Existing publish-subscribe systems focus on functionality and routing and does not provide any guarantee in terms of security and fault tolerance. This work extends a particular publish-subscribe system, REDS (REconfigurable Dispatching System), adding specific mechanisms to provide resilience.
Security is provided through the concepts of secure path and access control. Fault tolerance is guaranteed increasing the number of links connecting two neighbors. Using these concepts, we illustrate the new architecture of REDS, called SEC-REDS, in which we have added new components, like the Security Manager and the Backup Connections Manager
