Abstract
A method for securing communications for a given network is provided. The method comprises by at least one node(i) of the network configured to utilize pairwise keys: generating a set of encryption keys; and transmitting the set of encryption keys to a controller for the network; by the controller, executing a key selection process wherein for each node(j) in the network an encryption key J is selected from the set of encryption keys; assigning the encryption key J to the node(j); and transmitting the selected encryption key J to the node(j); by each node(j), generating an encryption key I for the node(i); and sending the encryption key I to the node(i) via the controller.
