Abstract:
1. A method of authenticating a communications session between two or more user communications devices over a plurality of communications channels comprising: creating a first set of signatures by the first user communications device, wherein the first set of signatures comprises a unique signature for each of a plurality of communications channels; communicating one of said first set of signatures to a second user communications device comprising a first authentication module over one of said plurality of communications channels, wherein the first authentication module of said second user communications device retrieves a verification key from local storage and authenticates the first user communications device's signature associated with the one of said plurality of communications channels using the retrieved verification key; accepting communication with the first user communications device only if the first user communications device's signature is successfully authenticated by said first authentication module; communicating, only if a second of the plurality of communications channels are required, a second of said first set of signatures to the second user communications device over a second of said plurality of communications channels, wherein the first authentication module of said second user communications device retrieves a verification key from local storage and authenticates the first user communications device's second signature using the retrieved verification key; and accepting communication with the first user communications device over the second communications channel only if the second signature is successfully authenticated by said first authentication module.
