A Secure and Scalable Wide-Area Upload Service

摘要

In a recent paper, we introduced a framework termed Bistro to facilitate the building of scalable wide-area upload applications. An example of an important upload application is the submission of personal and business income tax forms over the Internet. Our intent for deploying the Bistro platform is not to rely on adding resources (such as hosts) to the Internet. Rather, we envision that people will want to install Bistro services on their hosts on the Internet and contribute their resources to the overall Bistro infrastructure because it will improve their performance as well. Since anyone will be allowed to install a Bistro server, security becomes a great concern since sensitive information such as income tax forms will be uploaded through the Bistro system. In this paper, we describe the basic framework and present a security protocol for the Bistro system as well as discuss its security properties.
