3.3.5 Message Processing Events and Sequencing Rules
To publish the connection string by using Secure Peer Name initiation, the connection string MUST first be encrypted as defined in section 3.3.5.1. Next, a Secure Peer Name MUST be created as specified in section 3.3.5.2.
The [MS-RA] protocol defines a Remote Assistance Contact Information message that is used after a Remote Assistance connection is made using an Unsecured Peer Name. The Remote Assistance Contact Information message allows the publisher and consumer to exchange public keys and Secure Peer Names that match these public keys.
