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.
