About the research centre or Inria department

The Inria Rennes - Bretagne Atlantique Centre is one of Inria's eight centres and has more than thirty research teams. The Inria Center is a major and recognized player in the field of digital sciences. It is at the heart of a rich R&D and innovation ecosystem: highly innovative PMEs, large industrial groups, competitiveness clusters, research and higher education players, laboratories of excellence, technological research institute, etc.


Project RIOT-fp https://future-proof-iot.github.io/RIOT-fp is an Inria Challenge with the objective of developing future-proof operating system libraries for application to IoT: RIOT.  Our PhD project is interested in one of the futures of RIOT: RIOT-rs, implemented in Rust. This computing base provides access to a vast ecosystem of analysis, code generation, verification and proof tools. It offers us to rethink a system software validation process that would suit both system programming and verification requirements (as one may expect from using, e.g., a theorem prover).


The notion of contract is one ideal such interface between the development and verification of system programs in Rust.  A contract allows, on one hand, to formally document the hypothesis and guarantees of system modules, functions, artifacts, with respect to global safety ad security requirements.  Contracts can be sufficiantly abstract and comprehensible for system programmers, and adequatly refined to meet the strongest requirements of mechanised verification.

Main activities

Our project will focus on the development of such a modular validation flow by case-studying the core of RIOT's implementation in Rust [riot-rs-core].  We define and exercise this workflow to characterize and validate global requirements ranging from race-condition, deadlock avoidance, priority management and schedulability, and/or memory isolation, faul isolation, information flow control.
