1. A system comprising:
- a new network device;
a master network device in communication with a network, said master network device being configured to receive a request to join the network from the new network device and to issue a request to the new network device to perform a specified action verifiable to a user;
wherein the new network device is configured to present the specified action to the user; and
said master network device being further configured to receive verification from the user that the new network device performed the specified action and add the new network device to the existing network after receiving the verification from the user;
wherein said master network device includes a cryptographic key agreement protocol stored therein, said cryptographic key agreement protocol configured to generate a pair-wise encryption key for subsequent encrypted communication between the new network device and said master network device in response to said request to join the network;
wherein said master network device is configured to generate a different specified action from one new network device to the next; and
wherein said different specified action is a random specified action generated by said master network device.

Abstract
A system and method for adding a new network device to an existing network is described. An existing network has at least one master network device that acts as the gatekeeper for adding new network devices to the network. The master network device receives a request from a new network device to join the network. In response, the master network device issues a request to the new network device to perform a specified action. The master network device receives verification from the human user that the specified action has been performed. Upon receiving the verification, the master network device adds the new network device to the network.

9. A method comprising the steps of:
- receiving a request to join a network from a new network device;
requesting that the new network device perform a specified action verifiable by a user;
presenting the specified action to the user at the new network device;
verifying that the new network device has performed the action based upon an input received from the user at a master network device;
generating a pair-wise encryption key to be used by said master network device and the new network device for subsequent communications therebetween, said pair-wise encryption key being generated after the step of receiving said request to join the network from the new network device; and
adding the new network device to the network after receiving the input from the user;
wherein said specified action is different from one new network device to the next; and
wherein said specified action is randomly generated by said master network device from one new network device to the next. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
