Designing a routing protocol for large low-power and lossy networks
(LLNs), consisting of thousands of constrained nodes and unreliable
links, presents new challenges. The IPv6 Routing Protocol for Low-
power and Lossy Networks (RPL), have been developed by the IETF ROLL
Working Group as a preferred routing protocol to provide IPv6 routing
functionality in LLNs. Unfortunately, the currently available
security services in RPL will not protect against a compromised
internal node that can construct and disseminate fake messages.
Therefore, in RPL special security care must be taken when the
Destination Oriented Directed Acyclic Graph (DODAG) root is updating
the Version Number by which reconstruction of the routing topology
can be initiated. The same care also must be taken to prevent an
internal attacker (compromised DODAG node) to publish decreased Rank
value, which causes a large part of the DODAG to connect to the DODAG
root via the attacker and give it the ability to eavesdrop or
manipulate a large part of the network traffic. In this document, a
new security service is described that prevents any misbehaving DODAG
node from illegitimately increasing the Version Number or publish
illegitimately decreased Rank values.
