Abstract
A method and system for providing authentication of a user to a first peripheral device connected to a host computer using an authentication of the user on a second peripheral device, thereby allowing the user access to both devices through a single authentication. A security function on the second peripheral device is used to create an authorization phrase. Subsequent accesses to the first peripheral device requires the second peripheral device to re-create the same authorization phrase thereby demonstrating that the same second peripheral device is being used to access the first peripheral device and that a user was successfully authenticated to the second peripheral device. Other systems and methods are disclosed.
