From Wikipedia, the free encyclopedia. The data to sign is exchange- specific.

Key Exchange Data variable length – Data required to generate a session key. At step 3ePDG take out the information from the information e. I put the step number of 3GPP procedure on the right end of Wireshark log.

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 configured they might appear at either end.

Refer to RFC for details. February Learn how and when to remove this template message. Lke that this message is a response to a message containing the same message ID.


At Step 8. SIG is the signature payload.

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 on both sides. Kaufman Microsoft December IKEv1 consists of two phases: Indicates specific options that are set for the message.

A significant number of network equipment vendors have created their own IKE daemons rf IPsec implementationsor license a stack from one another.

How can a device or a server 249 do DPD? This includes payloads construction, the information payloads carry, the order in which they are processed and how they are used. At Step 14. If you are interested in 3GPP based device e. Nonce Data variable length – Contains the random data generated by the transmitting entity. The presence of options is indicated by the appropriate bit in the flags field being set.
