I remember seeing some discussion about the security gadgets
people from Bell Labs, amonst others, used for logging in from
remote sites. It was a s imple credit-card-calculator-like
challenge-response device. Any pointers?
Sure...
We use either an AT&T smart card or the Digital Pathways Securenet
Key. We started using the latter because they don't sell (expensive)
host software, so they'll disclose the information you need to roll
your own host end software. A list of some other authenticator vendors
can be found in

Btw -- the comment in there about the Securenet Key not being exportable
from the U.S. is wrong, even though it does use DES. It's an authentication
device not readily usable for secrecy, so our beloved government
has deigned to permit its sale to furriners.
