Objets connectés : les réseaux LoRaWAN, vulnérables aux attaques de hackers

Pour en savoir plus et paramétrer les cookies... Accueil GilbertKALLENBORN Journaliste Un chercheur en sécurité a décortiqué la technologie LoRaWAN, soutenue notamment par Orange et Bouygues Télécom. Promis à un bel avenir, l'Internet des objets de demain s'appuiera notamment sur des communications radio bas débit, permettant d'interconnecter une multitude de capteurs à une distance de plusieurs kilomètres tout en limitant au maximum la dépense énergétique. Cette analyse montre, une fois de plus, que l’on est encore loin d’un niveau de sécurité satisfaisant dans l’internet des objets, en tous les cas pour certains usages. Sur le papier, pourtant, l’histoire commençait bien. Tweeter. Car-to-Car Communication. Hariharan Krishnan hardly looks like a street racer.

Car-to-Car Communication

With thin-rimmed glasses and a neat mustache, he reminds me of a math teacher. And yet on a sunny day last September, he was speeding, seemingly recklessly, around the parking lot at General Motors’ research center in Warren, Michigan, in a Cadillac DTS. Car-to-Car Communication Breakthrough Cars that can talk to each other to avoid crashes. Why It Matters More than a ­million people are killed on roads worldwide every year. I was in the passenger seat as Krishnan wheeled around a corner and hit the gas. The technology that warned of the impending collision will start appearing in cars in just a couple of years. Already many cars have instruments that use radar or ultrasound to detect obstacles or vehicles. Car-to-car communication should also have a bigger impact than the advanced vehicle automation technologies that have been more widely heralded.

LP WAN Conference 2016. LPWA networks constitute an ideal solution for machine-to-machine (M2M) and the Internet of Things (IoT) applications that necessitate wide coverage and a sparing use of energy at a limited cost.

Smart City (with its sensors embedded in an urban setting), water, gas & electricity metering, e-health, connected buildings, agriculture… these are amongst the many applications that can be potentially covered by LPWA networks and that have a very bright future ahead of them. The experts are wagering on an explosion of the number of LPWA connections in the next 8 years. According to the analyst firm Machina Research, more than 3 billion LPWA-enabled M2M connections will be deployed between now and 2023, exceeding the number of M2M cellular (2G, 3G, 4G…) connections. What technical solutions are best positioned in the market? The agenda: technology comparisons, deployments, startups new ecosystem The scientific committee. LPWAN: Choice Overload and Confusion. The Low Power Wide Area Network (LPWAN) space is really heating up.

LPWAN: Choice Overload and Confusion

Just in the last few weeks we have seen some exciting announcements, such as the Mobile IoT Initiative from GSM Association (GSMA) , and a new LPWAN public network named the Machine Network from Ingenu (formerly On-Ramp). As exciting as these announcements are, I do not believe they are positive developments for the LPWAN sector. There are too many competing technologies leading to choice overload and confusion. There is clearly a gap in the industry today that needs to be filled by LPWAN technologies. The key characteristics defining LPWAN technology are as follows: Low cost: for devices, infrastructure and connectivity Low bandwidth and high latency: hundreds of bytes or less, every ten minutes or more Long battery life: ten years on a single AA battery Wide area coverage: reliable coverage with range measured in kilometers Strong propagation characteristics: able to penetrate underground and deep into buildings.

LPWAN. Low-Power Wide-Area Network (LPWAN) or Low-Power Network (LPN) is a type of wireless telecommunication network designed to allow long range communications at a low bit rate among things (connected objects), such as sensors operated on a battery.[1][2] Platforms and technologies[edit] References[edit] Further reading[edit] Lee, Chang-Jae, Ki-Seon Ryu, and Beum-Joon Kim.

Mais que cachent-ils derrière leur design épuré ? Des systèmes et logiciels embarqués qui les font fonctionner. Près de 76 000 entreprises sont impliquées dans les systèmes et logiciels embarqués en France selon l’étude 2014 de l’Opiiec (Observatoire paritaire des métiers de l’informatique, de l’ingénierie, des études et du conseil), conduite par le cabinet Kyu Associés. Après avoir fondé son développement sur les secteurs d’application de pointe (militaire, aérospatial, ferroviaire, nucléaire, automobile, médical...), cette filière cherche un nouveau souffle dans les objets connectés.
