Dynamic Information Flow Tracking (DIFT) on Zynq SoC/Contrôle de flux d’information sur Zynq SoC.

1 June 2017 @ 15 h 30 min - 17 h 00 min
Room 153, CentraleSupélec
Cesson-Sévigné, 35510 France

Presenter: Muhammad Abdul Wahab Abstract: During the last decade, number of security vulnerabilites has grown steadily. Nowadays, many attacks exploit low level mechanisms. In the context of computer security, it is necessary to add a mechanism to avoid these software attacks. Dynamic Information Flow Tracking (DIFT) allows to protect against several software attacks (e.g. buffer overflow, crosssite scripting, injection SQL, data leakage, etc). After presenting DIFT, we will have a look at DIFT implementation on Zynq SoC. Especially, we will…

Cesson-Sévigné, 35510 France

Titre/title: Décomposition PAM d'un signal CPM avec encodage duo-binaire - Application à la modulation SOQPSK / PAM Decomposition of Ternary CPM With Duobinary Encoding – Application to SOQPSK modulation Résumé:: Dans ce séminaire, on détaille une nouvelle décomposition PAM (Pulse Amplitude Modulation) d'un signal CPM à symboles duo-binaire. Appliquée à la modulation SOQPSK - modulation très utilisée dans le domaine de la télémesure aéronautique- cette décomposition fait apparaître un pulse principal unique prépondérant contrairement à la décomposition de référence à…

Clustering Nature of BS Deployment and Traffic Demand in Cellular Networks

13 September 2017 @ 15 h 30 min - 17 h 00 min

Presenter: Yifan Zhou Abstract: This work is based on large-scale real data from on-operating cellular networks. Traditionally, the architecture and service paradigm of cellular networks are based on the homogeneous assumptions of base stations (BSs) deployment and user requests pattern, such as hexagonal grid and Poisson arrivals. However, due to the evolutionary progresses, cellular networks become more and more complicated in these decades. In this seminar, we will firstly review the state-of-art real data analysis of cellular traffic consumption on…

Multi-Armed Bandit Learning in IoT Networks: Learning helps even in non-stationary settings

23 November 2017 @ 15 h 30 min - 17 h 00 min
Room 153, CentraleSupélec
Cesson-Sévigné, 35510 France

Presenter: Lilian Besson Abstract: Setting up the future Internet of Things (IoT) networks will require to support more and more communicating devices. We prove that intelligent devices in unlicensed bands can use Multi-Armed Bandit (MAB) learning algorithms to improve resource exploitation. We evaluate the performance of two classical MAB learning algorithms, UCB1 and Thompson Sampling, to handle the decentralized decision-making of Spectrum Access, applied to IoT networks; as well as learning performance with a growing number of intelligent end-devices. We…

Transmission d’Information Stratégique/ Strategic Transmission of Information

21 December 2017 @ 15 h 30 min - 17 h 00 min
Room 153, CentraleSupélec
Cesson-Sévigné, 35510 France

Abstract: What information one has to transmit when the receiver has a different objective from the sender ? Originally in the Economics literature, the problem of ``Strategic Information Transmission'' arises in decentralized networks when the users are considered as players, that choose autonomously a transmission scheme in order to maximize their own utility function. The key difference with conventional communication paradigm is that the meaning of the information symbol has to be considered carefully. Indeed, each information might have a…

From Quantum Physics to Digital Communication: Single Side-Band Continuous Phase Modulation – Dr. Haïfa Fares , EC @ SCEE\IETR, CentraleSupélec-Rennes

19 April 2018 @ 15 h 30 min - 17 h 00 min
Room 153, CentraleSupélec
Cesson-Sévigné, 35510 France

Abstract: The transmission of digital data uses a carrier wave whose phase, frequency or amplitude is modulated to code the binary pattern carrying the digital information. All the modulations considered so far are characterized by  a symmetric spectrum around the carrier frequency (double side band (DSB) spectrum). As the upper and lower side band both carry the same information, strategies to filter one of the two side band to give a Single Side Band (SSB) spectrum have been designed for…

Exploiting of Pulse Width Modulated Electrical Network for Data Transmission using Power Line Communication – Nabil Zaraneh

26 April 2018 @ 15 h 30 min - 17 h 00 min
Room 153, CentraleSupélec

Résumé: Les applications de variation de vitesse des machines alternatives mettent en oeuvre des réseaux Modulés en Largeur d’Impulsion (MLI). La commande de ces machines nécessite la connaissance de données comme la vitesse ou la position du rotor. La transmission des données par Courant Porteur en Ligne (CPL) sur le réseau d’énergie permet de simplifier l’installation et l’entretien du système, d’augmenter sa fiabilité et de réduire son coût. Les modems CPL actuellement disponibles ne sont pas compatibles avec les applications de…

Hardware Accelerators for Dynamic Malware Detection Methods for Mobile – Muhammad Abdul WAHAB, PhD Student @SCEE\IETR, CentraleSupélec Campus de Rennes.

17 May 2018 @ 15 h 30 min - 17 h 00 min
Room 153, CentraleSupélec
Cesson-Sévigné, 35510 France

Abstract: The number of smart and connected mobile devices is increasing every year. In 2017, 20 billion connected devices were used and it is expected to rise up to 75 billion devices in 2025. With increased number and volume of smart devices, the interest of attackers to abuse them is rising, making their security one of the main challenges. The main mean that the attackers use in order to abuse mobile devices is malicious software, shortly called malware. The two…

Multi-Access Edge Computing (MEC): a key enabler of end-to-end latency improvement for 5G communications

4 July 2018 @ 16 h 00 min - 17 h 30 min
Room 153, CentraleSupélec
Cesson-Sévigné, 35510 France
+ Google Map

Abstract: The need for efficient use of network resources is continuously increasing with the grow of traffic demand, however, current mobile systems have been planned and deployed so far with the mere aim of enhancing radio coverage and capacity. Unfortunately, this approach is not sustainable anymore, as 5G communication systems will have to cope with huge amounts of traffic, heterogeneous in terms of space, time and Quality-of-Service (QoS) requirements. At the same time, the advent of Multi-access Edge Computing (MEC)…
