nLighten<\/strong><\/a>, plateforme europ\u00e9enne de datacenters edge, et Arqit Quantum Inc.<\/strong><\/a> (NASDAQ : ARQQ, ARQQW), leader mondial de la migration vers la cryptographie post-quantique (PQC) et du chiffrement r\u00e9sistant aux attaques quantiques, annoncent aujourd’hui avoir men\u00e9 avec succ\u00e8s une preuve de concept (POC) d\u00e9montrant que les organisations peuvent utiliser des services de cloud public tout en conservant le contr\u00f4le de leurs donn\u00e9es sensibles, de leurs cl\u00e9s de chiffrement et de leurs obligations de conformit\u00e9.<\/p>

Cette preuve de concept montre que les organisations n’ont plus \u00e0 choisir entre la capacit\u00e9 d’innovation et de mont\u00e9e en charge du cloud public et les exigences de souverainet\u00e9 impos\u00e9es aux charges de travail sensibles. Elles peuvent tirer parti des services cloud, des capacit\u00e9s d’intelligence artificielle et de ressources informatiques \u00e0 la demande tout en garantissant que leurs donn\u00e9es sensibles restent prot\u00e9g\u00e9es, auditables et gouvern\u00e9es au sein d’une infrastructure europ\u00e9enne de confiance.<\/p>

R\u00e9alis\u00e9e entre le Datacenter nLighten de Gen\u00e8ve et l’un des plus grands fournisseurs mondiaux de cloud hyperscale, cette d\u00e9monstration prouve qu’une charge de travail peut \u00eatre ex\u00e9cut\u00e9e dans un environnement de cloud public tout en restant ancr\u00e9e \u00e0 une infrastructure europ\u00e9enne souveraine. Les donn\u00e9es clients et les contr\u00f4les cryptographiques demeurent h\u00e9berg\u00e9s dans le site genevois de nLighten, tandis que la plateforme Symmetric Key Agreement (SKA-Platform\u2122) d’Arqit \u00e9tend cet environnement de confiance de mani\u00e8re s\u00e9curis\u00e9e jusqu’au cloud.<\/p>

Cette approche r\u00e9pond \u00e0 un d\u00e9fi croissant pour les organisations op\u00e9rant dans des secteurs fortement r\u00e9glement\u00e9s, notamment les services financiers, l’industrie pharmaceutique et le secteur public. Si les plateformes de cloud public offrent des avantages consid\u00e9rables en mati\u00e8re d’\u00e9volutivit\u00e9 et de flexibilit\u00e9, nombre d’organisations s’interrogent encore sur leur capacit\u00e9 \u00e0 pr\u00e9server leur souverainet\u00e9 lorsque des charges de travail sensibles sont ex\u00e9cut\u00e9es en dehors d’infrastructures qu’elles contr\u00f4lent directement.<\/p>

En associant leurs expertises, nLighten et Arqit proposent une troisi\u00e8me voie : permettre aux organisations de b\u00e9n\u00e9ficier des capacit\u00e9s du cloud public tout en conservant les contr\u00f4les essentiels \u00e0 leur souverainet\u00e9 gr\u00e2ce \u00e0 une infrastructure europ\u00e9enne physiquement souveraine et auditable. Les clients peuvent ainsi exploiter les capacit\u00e9s d’\u00e9lasticit\u00e9 du cloud, les services d’IA et les plateformes d’innovation sans d\u00e9placer leurs actifs les plus sensibles hors d’un environnement europ\u00e9en ma\u00eetris\u00e9. Ce mod\u00e8le contribue \u00e0 r\u00e9pondre aux exigences de conformit\u00e9, de s\u00e9curit\u00e9 et de souverainet\u00e9 tout en acc\u00e9l\u00e9rant les projets de transformation num\u00e9rique.<\/p>

La preuve de concept associe l’infrastructure souveraine de nLighten, les technologies cryptographiques d’Arqit et Intel Trust Domain Extensions (Intel TDX), une technologie de calcul confidentiel qui cr\u00e9e des environnements d’ex\u00e9cution prot\u00e9g\u00e9s au niveau mat\u00e9riel. Intel TDX isole les machines virtuelles et les conteneurs des administrateurs cloud, des charges de travail voisines et de tout acc\u00e8s non autoris\u00e9, prot\u00e9geant ainsi les donn\u00e9es pendant leur traitement. Les capacit\u00e9s de chiffrement post-quantique d’Arqit s\u00e9curisent \u00e9galement les donn\u00e9es \u00e9chang\u00e9es avec le cloud contre les futures attaques de type \u00ab harvest now, decrypt later \u00bb (\u00ab collecter aujourd’hui pour d\u00e9chiffrer demain \u00bb).<\/p>

Contrairement aux approches qui reposent principalement sur des garanties contractuelles ou sur des offres de cloud souverain propos\u00e9es par les hyperscalers eux-m\u00eames, cette solution s’appuie sur un datacenter europ\u00e9en physiquement souverain et pouvant \u00eatre audit\u00e9. nLighten fournit le socle d’infrastructure de confiance, tandis qu’Arqit prolonge ces garanties de souverainet\u00e9 jusqu’au cloud public gr\u00e2ce \u00e0 ses technologies cryptographiques.
Alors que les exigences r\u00e9glementaires en mati\u00e8re de souverainet\u00e9 num\u00e9rique se renforcent partout en Europe, cette solution conjointe aidera les organisations \u00e0 renforcer leur conformit\u00e9 vis-\u00e0-vis des futurs cadres r\u00e9glementaires, notamment le EU Cloud Sovereignty Framework, tout en continuant \u00e0 tirer parti des technologies cloud. \u00c0 la suite de cette preuve de concept r\u00e9ussie, ce mod\u00e8le devrait \u00eatre d\u00e9ploy\u00e9 dans l’ensemble du r\u00e9seau de plus de 30 datacenters edge exploit\u00e9s par nLighten dans sept pays europ\u00e9ens.<\/p>

Dame Dawn Child, CEO de nLighten, d\u00e9clare :<\/strong> \u00ab Nos clients souhaitent de plus en plus exploiter l’intelligence artificielle, les analyses avanc\u00e9es et les services cloud natifs. Pourtant, beaucoup \u00e9voluent dans des environnements hautement r\u00e9glement\u00e9s o\u00f9 le contr\u00f4le des donn\u00e9es est une exigence absolue. Cette preuve de concept d\u00e9montre qu’ils n’ont plus \u00e0 choisir entre innovation et souverainet\u00e9. En ancrant leurs charges de travail dans une infrastructure europ\u00e9enne de confiance, ils peuvent d\u00e9sormais concilier les deux. \u00bb<\/em><\/p>

Andy Leaver, CEO d’Arqit, ajoute :<\/strong> \u00ab Pendant trop longtemps, les organisations ont \u00e9t\u00e9 contraintes de choisir entre conserver le contr\u00f4le de leurs donn\u00e9es sensibles et b\u00e9n\u00e9ficier de la puissance et de l’innovation du cloud public. Notre collaboration avec nLighten d\u00e9montre qu’il existe une troisi\u00e8me voie. En combinant une infrastructure europ\u00e9enne souveraine, le calcul confidentiel et une cryptographie r\u00e9sistante aux attaques quantiques, les organisations peuvent continuer \u00e0 exploiter les services de cloud public tout en gardant davantage de contr\u00f4le sur la protection de leurs donn\u00e9es. Plus important encore, cette approche apporte des garanties techniques, et non de simples garanties contractuelles, leur permettant de renforcer leur souverainet\u00e9 sans freiner leur innovation. \u00bb <\/em><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
