Cryptographic Algorithm Implementation Requirements for Encapsulating Security Payload (ESP) and Authentication Header (AH)

They require an authentication header with the user's authentication key to be passed upon every request.

The KRB_AP_REQ message is referred to elsewhere as the “authentication header.

The KRB_AP_REQ message is often referred to as the authentication header.

The IP Authentication Header has the following syntax:

If need be, other protocol headers such as the IP Authentication header [1] may be inserted between the outer IP header and the inner IP header.
