Abstract
In a method for enabling devices to communicate securely, a first device dynamically generates a human body nonce (HBN) and then sends that HBN to a second device via a human body communication conduit (HBCC). After sending the HBN from the first device to the second device, the first device uses the HBN to establish security for an over-the-air (OTA) communication session between the first device and the second device. For instance, the first device may derive a key, based at least in part on the HBN, and the first device may use the key to encrypt communications to be sent OTA between the first device and the second device. Other embodiments are described and claimed.
