Summary:The post-PC revolution is bringing information access to a
wide-range of devices beyond the desktop, such as public kiosks, and
mobile devices like cellular telephones, PDAs, and voice based vehicle
telematics. However existing deployed Internet services are geared
toward the secure rich interface of private desktop computers. We
propose the use of an infrastructure-based secure proxy architecture to
bridge the gap between the capabilities of post-PC devices and the
requirements of Internet services. By combining generic content and
security transformation functions with service-specific rules, the
architecture decouples device capabilities from service requirements and
simplifies the addition of new devices and services. Security and
protocol specifics are abstracted into reusable components.
Additionally, the architecture offers the novel ability to deal with
untrusted public Internet access points by providing fine-grain control
over the content and functionality exposed to the end device, as well as
support for using trusted and untrusted devices in tandem. Adding
support for a deployed Internet service requires a few hundred lines of
scraping scripts. Similarly, adding support for a new device requires a
few hundred lines of stylesheets for the device format. The average
latency added by proxy transformations is around three seconds in our
unoptimized Java implementation
