PriSC 2020 Principles of Secure Compilation

Time Zone

The program is currently displayed in (GMT-06:00) Saskatchewan, Central America.

The GMT offsets shown reflect the offsets at the moment of the conference.

Time Band

By setting a time band, the program will dim events that are outside this time window. This is useful for (virtual) conferences with a continuous program (with repeated sessions).
The time band will also limit the events that are included in the personal iCalendar subscription service.

Abstract

Lightweight, safe, and fast execution of untrusted code is valuable in many contexts and can, in theory, be achieved via software fault isolation (SFI). Unfortunately, technological and marketplace hurdles have prevent mass adoption of previous SFI technologies. We propose to use WebAssembly to overcome these hurdles. Conceretely, we describe ongoing work on a formally verified sandboxing compiler, from WebAssembly to native code, towards this goal.
