1. A method, comprising:
receiving, by an apparatus, a service discovery frame from a wireless device operating synchronously with the apparatus in a neighbor awareness network cluster, the service discovery frame including one or more scrambled values associated with one or more service names, each of the scrambled values being a hash of an argument comprising the service name and a component value selected based on a current synchronous time shared by the apparatus and the wireless device; comparing, by the apparatus, the one or more received scrambled values with scrambled values associated with service names maintained by the apparatus, each of the scrambled values maintained by the apparatus being a hash of an argument comprising a valid service name of a service known by the apparatus and a component value that is selected by the apparatus based on the current synchronous time shared by the apparatus and the wireless device; and determining, by the apparatus, that the received one or more scrambled values are associated with a service name known by the apparatus, if any of the received scrambled values satisfies the comparison with a scrambled value maintained by the apparatus, associated with the service name. |
