Claim:
1. A method of performing discovery, the method comprising: processing, at one or more integrated circuits in a first communication device and using a first hash function, at least a plurality of identifiers associated with a plurality of respective second communication devices to generate a first bit string, wherein the first bit string is indicative of whether each of the plurality of second communication devices is included in a group; causing, at the one or more integrated circuits, the first communication device to transmit the first bit string so that each second communication device can use the first bit string and the first hash function to determine whether the second communication device is included in the group; detecting, at the one or more integrated circuits, an indication that a new hash function should be used; in response to detecting the indication that a new hash function should be used, processing, at the one or more integrated circuits and using a second hash function different than the first hash function, at least the plurality of identifiers to generate a second bit string, wherein the second bit string is indicative of whether each of the plurality of second communication devices is included in the group; and causing, at the one or more integrated circuits, the first communication device to transmit the second bit string so that each second communication device can use the second bit string and the second hash function to determine whether the second communication device is included in the group.
