  Digitalization affects all industrial domains and causes disruption of
various business models. Especially in domains such as logistics and
manufacturing, inter-connected devices and near-realtime exchange of sensor
data across enterprises allows to speed up processes, reduce costs and respond
to customer's needs. However, the advent of the Industrial Internet of Things
(IIoT) also raises challenges with respect to security and privacy of sensitive
and personal data that is created by sensors and processed by services hosted
in different administrative domains. The Industrial Data Space initiative
addresses these challenges and proposes a secure edge gateway platform named
"Trusted Connector". In this report, we introduce the main security building
blocks of the Trusted Connector and point out how they help protecting
business-critical data and preserving the user's privacy.
