A method for operating a seeker device includes generating a first seeker truncated hash output from a sought service name, and generating a second seeker truncated hash output from the sought service name, wherein the first seeker truncated hash output and the second seeker truncated hash output are uncorrelated. The method also includes transmitting a first request message including the first seeker truncated hash output, and receiving a first response message from an advertiser device, the first response message including a second advertiser truncated hash output generated from an advertised service name, wherein the first seeker truncated hash output matches a first advertiser truncated hash output generated from the advertised service name. |

1. A method for operating a seeker device, the method comprising:
combining, by the seeker device, a first value and a first service name of a first service sought by the seeker device, thereby producing a first modified service name; hashing, by the seeker device, the first modified service name using a hash function, thereby producing a first hash output; truncating, by the seeker device, a first pre-specified portion of the first hash output, thereby producing a first truncated hash output; combining, by the seeker device, a second value and the first service name of the first service, wherein the second value is not equal to the first value, thereby producing a second modified service name; hashing, by the seeker device, the second modified service name using the hash function, thereby producing a second hash output; truncating, by the seeker device, a second pre-specified portion of the second hash output, thereby producing a second truncated hash output; transmitting, by the seeker device, a request message requesting service information of the first service, the request message including the first truncated hash output; receiving, by the seeker device, a response message from an advertiser device including service information of a second service advertised by the advertiser device and a third truncated hash output, the third truncated hash output associated with a second service name of the second service; and determining, by the seeker device, that the first service is found and the received service information is related to the service information of the first service in response to determining that the second truncated hash output and the third truncated hash output are equal. |
