Secure DHCPv6
draft-ietf-dhc-sedhcpv6-21
Abstract
DHCPv6 includes no deployable security mechanism that can protect
end-to-end communication between DHCP clients and servers. This
document describes a mechanism for using public key cryptography to
provide such security. The mechanism provides encryption in all
cases, and can be used for authentication based on pre-sharing of
authorized certificates.
