UE checks the authentication parameters and responds to the authentication challenge. 2490, IKE had numerous configuration options but lacked a general facility for automatic negotiation of a well-known default case that is universally implemented.

As you may guess from the terminology itself, it is a method that is used for Internet Security.

At step 2. The presence of options is indicated by the appropriate bit in the flags field being set. Overall key exchanging protocol sequence in At step 2UE sends following ID. AAA Server identity the user. If it does not get any response for a certain duration, it usually delete the existing SA. At step 4.

This includes payloads construction, the information payloads carry, the order in which they are processed and how they are used. By using this site, you agree to the Terms of Use and Privacy Policy. At step 3.

The data to sign is exchange- specific. These tasks are not performed by each separate steps, they are all performed in a signal back-and-forth. I will summarize on some of the important parameters later. At Step 9.

At Step 15. IKE has two phases as follows: If it recieves the response, it consider that the other party is alive. Actually Step 1 is made up of two sub steps as follows: At Step 7UE checks the authentication parameters and responds to the authentication challenge. If you have wireshark log, you can easily look into the details of the data structure. 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.

This constrains the payloads sent in each message and orderings of messages in an exchange. The following issues were addressed: Refer to RFC for details. This is from Figure 8.

If unused, then this field MUST be set to 0. Key Exchange Data variable length – Data required to generate a session key.

Kaufman Microsoft December The relationship between the two is very straightforward and IKE presents different exchanges as modes which operate in one of two phases.

Indicates that this message is a response to a message containing the same message ID. At Step 11. Views Read Edit View history. Identification Data variable length – Contains identity information.

At Step 14.
