A Framework for Secure End-to-End Delivery of Messages in Publish/Subscribe Systems

Abstract

In this paper, we present a framework for the secure end-to-end delivery of messages in distributed messaging infrastructures based on the publish/subscribe paradigm. The framework enables authorized publishing and consumption of messages. Brokers, which constitute individual nodes within the messaging infrastructure, also ensure that the dissemination of content is enabled only for authorized entities. The framework includes strategies to cope with attack scenarios such as denial of service attacks and replay attacks. Finally, we include experimental results from our implementation
