Security Issues in Policy Routing

Routing mechanisms for inter-autonomousregion communication require distribution of policy-sensitive information as well as algorithms that operate on such information. Without such Policy Routing mechanisms, it is not possible for interconnected regions to retain their autonomy in setting and enforcing policy while still achieving desired connectivity. Thisproblem of interconnecting and navigating across autonomous regions is of inherent interest to the security community because the policies in question concern control of resource access and usage. Moreover, the security of the Policy Routing protocols themselves must be considered if they are to be applicable in sensitive environments. On the other hand, as usual, the security mechanisms take a toll in overall system complexity and performance. Most routing protocols, including proposed Policy Routing protocols [l], focus on environments where detection of an attack after it has taken place is sufficient. The purpose of this paper ...
