Are you familiar with the overall remote configuration or zero-touch configuration sequence? If not - take a look at the FAQ (http://communities.intel.com/docs/DOC-1490)
Have you looked at the video - "Using Manageability Tool to perform remote configuration (v0.28)" - available at http://software.intel.com/en-us/articles/download-the-latest-version-of-manageability-developer-tool-kit/
In that demonstration - the author already had the remote client provisioned, and is showing how to use a custom\in-house generated certificate. The author assigns\updates that certificate to the client, full unconfigures AMT on the client, and then initiates a configuration session.
