Abstract:
1. An apparatus, comprising: a transceiver; and logic in communication with the transceiver; wherein the logic is configured to receive data corresponding to keying material derived from a symmetric key generation system for a plurality of predefined groups; wherein the logic is responsive to a signal received from an associated device via the transceiver indicating the associated device is a member of a first set of groups in common with the plurality of predefined groups to communicate with the associated device via the transceiver to select, together with the associated device, a selected group from the first set of groups as agreed between the apparatus and the associated device, and to generate a session key based on data corresponding to keying material for the selected group, an identifier of the associated device, and a parameter identifying the associated device as an initiator of a connection between the associated device and the apparatus; wherein the logic is configured to authenticate the associated device by communicating to the associated device, via the transceiver, a parameter identifying the apparatus as a target of the connection between the associated device and the apparatus and determining that the associated device possesses the session key.
