Asset authentication in a dynamic, proximity-based network of communication devices, each having a first interface for establishing the dynamic, proximity-based network by short-range wireless beacon broadcast messaging, and a second interface for communicating with a server by broadband communication. A first communication device sends (210) via the first interface an authentication request to a second communication device having an associated asset. The second device receives (220) the authentication request via the first interface and in response communicates (230) with the server via the second interface to generate a digital signature by encrypting data which includes the asset with a private key for the second device. The second device sends (240) a signing completed report message about the generation of the digital signature to the first device via the first interface. The first device receives (250) the signing completed report message via the first interface and in response communicates (260) with the server via the second interface to retrieve an authentication result. |
