                     Secure DHCPv6 with Public Key
                       draft-ietf-dhc-sedhcpv6-03

Abstract

   The Dynamic Host Configuration Protocol for IPv6 (DHCPv6) enables
   DHCPv6 servers to pass configuration parameters.  It offers
   configuration flexibility.  If not 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 communication between DHCPv6 clients and DHCPv6
   servers.  This mechanism is based on public/private key pairs.  The
   authority of the sender may depend on either pre-configuration
   mechanism or Public Key Infrastructure.
