Abstract
Content-based publish-subscribe is an efficient communication paradigm
that supports dynamic, many-to-many data dissemination in a distributed
environment. A publish-subscribe system deployed over a wide-area net-
work must handle information dissemination across distinct authoritative
domains and heterogeneous platforms. Such an environment raises serious
security concerns. This paper describes a practical scheme that preserves
confidentiality against eavesdroppers for private content-based publish-subscribe
systems over public networks. In this scheme, publications and subscriptions are encrypted, while the publish-subscribe infrastructure is able to
make correct routing decisions based on encrypted publications and subscriptions. Plaintexts are not revealed in the infrastructure for the purpose
of security and efficiency. This scheme efficiently supports interval-matching
as a predicate function for subscriptions. The security of this scheme is analyzed, and further improved by several techniques.
