Executive Summary

The authors present a new approach to verifying that a completely untrusted, Platform-as-a-Service cloud is correctly executing an outsourced web application. Web applications such as blogs, wikis, and online social networks are increasingly hosted on third-party, "Platform-as-a-Service" (PaaS) clouds. The owner outsources the execution of his application to a cloud provider - for example, Microsoft's Azure or Google's App Engine - and is periodically billed for the application's consumption of CPU time and network bandwidth.
