Strongly Secure and Efficient Data Shuffle On Hardware Enclaves
Mitigating memory-access attacks on the Intel SGX architecture is an
important and open research problem. A natural notion of the mitigation is
cache-miss obliviousness which requires the cache-misses emitted during an
enclave execution are oblivious to sensitive data. This work realizes the
cache-miss obliviousness for the computation of data shuffling. The proposed
approach is to software-engineer the oblivious algorithm of Melbourne shuffle
on the Intel SGX/TSX architecture, where the Transaction Synchronization
eXtension (TSX) is (ab)used to detect the occurrence of cache misses. In the
system building, we propose software techniques to prefetch memory data prior
to the TSX transaction to defend the physical bus-tapping attacks. Our
evaluation based on real implementation shows that our system achieves superior
performance and lower transaction abort rate than the related work in the
existing literature.Comment: Systex'1

Proceedings of the NSSDC Conference on Mass Storage Systems and Technologies for Space and Earth Science Applications
The proceedings of the National Space Science Data Center Conference on Mass Storage Systems and Technologies for Space and Earth Science Applications held July 23 through 25, 1991 at the NASA/Goddard Space Flight Center are presented. The program includes a keynote address, invited technical papers, and selected technical presentations to provide a broad forum for the discussion of a number of important issues in the field of mass storage systems. Topics include magnetic disk and tape technologies, optical disk and tape, software storage and file management systems, and experiences with the use of a large, distributed storage system. The technical presentations describe integrated mass storage systems that are expected to be available commercially. Also included is a series of presentations from Federal Government organizations and research institutions covering their mass storage requirements for the 1990's
