Seminars of the Master 2 IFI (CSSR & UbiNet)

Seminars are fully part of the CSSR & UbiNet Curriculi of the Master 2 IFI, all students registered in these curriculi are requested to attend. (except for the UbiNet students when the seminar are given in French.)

The practical details of the evaluation of the Seminar activity will be detailed later, on this page. In any case, students attending the seminar are expected to take notes and be able to later discuss the topics presented during each seminar (possibly during an oral presentation and/or a written exam).

Students are also invited to investigate further the subjects presented during seminars on their own.


Seminar are organized on Thursdays. Check this page regularly for new updates.

  • 08/10 (11h00 - INRIA Kahn) - Colloquium Morgenstern - Xavier Leroy Comment faire confiance un compilateur? (possibly in French)
  • 15/10 - No seminar.
  • 22/10 - No seminar.
  • 29/10 (14h00 - Laboratoire I3S, Salle de Confrences) - Dino Lopez : Improving the performance of long life flows with Explicit Rate Notification protocols in heterogeneous large BDP networks.
    Seminaire reporte au Jeudi 17 Decembre
    In networks with best-effort trafic, congestion control mechanisms provide fair share of the network resources and congestion avoidance.Such congestion control mechanisms can be divided in 3 main groups:
    1. End-to-End (E2E) protocols, which only need the participation of the end-hosts,
    2. Active Queue Management (AQM) protocols, which implement congestion detection mechanisms in the routers.
    3. Explicit Rate Notification protocols, which need the participation of every node in the network. This group of protocols use the assistance from the forwarding devices to inform the senders about the best sending rate.
    In this seminar, first we will see why E2E protocols (e.g. TCP New Reno) are preferred over AQM and ERN protocols, even though E2E protocols perform poorly in large Bandwidth-Delay Product (BDP) networks. Then, we will see the strength and weakness of AQM protocols, and why ERN protocols cannot be used in current heterogeneous networks, even though they seem to overcome the problems of both E2E and AQM protocols. Finally, I will present solutions to enable the inter-operability between ERN protocols and heterogeneous large BDP networks.
  • 05/11 (14h00 - Laboratoire I3S, Salle de Confrences) Ludovic M : Intrusion Detection
    Seminar given in French.
    Ce sminaire constitue une introduction rapide au domaine de la dtection des intrusions. Nous prsentons tout d’abord le rle et le positionnement de ce service de scurit dans le paysage global de la scurit informatique. Nous expliquons ensuite les raisons pour lesquelles nous considrons que les approches actuelles, parfois relativement efficaces mais toujours trs empiriques, constituent un verrou technologique que des travaux de recherche doivent essayer de faire sauter. Finalement, nous avanons l’ide que pour parvenir faire sauter ce verrou il peut tre intressant de revenir des approches de dtection dfinies plus formellement, sans toutefois perdre de vue les aspects technologiques, souvent pointues, inhrents au domaine. Pour finir, nous illustrons cette ide en exposant une approche, propose Suplec, de dtection paramtre par la politique de scurit.
  • 12/11 (14h00 - ATTN: EPU, Salle 310) Juan-Carlos Maureira: A High-speed Handover for Mobile Wireless Networks.
  • 19/11 (11h00 - INRIA Kahn) Colloquium Morgenstern - Chris Cannings : Modeling evolutionary games
  • 03/12 (14h00 - Laboratoire I3S, Salle de Confrences) Refik Molva (Eurecom) : Safebook - a decentralized on-line social network for privacy
    This talk is about the distributed on-line social networking system called Safebook. Safebook tackles the security and privacy problems of online social networks by putting a special emphasis on the privacy of users with respect to the application provider. In order to assure privacy in the face of potential violations by the provider, Safebook is designed in a decentralized architecture relying on the cooperation among the independent parties that represent the users of the online social network. Safebook addresses the problem of building secure and privacy-preserving data storage and communication mechanisms in a peer-to-peer system by leveraging trust relationships akin to social networks in real life. The talk includes some details of Safebook architecture and a discussion of its security and privacy properties. The protocols of Safebook are evaluated in various attack scenarios with respect to privacy, integrity and availability.
  • 10/12 (11h00 - INRIA Kahn) Colloquium Morgenstern - James Pawley : Super-resolution Fluorescent Light Microscopy Techniques compared
  • 17/12 : Seminaire Dino Lopez (voir plus bas).
  • 14/01 (14h00 - Location TBD) Lucille Sassatelli : Topic TBD.
    Seminaire reporte
  • 21/01 (14h00 - Location TBD) Stphane Bortzmeyer : DNSSec
  • 28/01 (14h00 - Location TBD) Giovanni Stea, Universit Di Pisa : Packet scheduling for Quality of Service
    The talk will introduce the problem of packet scheduling at network interfaces. It will explain why packet scheduling algorithms for tasks on a processor are generally not a viable choice. It will then describe the weighted fair queuing paradigm, and show several ways to approximate it, at different accuracy/complexity trade-offs. It will then show how to derive performance guarantees at both a single scheduling hop and in an end-to-end perspective.
  • 11/02 (11h00 - INRIA Kahn) Colloquium Morgenstern - Brigitte Valle : Thorie de l’information : modles, algorithmes, analyse
  • 18/02 Pas de sminaire (Vacances UFR Sciences)
  • 25/02 (14h00 - Location TBD) Florent Masseglia : Data mining for security.
