Introduction to IPSec
Figure 26-3 IPSec Architecture
26.2.1 IPSec Algorithms
The ESP (Encapsulating Security Payload) Protocol (RFC 2406) and AH (Authentication Header) protocol
(RFC 2402) describe the packet formats and the default standards for packet structure (including
implementation algorithms).
The Encryption Algorithm describes the use of encryption techniques such as DES (Data Encryption
Standard) and Triple DES algorithms.
The Authentication Algorithms, HMAC-MD5 (RFC 2403) and HMAC-SHA-1 (RFC 2404, provide an
authentication mechanism for the AH and ESP protocols. Please see section 27.2 for more information.
26.2.2 Key Management
Key management allows you to determine whether to use IKE (ISAKMP) or manual key configuration in
order to set up a VPN.
