Abstract:
1. A controller for calculating group keys used to secure communications to a plurality of remote devices in a network, wherein the plurality of remote devices are configured in a mesh topology, the controller comprising: a key logic implemented, at least in part, in hardware, wherein the key logic is configured to calculate a first group key by using a group master key, and (ii) and information that comprises a unique identifier that uniquely corresponds to a first remote device of the plurality of remote devices, wherein the first group key is a key for communicating to the first remote device and wherein communications received from the first remote device are encrypted with a different second group key; and a communication logic configured to secure a communication by using the first group key, wherein the communication is to be transmitted to the first remote device and wherein the first group key is distinct from the second group key.
