RSA SecurID Debug Connectors

The debug connector consists of a six-pin port that speaks a protocol vaguely like JTAG. As the RST pin is low by default, you can reset the device by temporarily making it high voltage. The following procedure will do the trick, using a 3V battery and a bit of wire. All soldering is optional, and no GoodFET is required.

 

1) Solder the negative connector of a 3V battery to the lone debug pin.

2) Touch the positive connector to each debugging pin, one at a time. I think that I've marked the correct pin above, but my memory is rather foggy.

3) The screen should flash, then numbers will blink every 60 seconds as when the token was active.

4) A reset expired unit can be distinguished from an unexpired unit by the 3 symbol, which remains on the bottom-right corner of the LCD. This symbol is not shown on a unit which has not yet expired.
