If you mean the paper linked as "slightly older research" (http://rump2009.cr.yp.to/8d9cebc9ad358331fcde611bf45f735d.pd...), it's slides from a talk entitled "Cross-VM Vulnerabilities in Cloud Computing" by Thomas Ristenpart, Eran Tromer, Stefan Savage, and Hovav Shacham, presented at Crypto'09's "rump session" (a session for short, amusing and/or late-breaking talks). Downloads slowly for me too, but eventually finishes (6mb pdf).

The following paper by the same authors, from a few months later, appears to be the published-paper version of that research, though, which is probably more useful: http://pages.cs.wisc.edu/~rist/papers/cloudsec.html
