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.

  • This postdoc position will be funded by the Rakes and AllOpticall2 ANR Projects. These projects involve Inria Taran (Rennes/Lannion), INL (Lyon), Lab-STICC (Lorient), and TIMA (Grenoble).

  • The Taran team has already a strong background in on-chip interconnects, and on the emerging interconnect paradigms (WiNoC, ONoC) targeted in this project.

  • Assignment


    Since few years we are witnessing the emergence of manycore architectures, namely to the implementation of massive parallelism on a single chip. Associated with the shrinking size of the transistors, these manycore architectures should reach the integration of thousands of heterogeneous cores allowing huge parallel computation capabilities suitable for high-performance embedded computing systems and HPC.

    To satisfy the increase of on-chip communication requirements of theses architectures 1, technology evolution has allowed for the integration of silicon photonics and wireless communications on chip, thus leading to Wireless Network-on-Chip (WiNoC) 2-3 and Optical Network-on-Chip (ONoC) 4-5 paradigms.

    As technology advances and the use of emerging on-chip interconnects increases, the need for secure design and implementation becomes increasingly criticial 6. Indeed, as on-chip interconnects are used to transfer data and instructions between different components within a system-on-a-chip (SoC), these interconnects are vulnerable to a variety of attacks, such as side-channel attacks and fault injection attacks, which can compromise the security of the entire system. As a result, securing on-chip interconnects is becoming an important design concern for developers and manufacturers of SoCs. This includes implementing security measures such as encryption, and fault tolerance to protect against potential threats and maintain the integrity of the system.

    The scope of the PostDoc position is relatively open and applicants are expected to identify the direction that suits them the most as a function of their background and interest. The goal is to improve the security of emerging on-chip interconnects in the context of manycore architectures.
