Abstract

The Maru project between Imperial College, Cambridge, and the Turing Institute, has just completed the task of getting Spark to run using Intel's SGX - this was a couple of years work, and involved a lot of systems partitioning to get map/reduce type tasks to run in the secure enclave's very limited memory. Along the way parallel work on getting the linux kernel library and secure communications and storage to fly was required. Some of this may have been partially undermined by the revelations about vulnerabilities in Intel CPU's microarchitecture due to speculation exposing ephemeral state outside of the enclave (and other related problems). I'll briefly talk about other work to help mitigate this using finer grain access control within the enclave, and on other CPUs.
