In the IPv6 world, the IP protocol itself, i.e., IPv6, is used for a number of functions that currently fall beyond the scope of the IPv4 protocol. These functions include address configuration, neighbour detection, router discovery, and others. It is either suggested to or required that IPsec is used to secure these functions. Furthermore, IPsec is used to protect a number of functions that are considered dangerous in the IPv4 world, including mobility management and source routing. Now, the currently prominent method for creating IPsec Security Associations, the Internet Key Exchange (IKE) protocol, is both relatively heavy and requires that the underlying IP stacks are already fully functional, at least to the point that UDP may be used. As a result, the combination of the widened responsibility of IPsec and the relative heavy weight of IKE creates a vicious cycle that is a potential source of various denial-of-service attacks. Additionally, if we want to use IPsec to secure IPv6 autoconfiguration, a chicken-and-egg problem is created: fully configured IPsec is needed to configure IP, and fully configured IP is needed to configure IPsec. In this paper, we describe these problems in detail.
