SOFIE - Secure Open Federation for Internet Everywhere

Project description

Piecing together the IoT puzzle

There is a growing need for standardisation and interoperability among Internet of Things (IoT) platforms, devices and systems. The current fragmentation is visible in the numerous proprietary technologies, protocols and communication standards. It is a situation that hinders the potential of IoT, limiting its scalability, efficiency and innovation. In this context, the EU-funded SOFIE project will propose a game changing solution. By creating a secure and open IoT federation architecture, it leverages distributed ledger technology to enable unlimited scalability, smart contracts, and decentralised solutions. Any IoT platform can effortlessly join the federation, maintaining data within their respective platforms. SOFIE will build on existing open standards and craft an IoT federation framework that fosters secure and decentralised business platforms.


SOFIE addresses the challenges of the call by creating a secure and open IoT federation architecture and framework. We use Distributed Ledger Technology (DLT), including blockchains and inter-ledger technologies, to enable actuation, auditability, smart contracts and management of identities and encryption keys, and to enable totally decentralised solutions with virtually unlimited scalability.
We address the fragmentation of IoT through federation rather than integration. Virtually any IoT platform can join the federation by creating, relatively simply, an adapter. Data remains in the respective IoT platforms and is usable by all the applications within the limits set by the applicable security and privacy policies.
We exercise security and privacy by design. We provide end-to-end security, key management, authorisation, accountability, and auditability, utilising DLTs where applicable. The user shall retain control over their data also after the data have been stored in the Cloud or Fog in an EU GDPR (or other regulations) compliant manner.
We base our work on existing open standards, interfaces and components, such as FIWARE, W3C Web of Things (WoT), and oneM2M. We will select existing components, develop new ones, and collect them — together with documentation, instructions and examples — into an IoT federation framework for creating administratively decentralised, open, and secure IoT business platforms from existing IoT platforms.
We will demonstrate the practicality of our approach by using it in three pilots in three different sectors: food chain, gaming, and energy market. Three business platforms will be realised for the pilots. The results of the pilots will be evaluated against the key performance indicators.
We actively participate in standardisation and disseminate our results through scientific journals, conferences, and workshops, but also the Web, social media and developer communities. We also aim to make at least two of the pilots sustainable.
