Descriptif

Security of Network and Applications

The objective of this class is to introduce security principles, on the theoretical, organizational and technical aspects. The points which are more specifically developed are: detection errors, firewall technics, network architecture, cryptology and VPN, anti-virus strategy. Are also discussed how to implement a security strategy, and some elements for the definition of a security policy. Some elements about safe networks, or networks for safety or critical applications, are also studied.

Distributed Algorithms and Network Systems

Objectives Distributed algorithms aim at obtaining a global goal by exploiting a large number of simple devices (``agents''), and their local interactions. These algorithms can be for the purposes of estimation in a wireless sensor network, or control e.g. of a self-organized robotic fleet. This introductory class will first review the necessary tools from graph theory and Markov chains, and then present consensus: a prototypical example of distributed algorithm, as well as a building block for more complex algorithms. Theory will be accompanied by implementation on a real-world sensor network: FIT/IoT LAB.Class schedule 

  1. Introduction: network systems 
  2. Graphs: fundamentals of algebraic graph theory
  3. Markov chains: convergence to invariant measure, Perron-Frobenius theorem 
  4. Consensus (time-invariant graph) 
  5. Consensus (gossip: randomly varying graph) 
  6. Consensus-based algorithms: using consensus as a building block of other algorithms (e.g., localisation from relative measurements, least-squares regression, gradient descent minimization, distributed Kalman filter, counting nodes in an anonymous network) 
  7. Labs (3): implementation of distributed algorithms on real sensor network, remotely using FIT/IoT LAB. Programming language: C.

Programmable Sockets

This two-sessions lab aims at establishing a communication with a PLC-like computer controlling a levitating ball. The work is related to the IP (TCP and UDP) libraries on Python, and to some more high-level protocols or technologies (HTTP, GRPCio for security constraints, etc.).
