Distributed Multi-Attribute Anonymous Certificate Management Scheme With Fine-Grained Revocation for Uncrewed Aerial Vehicles

- Record updated
Summary
This paper proposes a distributed multi-attribute anonymous certificate management scheme for uncrewed aerial vehicles (UAVs), which need certificates carrying multiple attributes as proof of mission authorization. It combines redactable signatures and dynamic accumulators to allow selective disclosure and fine-grained revocation of individual attributes within one certificate. It also uses a distributed key-generation mechanism so certificates can be issued in a decentralized way, avoiding the need to apply to separate centralized authorities for cross-regional access.
