Abstract
Adequate user authentication is a persistent problem, particularly with mobile
devices such as Personal Digital Assistants (PDAs), which tend to be highly
personal and at the fringes of an organization's influence. Yet these devices are
being used increasingly in military and government agencies, hospitals, and
other business settings, where they pose a risk to security and privacy, not only
from sensitive information they may contain, but also from the means they
typically offer to access such information over wireless networks. User
authentication is the first line of defence for a mobile device that falls into the
hands of an unauthorized individual. However, motivating users to enable
simple PIN or password mechanisms and periodically update their authentication
information is difficult at best. This paper describes a general-purpose
mechanism for authenticating
