IKE Negotiation

The Internet Key Exchange (IKE) protocol is used to exchange security

options between two hosts who want to communicate via IPSec. The first

phase of the protocol authenticates the two hosts to each other and

establishes the Internet Security Association Key Management Protocol

Security Association (ISAKMP SA). The second phase of the protocol

establishes the cryptographic parameters for protecting the data passed

through the tunnel, which is the IPSec Security Association (IPSec SA). The

IPSec SA can periodically be renegotiated to ensure security.
The IKE protocol can use one of two modes:

Main Mode

, which provides

identity protection and takes longer, or

Aggressive Mode

, which provides

no identity protection but is quicker. With Aggressive Mode, there is no

negotiation of which cryptographic parameters will be used; each side must

give the correct cryptographic parameters in the initial package of the

exchange, otherwise the exchange will fail. If Aggressive Mode is used, the

IKE Encryption

IKE Authentication

, and

IKE DH Group

must be

specified.

IKE Version

IKE Version settings to be used. Currently the accepted values are IKEv1,

IKEv2 and Any. Default is IKEv2. Any uses IKEv2 when initiating but will

accept any protocol version while responding.

It is recommended that any IKE Encryption or ESP Encryption parameters

that are selected be supported by the IKE Version that is used. Refer to the

list of

IKEv1

and

IKEv2

cipher suites for more information.

IKE Encryption

The type of encryption,

3DES

AES

AES192

AES256

, used for IKE

negotiation. Any can be selected if the two sides can negotiate which type of

encryption to use.

Note:

If IKE Encryption, Authentication and DH Group are set to

Any

default cipher suite(s) will be used. If the console manager acts as an

initiator, the tunnel will use a default IKE cipher of aes128-sha256-ecp256

(for IKEv1). For IKEv2 or when the console manager is the responder in

tunnel initiation, it will propose a set of cipher suites and will accept the first

supported proposal received from the peer.

IKE Authentication

The type of authentication,

SHA2_256

SHA2_384

SHA2_512

SHA1,

MD5

, used for IKE negotiation.

Any

can be selected if the two sides can

negotiate which type of authentication to use.

IKE DH Group

The Diffie-Hellman Group, 2 (modp1024), 5 (modp1536), 14 (modp2048),

15 (modp3072), 16 (modp4096), 17 (modp6144), 18 (modp8192) or 19

(ecp256) can be used for IKE negotiation. Any can be selected if the two

sides can negotiate which Diffie-Hellman Group to use.
