Abstract
Existing Internet of Things architectures rely on middleware (cloud services) to host coordination logic among devices. This middleware is based on Event Based Systems where the Broker architecture and the Publish/Subscribe design pattern are used to deal with heterogeneous environments and for decoupling purposes, being the MQTT protocol one of the most extensively used Event Based Systems for Internet of Things Solutions.
Two prominent security issues in these type middleware are: possible network interruptions between devices and the middleware, and potentially compromised devices. This thesis proposes Scoping and Execution Monitoring in Event Based Systems to cope with possible network disconnections, and to deal with misbehavior of faulty or compromised devices. I define a mathematical model for Event Based Systems where the interplay between Scoping and Execution monitoring is formalized, and empirically evaluate the performance of these security mechanisms.
