US Patent 11695568 Virtualized network functions verification using decentralized identifiers

This disclosure describes techniques for verifying virtualized network functions (VNFs) using Decentralized Identifiers (DIDs). For example, a system includes an orchestrator configured to obtain, using a Decentralized Identifier (DID) that is associated with a virtualized network function (VNF) image for a VNF, a DID document associated with the DID, verify, based on the DID document associated with the DID, the VNF image, and deploy the VNF image as a VNF instance on a Network Functions Virtualization infrastructure (NFVi). The system also includes one or more consensus networks that store the DID document associated with the VNF image in a distributed ledger.
