Cisco Cisco Packet Data Gateway (PDG)
Usage Guidelines
IKEv2 requires an integrity algorithm be configured in order to work.
A keyed-Hash Message Authentication Code, or HMAC, is a type of message authentication code (MAC)
calculated using a cryptographic hash function in combination with a secret key to verify both data integrity
and message authenticity. A hash takes a message of any size and transforms it into a message of a fixed size:
the authenticator value. This is truncated and transmitted. The authenticator value is reconstituted by the
receiver and the first truncated bits are compared for a 100 percent match.
