5th CACR Information Security Workshop

Converging Technologies: Internet Appliances and Wireless PKI
The new frontier for accessing Internet-based content and services is
via mobile, wireless devices such as digital cell-phones and palmtop
computers. The Wireless Application Protocol (WAP) provides a suite of
communications and security protocols meant to allow constrained wireless
devices to gain access to the same types of services as are currently
available through desktop browsers.
This presentation begins with an overview of WAP, with a focus on the
protocols and mechanisms which enable secure transactions to be performed
from the wireless device through to the desired Internet sites.
This is followed by an exploration of Wireless Public Key Infrastructure
(WPKI) initiatives, and how existing PKI technologies are being extended
and adapted to meet the enrollment, personalization and useage needs
specific to the unique and constrained environment of Internet Appliances.
Special attention is given to wireless e-commerce applications such as
banking, brokerage services, and shopping.
Ron Vandergeest leads the team responsible for the development of security
products and services for Internet Appliances, such as WAP (Wireless
Application Protocol) phones, palm-top computers and smart-pagers.
Mr. Vandergeest joined the Entrust team after nine years with
Bell Northern Reseach and Nortel. During this period, he held
a number of engineering positions, ranging from ASIC
(Application Specific Integrated Circuit) design, to leadership
of a team responsible for high-speed disaster recovery of
Nortel's CCS7 (Common Channel Signalling #7) products.
Mr. Vandergeest received a Bachelor of Engineering degree from
Carleton University, in 1985.
