Techniques for a secure device registration and software update using Decentralized Identifiers (DIDs). For example, a method includes sending, by a device and to a data store, a request for a software update published by a software publisher, wherein the request includes a verifiable credential for the device including a DID of the device; receiving, by the device and from the data store, a verifiable credential for the software update, wherein the verifiable credential includes a DID of the software publisher; determining, by the device, whether the software update is newer than software on the device; obtaining, by the device, the software update from the software publisher from a location specified by the verifiable credential; verifying, by the device, the software update based on the verifiable credential; and in response to verifying the software update based on the verifiable credential, installing, by the device, the software update.
