An Efficient Architecture for Trust Management in IoE Based Systems of Systems

Internet of Every things (IoE) is a network that integrates a variety of heterogeneous nodes, such as connected portable devices, connected cars, smart home appliances, humans, etc. to Internet. The constituents of IoE are heterogeneous, distributed by nature and also autonomous in most of cases, which meet the criteria of what we call Systems of Systems (SoS). These smart objects communicate and collaborate between each other in dynamic environments which are subject to several security attacks. In this paper, we propose a hierarchical based blockchain trust management architecture with mobility support in highly distributed IoE based Systems of Systems. This architecture deals efficiently with scalability issues. It allows smart objects to disseminate the trustworthiness of the service providers they interact with them to the blockchain. This later makes the access to this information possible from anywhere and ensures a global view of trustworthiness information. Thanks to the blockchain technology, our architecture outperforms the existing trust management solutions especially in terms of scalability and mobility support.
