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 services.
