Network filtering with private resolvable addresses

A method of address filtering of an advertising extension packet by a destination node in a wireless network, the method comprising the destination node:

• receiving the advertising extension packet from a source node in the wireless network;
• generating a first local hash value based on a value of a random number field included in the received advertising extension packet and a first local filtering identity resolving key;
• comparing the first local hash value to a hash value included in the advertising extension packet to determine if the first local hash value matches the hash value included in the advertising extension packet;
• and
• responsive to the first local hash value matching the hash value included in the advertising extension packet, receiving a protocol data unit on a data channel and at a time indicated in the advertising extension packet.

A wireless network device comprising:

• a wireless network interface;
• a processor;
• and
• a memory comprising instructions for an addressing application executable by the processor to configure the wireless network device to:
• hash a filter key and address-generation input data, using a Cipher-based Message Authentication Code, to produce an identity resolving key;
• hash the identity resolving key and a value of a random number field to generate an address hash, the identity resolving key being cryptographically-derived from address-generation input data;
• form an advertisement address, the advertisement address including a portion of the address hash;
• insert the advertisement address in an advertising extension packet;
• and
• transmit the advertising extension packet over the wireless network, the address hash being usable by a destination node to filter the advertising extension packet.
