Embedded Rust & Secure Software Updates for Low-Power Open Source Distributed System Software

Renewable contract : Yes

Level of qualifications required : Graduate degree or equivalent

Other valued qualifications : MSc

Fonction : Temporary scientific engineer

About the research centre or Inria department

The Inria Saclay-Île-de-France Research Centre was established in 2008. It has developed as part of the Saclay site in partnership with Paris-Saclay University and with the Institut Polytechnique de Paris .

The centre has 39 project teams , 27 of which operate jointly with Paris-Saclay University and the Institut Polytechnique de Paris; Its activities occupy over 600 people, scientists and research and innovation support staff, including 44 different nationalities.


In the context of the RIOT-rs project (as well as RIOT) and in partnership with Continental on secure IoT software updates, this position will focus on designing and leading the development of cybersercure open source buidling blocks for an embedded software platform : a Rust-based, general-purpose OS running on heterogeneous low-power 32-bit microcontrollers (Arm Cortex-M, RISC-V, ESP32...).

Low-power devices embarking such microcontrollers are typically connected to the network via various low-power wireless techniques (BLE, 802.15.4, LoRa...) and low-power IPv6 secure protocol stacks. Recently, new standards have been specified in this domain, including the protocols necessary for SUIT-compliance, the new state-of-the-art regarding IoT software update security. In parallel, the development and integration of various relevant or upcoming cryptographic libraries (in particular NIST contenders) has become necessary to prepare for next-generation, post-quantum attacks.

For further reading, see the output of RIOT-fp, a cybersecurity research project w.r.t. which the work envisionned here will be a follow-up.

Several positions are available! They will remain open until they are filled.


Collaboration :
The recruited person will be in connection with, RIOT-rs developers, the RIOT open source community, as well as Inria researchers in the domain of secure low-power IoT, cryptography and formal verification.

Responsibilities :
Depending on the profile, the recruited person will either be responsible for core embedded OS development, for the necessary protocols SUIT software update security, or for the integration of various relevant cryptographic libraries and primitives.

Steering/Management :
The person recruited will be in charge of steering the developer community snowballing around the open source code base.
