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 1):
A method of virtual addressing in a mesh network by a mesh network device implemented as a sensor node, the method comprising:\n hashing a unique identifier (UID) to form a UID hash by hashing the UID and a virtual address salt using a Cipher-based Message Authentication Code (CMAC) to generate the UID hash, the UID being associated with an application; generating a key identifier, which identifies an application key that is associated with the application, by hashing the application key and a key-identifier salt using the CMAC to produce a first hash result, and hashing the first hash result and a virtual address key salt using the CMAC; and forming a virtual address including concatenating an 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; inserting a sensor reading in an application payload field in the packet; and transmitting the packet over the mesh network.
