The SeEDS project will implement a flexible, efficient and secure data space over the NDN architecture, offering self-sovereign, trustworthy, and privacy-preserving data sharing, while taking advantage of the advanced communication paradigms offered by the underlay NDN network. In particular, the SeEDS project will implement an ETSI compliant data space over the Named-Data Networking (NDN) ICN architecture. SeEDS will exploit the advanced capabilities of NDN to implement flexible and efficient data management and discovery, subscriptions to data events, as well as temporal data queries. At the same time, it will provide a trust management framework that will support in-network security and privacy operations, including data integrity verification and selective content revelation.
