WebALPS

Abstract

Web-based commerce is rife with scenarios where a party needs to trust properties of computation and data storage occurring at a remote machine, operated by a different party with different interests. In our WebALPS project, we have used off-the-shelf hardware and open source software to build trusted co-servers co-resident with Web servers, and bring the secure SSL channel all the way into these trusted co-servers. In this paper, we survey how this tool can be used to systematically address privacy and security issues in e-commerce.
