At Step 7. At Step 8. If you are interested in 3GPP iks device e. IKEv1 consists of two phases: An Unauthenticated Mode of IPsec. In this case, user identity is not requested.

RFC – The Internet Key Exchange (IKE)

The IETF ipsecme working group has standardized a number of extensions, with the goal of modernizing the IKEv2 protocol and adapting it better to high volume, production environments. Identification Data variable length – Contains identity information.

Following sequence is based on RFC 2. The method is very simple. The IKE protocol uses UDP packets, usually on portand generally requires 4—6 packets with 2—3 turn-around times to create an SA security association uke both sides. At step 4. Indicates that this message is a response to a message containing the same message ID. Requesting an Internal Address on a Remote Network.

Internet Key Exchange (IKE) Attributes

If not, it considers the other party is dead. AAA Server identity the user. Key Exchange Data variable length – Data required to generate a session key. Actually Step 1 ik made up of two sub steps as follows: Kernel modules, on the other hand, can process packets efficiently and with minimum overhead—which is important for performance reasons.

At step 2UE sends following ID.

This lke was last edited on 19 Decemberat At Step 13. If unused, then this field MUST be set to 0. The IKE specifications were open to a significant degree of interpretation, bordering on design faults Dead-Peer-Detection being a case in point [ citation needed ]giving rise to different IKE implementations not being able to create an agreed-upon security association at all for many combinations of options, however correctly kke they might appear at either end.

The presence of options is indicated by the appropriate bit in the flags field being set. It is designed to be key exchange independant; that is, it is designed to support many different key exchanges. A significant number of network equipment vendors have created their own IKE daemons and IPsec implementationsor license a stack from one another.

At step 2. OCF has recently been ported to Linux. Implementations vary on how the interception rcf the packets is done—for example, some use virtual devices, others take a slice out of the firewall, etc.

UE checks the authentication parameters and responds to the authentication challenge. AAA Server initiate the authentication challenge.

At 4209 12. Refer to RFC for details. For instance, this could be an AES key, information identifying the IP endpoints and ports that are to be protected, as well as what type of IPsec tunnel has been created.

Nonce Data variable length – Contains the random data generated by the transmitting entity. Originally, IKE had numerous configuration options but lacked a general facility for automatic negotiation of a well-known default case that is universally implemented.
