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…

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…

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…

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…

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…

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…
