Post-doctoral fellow Stochastic processes-based models for distributed ledgers: towards increased security and better performance - 24 month contract

Job description

IMT Atlantique

1. Context

Présentation of IMT Atlantique :

IMT Atlantique, internationally recognized for the quality of its research, is a leading general engineering school under the authority of the Ministry of Industry and Digital Technologies, ranked in the 3 main international rankings (THE, SHANGAI, QS). With three campuses in Brest, Nantes and Rennes, IMT Atlantique aims to combine digital technology and energy to transform society and industry through training, research and innovation.

Job environment :

The Maths&Net research team works on designing, describing, managing, securing and controlling various aspects of operators' communication networks. In a layered model, we are at the network layer (IP) level and above. Among the tools and methods used, we rely on stochastic models and algorithms to capture the high variability of such networks, as well as on game theory models that are particularly well suited to modeling distributed systems involving different interacting actors.

One of our main research axes nowadays is the analysis of distributed systems, aiming to improve their performance and security.

2. Objective

Propose access control solutions for DAG-based distributed ledgers. In particular, we are interested in stochastic processes based models and distributed algorithms for convex optimization, allowing to increase the security and the performance of such registres.
