Title - Ascend: Architecture for Secure Computation on Encrypted Data
Presented by - Srini Devadas – MIT
Friday, October 19
Abstract: We consider encrypted computation where the user specifies encrypted inputs to an untrusted program, and the server computes on those encrypted inputs. This can be achieved using Fully Homomorphic Encryption (FHE) without trusting anything on the server side, but FHE currently entails huge overheads. We describe a secure processor architecture, called Ascend, that guarantees privacy of data when arbitrary programs use the data running in a cloud-like environment (e.g., an untrusted server running an untrusted software stack). The trusted computing base is simply the processor chip and does not include any software.
The key idea to guarantee privacy is obfuscated instruction execution; Ascend does not disclose what instruction is being run at any given time, be it an arithmetic instruction or a memory instruction. Periodic accesses to external instruction and data memory are performed through an Oblivious RAM (ORAM) interface to prevent leakage through memory access patterns. An evaluation of processor architecture on SPEC benchmarks running on encrypted data is presented and overheads of encrypted computation are quantified.
Biography: Srini Devadas is the Edwin Sibley Webster Professor of Electrical Engineering and Computer Science at the Massachusetts Institute of Technology (MIT), where he has been on the faculty since 1988. He served as the Associate Head of EECS with responsibility for Computer Science from 2005-2011. Devadas has worked in the areas of Computer-Aided Design, testing, formal verification, compilers for embedded processors, computer architecture, computer security, and computational biology and has co-authored numerous papers in these areas and received 13 best paper awards. Devadas was elected a Fellow of the IEEE in 1998.
