Abstract
A method for secure exchange of password information between a requester node and a server node using a verification protocol for confirming the identification of the requester node by the server in the presence of eavesdroppers is disclosed. By adjusting the parameters of the protocol the possibility that an intercepter of the exchanges can impersonate a requester node after receiving a specified number of exchanges may be engineered to satisfy security objectives.
