Cybersécurité dans l'espace : investissement du gouvernement du Canada dans la technologie quantique

Agence spatiale canadienne

LONGUEUIL, QC, le 14 juin 2019 /CNW Telbec/ - Pour protéger l'économie numérique du Canada, il faut empêcher les pirates informatiques d'avoir accès aux données. La cybersécurité est une priorité du gouvernement du Canada. La mission satellitaire canadienne QEYSSat (pour Quantum Encryption and Science Satellite) aura recours à la technologie quantique pour protéger les télécommunications dans l'espace.

L'Agence spatiale canadienne accorde un contrat de 30 millions de dollars à l'entreprise Honeywell pour la conception et toutes les étapes de la réalisation de la mission QEYSSat.

Les méthodes de chiffrement actuelles devraient être dépassées d'ici une dizaine d'années à cause de la puissance de traitement exceptionnelle des ordinateurs quantiques. QEYSSat, dont le lancement est prévu pour 2022, fera la démonstration de la technologie de distribution quantique de clés (DQC) par satellite. Cette technologie de chiffrement en émergence offrira au Canadaune méthode encore plus efficace de sécuriser la transmission d'informations.

Dans le cadre du contrat, l'entreprise Honeywell sera chargée des activités suivantes liées à QEYSSat : construction, tests, livraison, formation des opérateurs et mise en service. Le satellite servira de lien dans l'espace pour transmettre des clés de chiffrement entre les stations terrestres. Le travail de l'entreprise devrait se poursuivre jusqu'à la fin de 2022.

La mission QEYSSat est le point culminant d'une série d'activités de recherche et de développement technologique réalisées par l'Institut d'informatique quantique avec le soutien du gouvernement du Canada. Gr'ce à QEYSSat, le Canada sera de plus en plus près de disposer d'un service de télécommunications quantique opérationnel dans l'espace et d'une technologie de pointe pour l'aider à respecter ses priorités en matière de cybersécurité.

Les leçons tirées de la mission QEYSSat serviront au développement de futurs systèmes opérationnels pour le gouvernement qui assureront aux Canadiens un accès très sûr aux services. La sécurité renforcée autour des activités en ligne et des transactions financières de tous les jours, comme au guichet automatique bancaire, figure parmi les applications commerciales visées.

En plus de respecter le principe de la sécurité de la Charte canadienne du numérique, cette mission s'inscrit dans le Plan pour l'innovation et les compétences et la nouvelle Stratégie spatiale pour le Canada du gouvernement du Canada puisqu'elle permettra de sécuriser les futures télécommunications et de renforcer la sécurité et la souveraineté nationales.

« La mission QEYSSat constitue une autre étape du plan de notre gouvernement de veiller à ce qu'au Canada, les citoyens soient sûrs que leurs données et leurs renseignements personnels sont protégés. Le développement de ces nouvelles technologies offrira aussi un grand potentiel de transformation des marchés et permettra d'établir une économie solide qui profitera à tous. »

L'honorable Navdeep Bains, ministre de l'Innovation, des Sciences et du Développement économique

En bref

  • Les ordinateurs quantiques seront plusieurs millions de fois plus rapides que les ordinateurs actuels. Ils pourront donc déchiffrer rapidement les mots de passe, les numéros d'identification personnels et les autres mesures de protection actuelles, ce qui accroit la vulnérabilité des renseignements confidentiels et personnels.

  • La technologie actuelle de distribution quantique de clés (DQC) nécessite des c'bles à fibres optiques au sol, où une clé ne peut être distribuée plus loin que 200 kilomètres. QEYSSat vise à démontrer la DQC entre un satellite et un réseau de stations terrestres, ce qui permettrait de surmonter cette limite de distance.

  • En testant et en faisant la démonstration de la DQC dans l'espace, l'Agence spatiale canadienne veut fournir une plateforme spatiale gouvernementale aux intervenants fédéraux et au milieu scientifique canadien.

  • Le budget de 2017 prévoit 80,9 millions de dollars pour l'Agence spatiale canadienne afin de soutenir la réalisation de nouveaux projets et l'utilisation d'innovations canadiennes dans l'espace, comme la mission QEYSSat de chiffrement et de science quantiques. La mission appuiera les capacités émergentes du Canada dans le domaine de la distribution quantique de clés, qui pourrait assurer la sécurité des télécommunications à l'aide de codes de chiffrement impossibles à pirater.

  • La valeur du contrat (30 millions de dollars) ne comprend pas les taxes.

    RPAS community gathers for Tech Demo 2

    Once again this year, nearly 150 players in the aeronautics industry met at the Centre d'excellence sur les drones (CED) for the second edition of Tech Demo, where the remotely piloted aircraft systems (RPAS) community got together to share technological advances. During this event, which took place on Sept. 25 and 26 in Alma, Que., participants learned more about the latest developments from Transport Canada, the Royal Canadian Air Force and Royal Canadian Navy, and the National Research Council of Canada (NRC). They also attended various conferences exploring drone image recognition, multi-mission systems, the niche of excellence in civil and commercial UAVs, ways to reduce time to market through drone simulation and trends in the drone ecosystem. Guests also had the opportunity to discuss issues related to operations beyond visual line of sight (BVLOS), and take part in three panels about anti-UAV systems and airspace management. Seven system demonstrations were also carried out during the event, including one featuring a mastodon weighing more than 300 kilograms. “This autonomous system was developed for various surveillance and civil security missions by Quebec company Laflamme in collaboration with the American company General Dynamics. It was the first public technological demonstration of this system in Quebec, which generated a great deal of interest from the stakeholders present,” commented CED director general Marc Moffatt. He also added that, once again this year, the activity welcomed several major manufacturers, including Bell Helicopter, Bombardier, General Atomics, CAE, L3, Leonardo, and many others. According to CED president Alain Fortin, hosting an event like Tech Demo is very significant for the industry. “The drone community needs events around which to gather to feed each other. We are obviously thrilled with the scope of this second edition and, above all, very proud of the quality of the speakers in attendance. Several actors who orchestrate the development of drone regulation in Canada were among us over the past two days to listen to what the community had to teach them and to learn more about the potential of the CED,” said Fortin. “Our speakers come from all over the world, including the United States, England, Italy and even Ukraine. Over the years, the CED and its partners have built a whole regional ecosystem around the drone and we can see now that its strategic role in the development of this sector is recognized and well established,” he added. Made possible with the financial support from the Ministère de l'Économie et de l'Innovation as well as General Dynamics Missions Systems, Kongsberg Geospatial Ltd. and CAE, the event has become a major annual event that is eagerly awaited by the industry. https://www.skiesmag.com/press-releases/rpas-community-gathers-for-tech-demo-2

    ‘First-class’ fighter pilot becomes eVTOL entrepreneur

    BY NATASHA MCKENTY | JANUARY 28, 2021 Estimated reading time 14 minutes, 58 seconds. Brandon Robinson's Royal Canadian Air Force (RCAF) and Top Aces fighter pilot exploits compare to those of a protagonist in a blockbuster movie. After graduating from the Royal Military College of Canada with First Class Honours, his career quickly skyrocketed from frontline fighter squadron to being selected for the prestigious Fighter Weapons Instructor Course (FWIC) – the Canadian version of Top Gun. He obtained an MBA at Royal Roads University, and then did a tour in Ottawa where he “managed over $4 billion in procurement projects for the Fighter Force.” He spent the next few years instructing for FWIC. “Think ‘Viper' from the movie Top Gun,” he laughed. I then completed our Joint Command and Staff College program for those flagged for senior leadership.” While instructing for FWIC, Robinson earned the CF-18 fighter pilot instructor role at 410 Squadron in Cold Lake, Alberta, leading into oversight of CF-18 Fleet Tactical Standards, and then onto senior project management with a deputy director role in multiple Air Force projects. Robinson is modest. He credits his competitive nature “and a lot of luck” for his success. “I fully acknowledge that without exceptionally talented and competitive friends, I would not have passed, let alone have been fortunate enough to fly jets,” he told Skies. He found Military College to be physically and emotionally demanding, having a way of teaching you your limits and how to “be at peace with them.” Despite the challenges, he was one of the top five engineers in the program all four years. For Robinson, aviation was innate. His grandfather, RCAF Capt Eric Robinson was a Second World War bomber pilot. His father, Brian Robinson, began flying at the age of 14, but his hopes of joining the Air Force were grounded when he learned his vision wasn't good enough. “My father was very young when he and [my grandfather] built from scrap metal what is now a family airplane — an old RC-3 Republic Seabee aircraft.” Brian retired from his day job to turn the family hobby into a successful custom aviation engineering business. There was always “an army of airplanes” in and around Robinson's home. The first time Robinson piloted a plane, he was three years old. His grandfather let him sit in the seat in front of him. “I couldn't sit. I had to stand,” he laughed. “He said, ‘OK, you have control, so take us over there.'” That experience “made an imprint” for Robinson. After high school, much to his “mother's chagrin,” he joined the RCAF to “fly fast jets.” After military training, “there's a big [graduation] ceremony where they hand out the slots, and I remember looking at the card and seeing the CF-18 symbol on the bottom,” he said. Internally, he was bursting. Not surprisingly, when asked about the memorable moments of his career, he said it's difficult to choose. Robinson recalled, after being on the Squadron for just three months in Bagotville, Quebec, he was deployed to Hawaii for a joint exercise with the U.S. Navy. “The U.S. Navy has this big exercise, and the Canadians were asked to go,” he said. “So, we ferried CF-18s across the country, from Quebec to Comox, British Columbia. We overnighted, met up with an aerial refueler and then the next thing I know I'm in the middle of the Pacific Ocean, tanking off a refueler. There's a portion where, if you can't get gas, you're going to have to eject because you can't get back to land. I'm a 27-year-old kid who only has 200 hours of experience in this CF-18, and I'm over the middle of the ocean thinking, ‘OK, you better make this happen.' It's not the easiest maneuver either,” he laughed. Robinson shared the story of how he earned his call-sign: Repo. “I was flying, and my left engine essentially blew up; one of the main turbine hubs fractured. It severely crippled the aircraft, placing it into a reversionary control architecture. The engine was destroyed, and the aircraft was on fire,” he said. After 10 “very long seconds” of being “out of control,” he “dealt with the fire” and regained control. “I was able to land it safely back at the base. However, it was too badly damaged to fix. So, the joke was that the government had to repossess or repo it,” he laughed. “The damaged engine almost fell out when I landed.” He remembered flying low-level over the ocean while “shooting missiles at drones and dropping bombs on remote-controlled moving ships; being in front of 100 angry fighter pilots leading a NATO coalition strike mission; [and] early morning departures over Torrey Pines in California to dogfight over the ocean.” In 2018, with 20 years of service and a list of neck and spine injuries in his rear-view, he knew it was time to find adrenaline elsewhere. “You can't pull seven-and-a-half Gs for 20 years without hurting a few things,” he laughed. Leaving, he admitted, was a difficult decision, but entrepreneurship was also on his radar. The kid that grew up in rural Ontario, Canada, with an “army of airplanes” at his disposal and a military career most would envy, headed out to his next call of duty. He joined forces with his father to start Horizon Aircraft, an aerospace startup that is currently developing the Cavorite X5 — a new eVTOL (electric vertical take-off and landing) design for the urban air mobility market. Horizon has been developing the Cavorite X5 for the past two years. The concept for the X5 came from the company's initial prototype, the X3 — an amphibious design with a hybrid electric power system. “When we were asked to push the performance even further, we naturally began investigating distributed electric propulsion and the potential for eVTOL modification of the core X3 concept,” explained Robinson. “That's how the X5 The five-seat Cavorite X5 is powered by an electric motor coupled with a high-efficiency gas engine, but is ultimately built for fully electric flight. Horizon is building the aircraft to fly at speeds up to 350 kilometers per hour, with a 450-km range. The focus is to produce an aircraft “able to do real work in harsh environments,” including disaster relief, medevac, air cargo and personnel transport. Today, Robinson has his hands full with multiple patents pending, including a “fan-in-wing design” that would allow the Cavorite X5 to fly either like a conventional aircraft or an eVTOL when required. The X5 “flies like a normal aircraft for 99 percent of its mission,” said Robinson. The wing design “allows the aircraft to return to normal wing-borne lift after its vertical portion is complete; when moving forward, the wings close up and hide the vertical lift fans.” Horizon is working towards a large-scale prototype it hopes to have flying by the end of 2021. Robinson has become comfortable fielding questions based on skepticism. He's built an army of support from his highly-skilled network, including Virgin Galactic test pilot and close friend, Jameel Janjua. “Our team is extremely experienced, formed out of my father's previous custom aviation engineering business. We also have an individual leading the technical development who has designed, built and tested two novel aircraft designs from scratch. https://skiesmag.com/news/first-class-fighter-pilot-evtol-entrepreneur
