Stockage hors ligne des clés cryptographiques produites et brevetées par Bank of America

Il est possible de l'utiliser pour des crypto-monnaies

L’Office américain des brevets et des marques (USPTO) a publié le document officiel dans lequel il a attribué un brevet à la Bank of America pour l’invention de la solution de stockage hors ligne à clés cryptographiques privées.

Un dispositif inviolable

Selon la Bank of America, les clés privées sont, dans la plupart des cas, connectées au stockage local du réseau public et sont donc vulnérables à divers détournements.

Ils souhaitaient développer une solution plus sécurisée pour le stockage de clés cryptographiques privées.

Leur dispositif nouvellement breveté est, prétendument, sensible à la fraude.

Toute tentative d’altération physique ou non physique entraînera la suppression de clés cryptographiques privées de la mémoire du stockage.

Totalement indépendant d’un nœud informatique nécessitant des clés de cryptographie privées stockées à l’intérieur, le dispositif non encore nommé permet aux clés privées d’être accessibles par le nœud, mais ne lui est pas communiqué lorsque le nœud exécute la routine d’authentification.

L’intérêt d’un tel système est de rendre les clés privées stockées dans les clés de périphérique moins sujettes à des actions malveillantes.

Brevets dans la communauté cryptographique

Bien que les brevets ne soient pas les mécanismes les plus populaires dans le monde de la crypto-monnaie open source, Bank of America a déjà déposé plus de 20 brevets.

La banque envisage l’avenir, ce qui s’explique mieux par le fait que ses brevets couvrent tous les domaines de l’activité de crypto-monnaie. Du traitement des paiements, y compris la conversion en temps réel et la validation des transactions, en passant par la détection des risques, aux solutions de stockage en ligne et désormais hors ligne.

Cependant, ce dernier brevet, bien qu’il mentionne plusieurs fois les crypto-monnaies, ne déclare pas explicitement être orienté vers les crypto-monnaie.

Comment les pionniers vont-ils réagir?

Tous ces brevets de Bank of America signifient que l’établissement financier prend au sérieux les nouvelles technologies.

Cependant, le monde des crypto-monnaies est toujours dominé par les projets open source, lancés pour la première fois par Bitcoin. Il semble que pratiquement personne dans les rangs de ces projets pionniers ne prenne ces brevets au sérieux, et ne les conteste pas juridiquement, même s’il a été établi que, dans certains cas, les brevets protègent la technologie existante.

Cela à l’exception du créateur d’Ethereum, Vitalik Buterin, qui a déjà pris des mesures contre un tel brevet.

Il sera intéressant de voir quelle approche pourra prévaloir dans les années à venir: celle qui partage les connaissances, ce qui crée un tout nouveau marché et une nouvelle industrie, ou celle où la jalousie conduit à garder les révélations pour soi.
