  , 2017. The rising wave of attacks on communicating embedded systems has exposed their users to risks of information theft, monetary damage, and personal injury. Unprotected remote access to connected features on conventional vehicles already can provide attackers operational control. With the impending introduction of autonomous vehicles, their increased connectivity of autonomous vehicles will offer even more avenues for attack. In this paper, we present a survey of previous attacks on connected vehicles, and the prospective security risks threatening autonomous vehicles. To address these vulnerabilities, previous projects on connected vehicle security, such as EVITA, proposed countermeasures including key distribution and Hardware Security Modules. The expense and overhead of these solutions can be high, leading us to place them only where necessary. We propose developing systems using our toolkit TTool, which locates insecure communications, and then determines performance impact of these countermeasures through modelling and formal verification.

  , 2017, 57, pp.1-13. The time-predictable design of computer architectures for the use in (hard) real-time systems is becoming more and more important, due to the increasing complexity of modern computer architectures. The design of predictable processor pipelines recently received considerable attention. The goal here is to find a trade-off between predictability and computing power. Branches and jumps are particularly problematic for high-performance processors. For one, branches are executed late in the pipeline. This either leads to high branch penalties (flushing) or complex software/hardware techniques (branch predictors). Another side-effect of branches is that they make it difficult to exploit instruction-level parallelism due to control dependencies. Predicated computer architectures allow to attach a predicate to the instructions in a program. An instruction is then only executed when the predicate evaluates to true and otherwise behaves like a simple nop instruction. Predicates can thus be used to convert control dependencies into data dependencies, which helps to address both of the aforementioned problems. A downside of predicated instructions is the precise worst-case execution time (WCET) analysis of programs making use of them. Predicated memory accesses, for instance, may or may not have an impact on the processor's cache and thus need to be considered by the cache analysis. Predication potentially has an impact on all analysis phases of a WCET analysis tool. We thus explore a preprocessing step that explicitly unfolds the control-flow graph, which allows us to apply standard analyses that are themselves not aware of predication.

• Représentations continues dérivées des caractères pour un modèle de langue neuronal à vocabulaire ouvert

  , 2017. Cet article propose une architecture neuronale pour un modèle de langue à vocabulaire ouvert. Les représentations continues des mots sont calculées à la volée à partir des caractères les composant, gràce à une couche convolutionnelle suivie d'une couche de regroupement (pooling). Cela permet au modèle de représenter n'importe quel mot, qu'il fasse partie du contexte ou soit évalué pour la prédiction. La fonction objectif est dérivée de l'estimation contrastive bruitée (Noise Contrastive Estimation, ou NCE), calculable dans notre cas sans vocabulaire. Nous évaluons la capacité de notre modèle à construire des représentations continues de mots inconnus sur la tâche de traduction automatique IWSLT-2016, de l'Anglais vers le Tchèque, en ré-évaluant les N meilleures hypothèses (N-best reranking). Les résultats expérimentaux permettent des gains jusqu'à 0,7 point BLEU. Ils montrent aussi la difficulté d'utiliser des représentations dérivées des caractères pour la prédiction.

  International Journal of Antennas and Propagation, 2017, pp.1-15. This paper deals with a new methodology to assess the exposure induced by both uplink and downlink of a cellular network using 3D electromagnetic simulations. It aims to analyze together the exposure induced by a personal device (uplink exposure) and that induced by a base station (downlink exposure). The study involved the major parameters contributing to variability and uncertainty in exposure assessment, such as the user’s posture, the type of wireless device and the propagation environment. Our approach is relying basically on the modeling of the power radiated by the personal device and the ambient electric field, while taking into account the effects of human body shadowing and the propagation channel fluctuations. The exposure assessment as well as the human-wave interactions have been simulated using the finite difference in time domain method (FDTD). In uplink scenarios, four FDTD simulations were performed with a child model, used in two postures (sitting and standing) and in two usage scenarios (voice and data), which aimed to examine the exposure induced by a mobile phone and a tablet emitting, respectively, at 900 MHz and 1940 MHz. In the downlink scenario, a series of FDTD simulations of an exposure to a single plane wave and multi-plane waves have been conducted, and an efficient metamodeling of the exposure using the Polynomial Chaos approach has been developed.

• SC-PTM or MBSFN for Mission Critical Communications?

  , 2017, pp.1-6. Long Term Evolution (LTE), designed by 3rd Generation Partnership Project (3GPP) to increase the capacity of radio mobile communications, has been endorsed by multiple public protection and disaster relief organizations as a next generation technology for Professional Mobile Radio (PMR) networks, which convey business and mission critical communications. One of the main services of PMR is the group communication that can be seen as a Multimedia Broadcast Multicast Service (MBMS). LTE offers functionality to transmit this type of flows either by MBMS over Single Frequency Network (MBSFN), or Single-Cell Point-To-Multipoint (SC-PTM). In this paper, we compare MBSFN, SC-PTM and unicast transmissions in terms of radio quality, system spectral efficiency and cell coverage. Our main conclusion is that SC-PTM together with Transmission Time Interval (TTI) bundling transmissions offers a flexible solution to trade coverage off for capacity.

• Nonasymptotic convergence analysis for the unadjusted Langevin algorithm
  
  • Durmus Alain
  • Moulines Éric
  The Annals of Applied Probability, Institute of Mathematical Statistics (IMS), 2017, 27 (3), pp.1551 - 1587. In this paper, we study a method to sample from a target distribution π over Rd having a positive density with respect to the Lebesgue measure, known up to a normalisation factor. This method is based on the Euler discretization of the overdamped Langevin stochastic differential equation associated with π. For both constant and decreasing step sizes in the Euler discretization, we obtain nonasymptotic bounds for the convergence to the target distribution π in total variation distance. A particular attention is paid to the dependency on the dimension d, to demonstrate the applicability of this method in the high-dimensional setting. These bounds improve and extend the results of Dalalyan [J. R. Stat. Soc. Ser. B. Stat. Methodol. (2017) 79 651–676]. (10.1214/16-AAP1238)
