For the delivery of the Smart Meter Gateway a special secure supply chain is required in Germany. The goal of the secure supply chain is to avoid and detect any manipulation in the delivery process – from production to the place of installation. PPCs secure supply chain is based on stable, reusable transport boxes with a special locking system. These boxes are opened and closed using an individual electronic key and special codes that are generated in a web portal. As pioneers of the secure supply chain, we have already gathered valuable practical experience that we share in our courses.
