A protocol for secure peer-to-peer communications is established based on existing cryptographic techniques and encryption algorithms. The peers (120, 130, 140) and a central security agent (110) undergo mutual authentication. A newly generated nonce is used for authentication, and a random session key is used for a session.

The keybar that is attached to the frame of a dynamoelectric machine is broken into a bald keybar with mini-dovetails attached to it. The bald keybar is identical to the bolt portion of a conventional keybar. The mini-dovetail is a trapezoidal or U-shaped strip with insulated slanted arms. The core packet is inserted loosely over an array of mini-dovetails. Devices such as wedges, threaded rods flex the slanted arm and press them against the slot faces of the core packet, thereby locking the core packet to the frame. Insulation on the slanted arms prevents large eddy currents due to shorted laminations, increasing the machine efficiency. Preventing large eddy currents also eliminates hot spots which could otherwise cause a core failure. Locking the core packets also prevents rattling of laminations. The locking method also distributes the torque forces evenly around the periphery.
