Abstract: According to one embodiment, techniques are provided to enable secure communication among devices in a mesh network using a group temporal key. An authenticator device associated with a mesh network stores a pairwise master key for each of a plurality of devices in a mesh network upon authentication of the respective devices. Using the pairwise master key, the authenticator device initiates a handshake procedure with a particular device in the mesh network to mutually derive a pairwise temporal key from the pairwise master key. The authenticator device encrypts and signs a group temporal key using the pairwise temporal key for the particular device and sends the group temporal key encrypted and signed with the pairwise temporal key to the particular device.

Abstract: Techniques are provided to facilitate monitoring of utility application traffic streams. At a network device that routes utility application traffic for utility devices, control information is received, where the control information is configured to cause the network device to monitor utility application traffic that passes through the network device. The network device monitors a header inserted into utility application traffic messages based on the control information.
