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.

Abstract: Embodiments are directed to enrollment of an endpoint device in a secure domain. An enrollment request is sent to a delegated registrar (DR) device to initiate a trust-establishment procedure with the DR device to establish initial connectivity and an initial symmetric key to be shared between the DR and the endpoint device. The DR device provides to the endpoint device limited-use credentials for group-access key establishment, and group connectivity parameters for accessing a group administrator (GA) device. The endpoint device and the GA device perform a group-enrollment procedure in which the endpoint device provides the limited-use credentials to the GA device and receives, from the GA device, the group-access key.

Abstract: In one embodiment, a computing device includes at least one hardware processor to execute instructions, a network interface to enable communication with a second computing device and a third computing device, and at least one storage medium. Such medium may store instructions that when executed by the computing device enable the computing device to request delegation of a key provisioning privilege for the second computing device from the third computing device via a parent-guardian delegation protocol comprising a three-party key distribution protocol with the second computing device and the third computing device, the three-party key distribution protocol having interposed therein a two-party authenticated key exchange protocol between the computing device and the third computing device. Other embodiments are described and claimed.
