New paper Fighting Crimeware: An Architecture for Split-Trust Web Applications available. This Intel Research technical report presents a split-trust browsing architecture that splits web applications across a trusted personal device and an untrusted PC. Working with Richard Sharp, Roy Want, and others at Intel, we developed a system where sensitive information entered on a phone's keypad cannot be read by PC-based keyloggers, and data displayed on the phone's screen is hidden from screengrabbing malware. We implemented a prototype using a commercial cell phone and showed it could defend against a range of crimeware attacks including active injection and browser compromises.
