Abstract: Connected devices of IoT platforms are known to produce, process and exchange vast amounts of data, most of it sensitive or personal, that need to be protected. However, achieving minimal data protection requirements such as confidentiality, integrity, availability and non-repudiation in IoT platforms is a non-trivial issue. For one reason, the trillions of interacting devices provide larger attack surfaces. Secondly, high levels of personal and private data sharing in this ubiquitous and heterogeneous environment require more stringent protection. Additionally, whilst interoperability fuels innovation through cross-platform data flow, data ownership is a concern. This calls for categorizing data and providing different levels of access control to users known as global and local scopes. These issues present new and unique security considerations in IoT products and services that need to be addressed to enable wide adoption of the IoT paradigm. This thesis presents a security and privacy framework for the Web of IoT platforms that addresses end-to-end security and privacy needs of the platforms. It categorizes platforms’ resources into different levels of security requirements and provides appropriate access control mechanisms.
