Abstract:
In embodiments of virtual addressing for mesh networks, a node in a mesh network publishes packets and/or subscribes to packets using a virtual address that is derived from a unique identifier. The unique identifier has a larger address space than the destination address field of the packet. The unique identifier and an application key are hashed to elide the unique identifier from the destination address that is transmitted in the packet over the mesh network. A node receiving the packet can determine that the address is a virtual address, and disambiguate the destination address to determine that the virtual address corresponds to a unique identifier known to the receiving node.

Claim (Index 14):
A method of virtual addressing in a mesh network by a source node, the method comprising:\n hashing, by the source node, a unique identifier (UID) to form a UID hash; generating a key identifier that identifies an encryption key associated with the UID; setting an address type indicator to indicate that a destination address is a virtual address; forming the virtual address including concatenating the address type indicator and a portion of the UID hash; inserting the virtual address in a destination address field of a header of a packet; and transmitting the packet over the mesh network to a destination node, the transmitting directing the destination mesh network device to:\n determine that the address type indicator indicates that the destination address in the destination address field of the packet includes the virtual address; \n disambiguate the virtual address in the received packet, the disambiguation using the UID to determine that the virtual address corresponds to a known UID that is provisioned to the destination node; and \n authenticate a packet payload using the UID as additional data.
