Security of Wi-Fi Direct

As mentioned earlier, Wi-Fi Direct will support the latest encryption: WPA2 (AES-CCMP). It isn't totally clear yet, but it's likely that the Enterprise (RADIUS/EAP) mode won't be included, only the Pre-Shared Key (PSK) mode.

The PSK mode is susceptible to brute-force dictionary attacks on the PSK or encryption passphrase. To be fully secure, users must use a long and complex passphrase. However, Wi-Fi Direct might automatically create these passphrases, so it may not even be a concern.
