USB hub keypad
First Claim
1. A method for securing a token from unauthorized use, comprising:
- intercepting by a hub a first message from the host processing device addressed to the token in the hub;
providing by the hub the intercepted message to a PIN entry device communicatively coupled to the hub, the PIN entry device being different from a keyboard associated with the host processing device;
accepting by the hub a second message from the PIN entry device comprising a user-entered PIN;
generating by the hub a third message from the second message, the third message comprising the user-entered PIN and at least a portion of the first message; and
transmitting the third message from the USB-compliant hub to the token.

Abstract
A method and apparatus for securing a token from unauthorized use is disclosed. The method comprises the steps of receiving a first message transmitted from a host processing device and addressed to a PIN entry device according to a universal serial bus (USB) protocol; accepting a PIN entered into the PIN entry device; and transmitting a second message comprising at least a portion of the first message and the PIN from the PIN entry device to the token along a secure communication path. In another embodiment, the present invention describes an apparatus for securing a token from unauthorized use, comprising a PIN entry device, communicably coupleable to a host processing device transmitting a first message addressed to the PIN entry device, and communicatively coupleable to the token according to a universal serial bus USB protocol, the PIN entry device comprising a user input device, for accepting a user-input PIN; and a processor, communicatively coupled to the user input device, the processor for receiving the first message and combining the first message with the user-input PIN, and for producing a second message having at least a portion of the first message and the user-input PIN.
