Build your own dongle
I found this design project on Amtel AVR 2004 design contest web site.

Intelligent Security Serial Dongle
The ATmega8L-8AI microprocessor-based Intelligent Security Serial Dongle effectively restricts access to a computer or embedded system. The low-cost design uses an MD5-based challenge-response authentication procedure augmented by a random number generator. No external power source is needed.
