Abstract

There is disclosed a user authentication device for issuing authentication information. The user authentication device comprising a photovoltaic panel configured such that the photovoltaic panel can assist in powering the device in response to the device being exposed to the light.

First claim

What is claimed is:

1. A processorless user authentication device, comprising:
a chargeable device;
a photovoltaic panel for charging the chargeable device, wherein the photovoltaic panel is arranged such that the chargeable device is charged when the photovoltaic panel is exposed to light;
an input mechanism for facilitating the release of charge from the chargeable device;
a non-volatile memory including a pre-produced sequence of one-time passwords;
a circuit board constructed and arranged for indexing into the non-volatile memory of the hardware device upon a request for a one-time password to read the one-time password; and
an output device constructed and arranged to output a read one-time password, wherein the output device comprises a display for displaying one-time passwords;
characterized in that indexing includes dividing a numeric value used for indexing by a number of one-time password elements in the non-volatile memory, using the result as the offset to read a first one-time password from the non-volatile memory, using the remainder of the division as an offset to read a second one-time password from the non-volatile memory, and exclusive-oring the first one-time password and the second one-time password to produce the one-time password.

2. The processorless user authentication device as claimed in claim 1 , wherein the photovoltaic panel is provided on an outer surface of the processorless user authentication device.

3. The processorless user authentication device as claimed in claim 2 , wherein the photovoltaic panel is formed integrally with the outer surface of the processorless user authentication device.

4. The processorless user authentication device as claimed in claim 1 , wherein the photovoltaic panel comprises a plurality of photovoltaic cells.

5. The processorless user authentication device as claimed in claim 1 , wherein the chargeable device comprises a capacitor that is connected to the photovoltaic panel.

6. The processorless user authentication device as claimed in claim 5 , wherein the input mechanism comprises a button and an associated switch that when actuated releases the charge from the capacitor.

7. The processorless user authentication device as claimed in claim 1 , wherein the pre-produced sequence of one-time passwords are generated on a processing system external to the processorless user authentication device and stored on the processorless user authentication device.

8. The processorless user authentication device as claimed in claim 1 , wherein the processorless user authentication device is configured for authenticating a user in an authentication system for enabling access to an access-controlled resource.

9. A user authentication system, comprising:
the processorless user authentication device as claimed in claim 1 ;
a communications terminal configured for communicating with the processorless user authentication device; and
a verifier configured for communicating with the communications terminal and authenticating a user.
