A Distributed Tabling Algorithm for Rule Based Policy Systems.
Abstract
Distributed Peer-to-Peer and Grid infrastructure require
distributed access control mechanisms. These mechanisms can be implemented
in distributed trust management infrastructures and usually require
reasoning on more than one peer, as soon as authority is delegated or
requests involve several authorities. Building on previous work of the
authors which formalized such a distributed trust management
infrastructure based on distributed logic programs, we describe in this
paper how reasoning can be implemented as distributed logic evaluation and
how loops during this evaluation can be handled with. Our solution is
based on a loop tolerant distributed tabling algorithm which includes in
the process protection of sensitive policies and generation of proofs
without increasing the complexity of the system.
