Jun Li, Chenghuai Lu, Weidong Larry Shi · 2004
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 network 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...
