In an example embodiment, an apparatus comprising a transceiver configured to send and receive data and logic coupled to the transceiver. The logic is configured to determine from a signal received by the transceiver whether an associated device sending the signal supports a protocol for advertising available services. The logic is configured to send a request for available services from the associated device via the transceiver responsive to determining the associated device supports the protocol. The logic is configured to receive a response to the request via the transceiver, the response comprising at least one service advertisement and a signature. The logic is configured to validate the response by confirming the signature.
