Abstract:
The default method for IPv6 address generation uses an
Organizationally Unique Identifier (OUI) assigned by the IEEE
Standards Association and an Extension Identifier assigned to the
hardware manufacturer [1] (section 2.5.1 RFC-4291) [RFC4291]. This
fact thus means that a node will always have the same Interface ID
(IID) whenever it connects to a new network. Because the node's IP
address does not change, the node will be vulnerable to privacy
related attacks. Currently this problem is addressed by the use of
two mechanisms that do not make use of the MAC address, or other
unique values that can be used for ID generation, for randomizing the
IID; Cryptographically Generated Addresses (CGA) [RFC3972] and
Privacy Extension [RFC4941]. The problem with the former approach is
the computational cost involved for the IID generation and in the
verification process. The problem with the latter approach is that it
lacks necessary security mechanisms and provides the node with only
partial protection against privacy related attacks. This document
proposes the use of a new algorithm for use in the generation of the
IID while, at the same time, securing the node against some types of
attack, like IP spoofing. These attacks are prevented by the addition
of a signature to messages sent over the network and by finding a
binding with the nodes' IP address and its public key. The use of
theResource Public Key Infrastructure (RPKI), introduced in this
document, is based on the centralized version explained in RFC 6494
and RFC 6495.
