Technical Summary
In recent times, networked electronic devices have found an
increasing number of applications in various fields. Yet, for
reasons ranging from operational application to economics, these
wired and wireless devices are often supplied with minimum physical
resources; the constraints include those on computational resources
(RAM, clock speed, storage), communication resources (duty cycle,
packet size, etc.), but also form factors that may rule out user
access interface (e.g., the housing of a small stick-on switch), or
simply safety considerations (e.g., with gas meters). As a
consequence, the resulting networks are more prone to loss of traffic
and other vulnerabilities. The proliferation of these low power and
lossy networks (LLNs), however, are drawing efforts to examine and
address their potential networking challenges. Securing the
establishment and maintenance of network connectivity among these
deployed devices becomes one of these key challenges.
This document presents a framework for securing Routing Over LLNs
(ROLL) through an analysis that starts from the routing basics. The
objective is two-fold. First, the framework will be used to identify
pertinent security issues. Second, it will facilitate both the
assessment of a protocol's security threats and the identification of
the necessary features for development of secure protocols for the
ROLL Working Group.
The approach adopted in this effort proceeds in four steps, to
examine security issues in ROLL, to analyze threats and attacks, to
consider the countermeasures, and then to make recommendations for
securing ROLL. The basis is found on identifying the assets and
points of access of routing and evaluating their security needs based
on the Confidentiality, Integrity, and Availability (CIA) model in
the context of LLN. The utility of this framework is demonstrated
with an application to IPv6 Routing Protocol for Low Power and Lossy
Networks (RPL).
