uberSpark is an innovative system architecture and programming framework for modular provable security on commodity system software stacks. uberSpark faciliates compositional verification of security properties while supporting low-level programming languages such as C and Assembly. The salient features of uberSpark include:

  1. provide a verifiable object abstraction (called universal object abstractions or uberObject or uobject for short) to endow low-level system software with abstractions found in higher-level languages (e.g., objects, interfaces, function-call semantics, serialization, access-control etc.)
  2. facilitate easy refactoring of existing commodity (low-level) system software stacks into a collection of modular and composable uberObjects (üobject)
  3. enforce üobject abstractions using a combination of commodity hardware mechanisms, light-weight static analysis and formal verification.

The primary sub-projects of uberSpark are:

uberSpark core libraries and hardware model
The low-level verified runtime and hardware interface libraries along with a hardware model to interface to platform hardware during verification of a uobject
über eXtensible Micro-Hypervisor Framework (uberXMHF)
A commodity micro-hypervisor framework architected and verified using uberSpark, promoting the development of a new class of (verified) micro-hypervisor based applications ("uberApps") which provide security sensitive functionality in the context of existing commodity OS and regular applications
