18.2.1 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), AES (Advanced 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. Refer to
Section 19.2 on
page 308 for more information.
