Claim Text:
1. A method, comprising: transmitting, by an apparatus, wireless device discovery messages including a nonce for authenticating wireless devices responding to the wireless device discovery messages; receiving, by the apparatus, a wireless response message from another wireless device responding to the wireless device discovery messages, the wireless response message including an authentication test value based on the nonce; authenticating, by the apparatus, the other wireless device, without establishing a wireless connection to the other wireless device, if the authentication test value is valid; wherein the authentication test value received from the other wireless device is a received value of a combination of the nonce and a secret value shared by the wireless device and the other wireless device; wherein the authenticating further comprises: computing, by the apparatus, an authentication test value based on the nonce and the shared secret value; comparing, by the apparatus, the computed authentication test value with the received authentication test value; and authenticating, by the apparatus, the other wireless device, if the computed authentication test value compares with the received authentication test value.
