Abstract:
1. A method for an external device to gain access to a secure area of a resource, comprising: transmitting from the external device to the resource a signal that identifies the external device as capable of authentication; receiving by the external device from the resource an initiation of communication with the resource; responding by the external device to the initiation of communication by transmitting to the resource a listing of a plurality of authentication mechanisms that the external device is capable of performing, the authentication mechanisms each being a device for identifying an attribute of a user of the external device; receiving by the external device from the resource an indication of a particular combination of two or more authentication mechanisms selected from the listing of the plurality of authentication mechanisms is adequate to gain access to the secure area; receiving by the external device from the resource a first request for use of a first authentication mechanism selected from the listing of the plurality of authentication mechanisms; performing authentication using the first authentication mechanism at the external device; transmitting a first token from the external device to the resource, the first token representing a result of the first authentication mechanism; receiving by the external device from the resource another request for use of another authentication mechanism selected from the listing of the plurality of authentication mechanisms; performing authentication using the second authentication mechanism at the external device; repeating the transmitting a token step and receiving another request step until transmittal of the combination of authentication mechanisms is completed; and gaining access to the secure area in response to acceptance of the two or more of the tokens by the resource.
