OT: Good secure-ID solution? (Key FOB)

[Bryan Field-Elliot]

Hi,

I apologize for this being off topic, but while this has nothing to do with Struts, still I think this is a list where I might find knowledgable people with good info.

I'm looking for a good, cheap secure ID card or ID KeyFob solution, which I can integrate with my Struts application.

The device(s) are just cards or keychain devices, with an LCD display. The LCD display shows a 8-digit number, and this number changes to some other pseudo-random value every 60 seconds. It's a password, good for one minute. On the server side, you've got some code running which maps a username to a 60-second password (algorithmically), and authenticates the user thus.

RSA has great devices, and they're around $60 each which is fine with me. However, they want you to buy and run their server-side software as well. I'm not into that -- I'd just rather have a simple standardized algorithm and implement my own server-side checking (tied into my own database etc) within my Servlet classes, rather than run some 3rd party software on my server.

Does anyone know of such a thing?

Thanks,

Bryan
