Abstract
A first application layer at a first message processor identifies a first portion of context information. A second message processor receives the first portion of context information. A second application layer at the second message processor identifiers a second portion of context information. The second message processor sends the second portion of context information along with a first digital signature created from both the first and second portions of context information. The first message processor receives the second portion of context information and first digital signature. The first message processor sends a second digital signature created from the first and second portions of context information to the second message processor. If both the first and second digital signatures are authenticated, a secure context can be established between the first and second application layers.
