How Does Quantum Key Distribution Work?<\/span><\/strong><\/h2>\nQKD s'efforce de s'assurer que personne ne peut pirater le syst\u00e8me pendant que les informations sont transmises en se connectant directement au c\u00e2ble. L'exp\u00e9diteur QKD fonctionne pour transmettre des photons dans la fibre, les photons sont envoy\u00e9s un par un au r\u00e9cepteur. Chaque photon se voit attribuer une polarisation, une phase ou une position qui aide \u00e0 d\u00e9signer si ce photon va \u00eatre un 1 ou un 0 dans le syst\u00e8me binaire.<\/p>\n

<\/p>\n
Lorsque les donn\u00e9es sont envoy\u00e9es, ces photons peuvent \u00eatre 1 et 0 en m\u00eame temps. QKD fonctionne de sorte que lorsque ces photons sont arr\u00eat\u00e9s et observ\u00e9s, ils deviennent fixes. Cela fait en sorte que lorsque les donn\u00e9es sont ensuite envoy\u00e9es au r\u00e9cepteur, il ne s'agit que de b\u00eatises brouill\u00e9es et brouill\u00e9es. Cela signifie que le piratage est apparent imm\u00e9diatement afin que le r\u00e9cepteur puisse avertir l'exp\u00e9diteur que la ligne est exploit\u00e9e et accessible alors qu'elle ne devrait pas l'\u00eatre.<\/p>\n
Cela permet de savoir rapidement, presque imm\u00e9diatement, que la ligne est observ\u00e9e et que les transmissions doivent \u00eatre arr\u00eat\u00e9es afin qu'aucune donn\u00e9e ne soit corrompue ou intercept\u00e9e. Cela signifie que lorsque la ligne est exploit\u00e9e ou lorsqu'il devient \u00e9vident que les informations sont compromises, elles peuvent \u00eatre arr\u00eat\u00e9es afin qu'aucune autre information ne soit transmise. Rien d'autre n'est modifi\u00e9 ou accessible sans autorisation pour cette communication critique.<\/p>\n
Dans notre prochain blog, nous d\u00e9crivons les d\u00e9tails concernant l'utilit\u00e9 de la cryptographie quantique et comment, exactement, un cryptage des donn\u00e9es ad\u00e9quat est atteint. Le chiffrement, la fiabilit\u00e9 et la s\u00e9curit\u00e9 des donn\u00e9es restent au premier plan des utilisations critiques, qui peuvent inclure des utilisations de la Arm\u00e9e am\u00e9ricaine<\/a>, premiers intervenants, gouvernement et plus encore.
