ABSTRACT:
In a communication system in which a node may communicate over insecure channels with any of a plurality of terminals and may pass messages from any of the terminals to any other of the terminals, communication is secured by computing a first cryptovariable from information associated with certificates exchanged between the node and a terminal, computing a second cryptovariable from a prior-art public key exchange, and computing a session cryptovariable as a function of the first and second cryptovariables. This can be done asymmetrically, enabling a terminal to verify the security of an unattended node.
