Abstract

L'invention porte sur un terminal en nuage. Le terminal en nuage comprend deux unités d'interface réseau ou plus et une unité de commande connectée aux deux unités d'interface réseau ou plus. Les deux unités d'interface réseau ou plus sont utilisées pour établir une connexion à un réseau informatique, et chaque unité d'interface réseau correspond à au moins un réseau informatique. L'unité de commande impose à l'une des deux unités d'interface réseau ou plus d'être dans un état actif, et impose aux autres unités d'interface réseau d'être dans un état inactif. Etant donné qu'une seule unité d'interface réseau est dans l'état actif pour établir une connexion de communication entre l'unité d'interface réseau et un réseau informatique correspondant, des informations présentes dans un réseau informatique physiquement isolé ne peuvent pas fuir vers un autre réseau informatique physiquement isolé par rayonnement électromagnétique, et l'autre réseau informatique physiquement isolé ne peut pas faire invasion dans ce réseau informatique physiquement isolé par rayonnement électromagnétique, ce qui permet ainsi d'améliorer la sécurité du réseau informatique.
