Development and Testing of a Real-Time LoRawan Sniffer Based on GNU-Radio

En este documento se muestran las vulnerabilidades presentes en una red de sensores inalámbricas implementada sobre una red de área amplia de largo alcance (LoRaWAN por sus siglas en inglés) LoRaWAN y se identifican los posibles ataques que se podrían realizar a la red usando sniffing y/o replay. Los ataques a la red se realizaron implementando un analizador de protocolos (Sniffer) para capturar los paquetes. El Sniffer se implementó utilizando el hardware RTL2832U y se visualizó en Wireshark, a través de GNU-Radio. Las pruebas mostraron que se pueden amenazar la disponibilidad y confidencialidad de los datos a través de ataques de replay con verificación en el LoRa server utilizando hardware HackRF One y GNU-Radio. Aunque la especificación LoRaWAN tiene contadores para evitar ataques de replay, bajo condiciones adecuadas se lograría vulnerar la red llegando a realizar la denegación del servicio del nodo en el servidor.This paper shows the vulnerabilities present in a wireless sensor network implemented over a long-range wide area network (LoRaWAN) LoRaWAN, and identifies possible attacks that could be made to the network using sniffing and/or replay. Attacks on the network were performed by implementing a protocol analyzer (Sniffer) to capture packets. The Sniffer was implemented using the RTL2832U hardware and visualized in Wireshark, through GNU-Radio. Tests showed that data availability and confidentiality could be threatened through replay attacks with LoRa server verification using HackRF One and GNU-Radio hardware. Although the LoRaWAN specification has, frame counters to avoid replay attacks, under given the right conditions, this measure could be violated even deny service to the node on the server

CIBERER : Spanish national network for research on rare diseases: A highly productive collaborative initiative

Altres ajuts: Instituto de Salud Carlos III (ISCIII); Ministerio de Ciencia e Innovación.CIBER (Center for Biomedical Network Research; Centro de Investigación Biomédica En Red) is a public national consortium created in 2006 under the umbrella of the Spanish National Institute of Health Carlos III (ISCIII). This innovative research structure comprises 11 different specific areas dedicated to the main public health priorities in the National Health System. CIBERER, the thematic area of CIBER focused on rare diseases (RDs) currently consists of 75 research groups belonging to universities, research centers, and hospitals of the entire country. CIBERER's mission is to be a center prioritizing and favoring collaboration and cooperation between biomedical and clinical research groups, with special emphasis on the aspects of genetic, molecular, biochemical, and cellular research of RDs. This research is the basis for providing new tools for the diagnosis and therapy of low-prevalence diseases, in line with the International Rare Diseases Research Consortium (IRDiRC) objectives, thus favoring translational research between the scientific environment of the laboratory and the clinical setting of health centers. In this article, we intend to review CIBERER's 15-year journey and summarize the main results obtained in terms of internationalization, scientific production, contributions toward the discovery of new therapies and novel genes associated to diseases, cooperation with patients' associations and many other topics related to RD research

Measurement of the triple-differential dijet cross section in proton-proton collisions at √s =8TeV and constraints on parton distribution functions

A measurement is presented of the triple-differential dijet cross section at a centre-of-mass energy of 8TeV TeV using 19.7fb -1 of data collected with the CMS detector in proton-proton collisions at the LHC. The cross section is measured as a function of the average transverse momentum, half the rapidity separation, and the boost of the two leading jets in the event. The cross section is corrected for detector effects and compared to calculations in perturbative quantum chromodynamics at next-to-leading order accuracy, complemented with electroweak and nonperturbative corrections. New constraints on parton distribution functions are obtained and the inferred value of the strong coupling constant is α S (M Z )=0.1199±0.0015(exp) +0.0031 −0.0020 (theo), where M Z is the mass of the Z boson

Bose-Einstein correlations in pp, pPb, and PbPb collisions at root s(NN)=0.9-7 TeV

Quantum-statistical (Bose-Einstein) two-particle correlations are measured in pp collisions at root s = 0.9, 2.76, and 7 TeV, as well as in pPb and peripheral PbPb collisions at nucleon-nucleon center-of-mass energies of 5.02 and 2.76 TeV, respectively, using the CMS detector at the Large Hadron Collider. Separate analyses are performed for same-sign unidentified charged particles as well as for same-sign pions and kaons identified via their energy loss in the silicon tracker. The characteristics of the one-, two-, and three-dimensional correlation functions are studied as functions of the pair average transverse momentum (k(T)) and the charged-particle multiplicity in the event. For all systems, the extracted correlation radii steadily increase with the event multiplicity, and decrease with increasing k(T). The radii are in the range 1-5 fm, the largest values corresponding to very high multiplicity pPb interactions and to peripheral PbPb collisions with multiplicities similar to those seen in pPb data. It is also observed that the dependencies of the radii on multiplicity and k(T) largely factorize. At the same multiplicity, the radii are relatively independent of the colliding system and center-of-mass energy.Peer reviewe

Search for anomalous couplings in boosted WW/WZ →lvqq⁻⁻ production in proton–proton collisions at √s=8TeV

This Letter presents a search for new physics manifested as anomalous triple gauge boson couplings in WW and WZ diboson production in proton–proton collisions. The search is performed using events containing a W boson that decays leptonically and a W or Z boson whose decay products are merged into a single reconstructed jet. The data, collected at √s = 8 TeV with the CMS detector at the LHC, correspond to an integrated luminosity of 19 $fb$$^{-1}$. No evidence for anomalous triple gauge couplings is found and the following 95% confidence level limits are set on their values: λ ([-0.011,0.011]), Δ$κ$$_{Y}$ ([-0.044,0.063]) and Δg$\substack{Z\\I}$([-0.0087,0.024]). These limits are also translated into their effective field theory equivalents: c$_{www}$/Δ² ([-2.7, 2.7] TeV$^{-2}$, c$_{B}$/Δ² ([-14,17] TeV$^{-2}$, and $c$$_{W}$/Δ² ([-2.0,5.7] TeV$^{-2}$)
