Apparatus, system, and method of peer-to-peer (P2P) communication

A product comprising one or more tangible computer-readable non-transitory storage media comprising instructions operable to, when executed by at least one processor, enable the at least one processor to cause a first wireless communication device to:

• determine a negotiated bootstrapping mechanism from a plurality of bootstrapping mechanisms based on a first message-exchange with a second wireless communication device, the first message-exchange comprises a first Peer-to-Peer (P2P) frame from the first wireless communication device and a second P2P frame from the second wireless communication device, the first P2P frame comprises first supported bootstrapping functionality information to indicate one or more first bootstrapping functionalities supported by the first wireless communication device, the second P2P frame comprises second supported bootstrapping functionality information to indicate one or more second bootstrapping functionalities supported by the second wireless communication device;
• after determination of the negotiated bootstrapping mechanism, pair the first wireless communication device with the second wireless communication device according to the negotiated bootstrapping mechanism;
• derive a Pairwise Master Key Security Association (PMKSA) based on a second message-exchange with the second wireless communication device after pairing with the second wireless communication device;
• and
• determine an encryption key according to a third message exchange with the second wireless communication device based on the PMKSA, the encryption key configured to encrypt a P2P communication with the second wireless communication device.
