PHANTOM: practical oblivious computation in a secure processor
Martin Maas,Eric Love,Emil Stefanov,Mohit Tiwari,Elaine Shi,Krste Asanovic,John Kubiatowicz,Dawn Song +7 more
TL;DR: PHANTOM is the first demonstration of a practical, oblivious processor that can provide strong confidentiality guarantees when offloading computation to the cloud and is efficient in both area and performance.
Proceedings Article
Raccoon: closing digital side-channels through obfuscated execution
TL;DR: This paper presents a method of defending against a broad class of side-channel attacks, which it is argued about the correctness and security of the compiler transformations and demonstrates that the transformations are safe in the context of a modern processor.
Proceedings ArticleDOI
Complete information flow tracking from the gates up
Mohit Tiwari,Hassan M. G. Wassel,Bita Mazloom,Shashidhar Mysore,Frederic T. Chong,Timothy Sherwood +5 more
TL;DR: This work presents a novel architecture capable of tracking all information flow within the machine, including all explicit data transfers and all implicit flows (those subtly devious flows caused by not performing conditional operations).
Proceedings ArticleDOI
GhostRider: A Hardware-Software System for Memory Trace Oblivious Computation
TL;DR: This paper presents a new, co-designed compiler and architecture called GhostRider for supporting privacy preserving computation in the cloud, and formalized the approach and proved it enjoys MTO.
Proceedings ArticleDOI
Crafting a usable microkernel, processor, and I/O system with strict and provable information flow security
Mohit Tiwari,Jason Oberg,Xun Li,Jonathan Valamehr,Timothy E. Levin,Ben Hardekopf,Ryan Kastner,Frederic T. Chong,Timothy Sherwood +8 more
TL;DR: The approach is to construct a minimal but configurable architectural skeleton that couples a critical slice of the low level hardware implementation with a microkernel in a way that allows information flow properties of the entire construction to be statically verified all the way down to its gate-level implementation.
