15.11 IKE Phases
There are two phases to every IKE (Internet Key Exchange) negotiation – phase 1
(Authentication) and phase 2 (Key Exchange). A phase 1 exchange establishes an IKE SA and
the second one uses that SA to negotiate SAs for IPSec.
Figure 84
Two Phases to Set Up the IPSec SA
In phase 1 you must:
• Choose a negotiation mode.
• Authenticate the connection by entering a pre-shared key.
• Choose an encryption algorithm.
• Choose an authentication algorithm.
• Choose a Diffie-Hellman public-key cryptography key group (
DH1
or
DH2
)
.
• Set the IKE SA lifetime. This field allows you to determine how long an IKE SA should
stay up before it times out. An IKE SA times out when the IKE SA lifetime period
expires. If an IKE SA times out when an IPSec SA is already established, the IPSec SA
stays connected.
Authentication
Algorithm
Select
SHA1
or
MD5
from the drop-down list box.
MD5
(Message Digest 5) and
SHA1
(Secure Hash Algorithm) are hash algorithms used to authenticate packet
data. The
SHA1
algorithm is generally considered stronger than
MD5
, but is
slower. Select
MD5
for minimal security and
SHA-1
for maximum security.
