (ESP) Authentication Header AH can be used to authenticate a data stream, but does not provide encryption needed for privacy. The AH contains a message authentication code (MAC). The MAC is created by a hash algorithm calculation. The MAC is transmitted in an IP datagram. The same hash algorithm is then used by the receiver to verify the integrity of the packet. AH can be used in either transport mode or tunnel mode, as shown in Figure 61. FIGURE 61 AH header in transport mode and tunnel mode 230 Web Tools Administrator's Guide 53-1001772-01
