Abstract

This document describes an extension for TLS and DTLS to protect the server from Denial of Service attacks against the handshake protocol, carried out by an on-path adversary. The extension includes a nonce and a Message Authentication Code (MAC) over that nonce, encoded as a Handshake Token that a Trust Anchor entity computes and provides to the client. The server registered at the Trust Anchor verifies the MAC to determine whether continuing or aborting the handshake.
