6. Securing Broker-Less Publish/Subscribe Systems Using
Identity-Based Encryption

7. Abstract
The provisioning of basic security mechanisms such as authentication and
confidentiality is highly challenging in a content-based publish/subscribe system.
Authentication of publishers and subscribers is difficult to achieve due to the loose
coupling of publishers and subscribers. Likewise, confidentiality of events and
subscriptions conflicts with content-based routing. This paper presents a novel
approach to provide confidentiality and authentication in a broker-less content-based
publish/subscribe system. The authentication of publishers and subscribers as well as
confidentiality of events is ensured, by adapting the pairing-based cryptography
mechanisms, to the needs of a publish/subscribe system. Furthermore, an algorithm to
cluster subscribers according to their subscriptions preserves a weak notion of
subscription confidentiality. In addition to our previous work , this paper contributes 1)
use of searchable encryption to enable efficient routing of encrypted events, 2)
multicredential routing a new event dissemination strategy to strengthen the weak
subscription confidentiality, and 3) thorough analysis of different attacks on
subscription confidentiality. The overall approach provides fine-grained key
management and the cost for encryption, decryption, and routing is in the order of
subscribed attributes. Moreover, the evaluations show that providing security is
affordable w.r.t. 1) throughput of the proposed cryptographic primitives, and 2) delays
incurred during the construction of the publish/subscribe overlay and the event
dissemination.
