Abstract
A method for authentication of a computing device so that shares of a secret may be delivered, over a network that uses a communications protocol which does not require use of an address, and on which an authentication server is listening, comprising the steps of dividing the secret into a first share and a second share, or more; destroying the secret; transmitting the second share, together with a unique identifier, out of band to a pre-designated location; erasing the second share from the computing device; storing the first share at the computing device; broadcasting the unique identifier over the network; accepting a request over the network from an authentication server to initiate an authentication protocol; responding to the request; receiving the second share from the authentication server; and reconstructing the secret using the received second share and the stored first share.
