Abstract

   The Dynamic Host Configuration Protocol for IPv6 (DHCPv6) enables
   DHCPv6 servers to pass configuration parameters.  It offers
   configuration flexibility.  If not being secured, DHCPv6 is
   vulnerable to various attacks, particularly spoofing attacks.  This
   document analyzes the security issues of DHCPv6 and specifies a
   Secure DHCPv6 mechanism for communications between DHCPv6 clients and
   DHCPv6 servers.  This document provides a DHCPv6 client/server
   authentication mechanism based on server's public/private key pairs
   and client's certificates.  The DHCPv6 message exchanges are
   protected by the signature option and the timestamp option newly
   defined in this document.
