Abstract
Key exchanges between peer-to-peer devices can be vulnerable to man in the middle attacks. Verification of the key exchanges can be made on a channel, network and/or device different from the channel, network and/or device used for the key exchange to determine whether the key exchange was secure. Verification of the key exchange can also be made through an established and trusted device and/or entity. If the key exchange was secure, the parties to a communication utilizing the key(s) exchanged can be notified, if desired. If the key exchange was not secure, the parties can be notified and the communication can be selectively disconnected.
