Abstract

The current architecture of the Internet where anyone can send anything to anybody presents many problems. The recipient of the connection might be using a mobile access network and thus unwanted incoming connections could produce a high cost to the recipient. In addition, denial of service attacks are easy to launch. As a solution to this problem, we propose the Recipient Controlled Session Management Protocol where all incoming connections are denied by the default and the recipient of the connection can choose using certificates what incoming connections are allowed. The recipient can also revoke rights for making an incoming connection at any time.
