POSTER: Using Verifiable Credentials for Authentication of UAVs in Logistics

Verifiable Credentials (VCs) have been widely adopted as a format for asserting information through use of digital signature technique, and offer versatile usages. The World Wide Web Consortium (W3C) has standardized the data model for VCs [1], and the motivation for this study is to verify the applicability of its data model through a concrete, realistic scenario. For verification, we have chosen a scenario where Unmanned Aerial Vehicles (UAVs) collaborate to deliver packages. As a contribution of this study, we demonstrate how we can selectively disclose attributes of UAVs yet ensure its mission under an authorized contract. Furthermore, we propose a method for issuing receipts through use of VCs and Verifiable Presentations (VPs) that guarantees completion of delivery while UAVs remain anonymous. For this function, we developed a new format for VP, namely 'VP with Message.' These features have been implemented through a demo application.
