5th CACR Information Security Workshop
Sharon Hagi, 724 Solutions Inc.
Wireless Security and the Evolution Towards PKI
In the early 90s, the emergence of personal mobile computing devices
signaled the beginning of the wireless networking age. Today, the
proliferation of Personal Digital Assistants (PDAs), Digital Cellular
Phones, 2-Way Pagers, Internet appliances and such, are providing easy
and practical Internet access to customers, anytime, anywhere.
Enterprises are now facing new challenges in deploying secure and robust
information services that are accessible from a wide range of wireless and
mobile computing devices. Wireless security and PKI introduce yet another
dimension to the complexity already inherited by the diversity and variety
of different device characteristics, computing power, operating systems,
bandwidth limitations, communication protocols and deployment models.
This presentation will attempt to explore some the many challenges in
building comprehensive and secure wireless information systems and give
compelling reasons for an evolution towards wireless PKI. Practical
examples will be drawn from 724's experience in this field as one of
the pioneering companies in providing wireless financial and e-commerce
