Abstract
The RIPE database specifications and RPSL define languages used as
the basis for representing information in a routing policy system. A
repository for routing policy system information is known as a
routing registry. A routing registry provides a means of exchanging
information needed to address many issues of importance to the
operation of the Internet. The implementation and deployment of a
routing policy system must maintain some degree of integrity to be of
any use. The Routing Policy System Security RFC [3] addresses the
need to assure integrity of the data by proposing an authentication
and authorization model. This document addresses the need to
distribute data over multiple repositories and delegate authority for
data subsets to other repositories without compromising the
authorization model established in Routing Policy System Security
RFC.
