Post-doctoral positionDesign, characterization and modelling of a random number generator based on oscillating structures in FPGA and ASIC

Duration: 12 months renewable
Start: as soon as possible
Funding: PSPC-regions program funded by the Auvergne Rhône Alpes region

Project outline:
The PSPC-regions project "SECURE-RISC-V" includes 3 partners: two small French companies Tiempo and GreenWaves-Technologies, and the Hubert Curien laboratory in Saint-Etienne.
The objective of the project is to secure microcontrollers targeting IoT applications and based on a RISC-V architecture with an adapted hardware security element.
GreenWaves-Technologies provides a high-performance, low-power multi-core architecture that is secured by the TIEMPO's secure element certifiable CC EAL5+ IP (intellectual property). The Hubert Curien laboratory provides support for the design and stochastic modelling of the random number generator based on asynchronous rings - STR (for Self-timed rings), for the design and verification of stochastic tests dedicated to the generator, as well as for the verification of the generator's security and the efficiency of its dedicated tests.

- Study and modelling of asynchronous rings (STR) as a source of randomness in digital circuits.
- Implementation of random number generators (TRNG) based on these asynchronous rings in FPGA and ASIC circuits.
- Analysis of the statistical properties of the generated numbers.
- Stochastic modelling of the proposed generators.
- Proposal of embedded tests dedicated to the generators, based on their stochastic models.

Candidate profile:
- Ph.D. degree required
- Good knowledge of digital electronics and embedded systems
- CAD tools and FPGA design (Intel, Xilinx or Microsemi) as well as simulation tools (Modelsim)
- ASIC design using Cadence tools (design, simulation, verification)
