Fonctionnant à partir d’une broche unique avec une interface 1-Wire, ce circuit réduit la complexité d’interconnexion, simplifie les designs et minimise les coûts. Il garantit un haut niveau de sécurité à de nombreux systèmes comme des capteurs médicaux, des modules d’automates programmables industriels, ou des appareils grand-public.
\n"Le point faible d’un système d’authentification hôte-périphérique sécurisé à clé symétrique est typiquement le composant hôte, où les clés secrètes sont souvent insuffisamment protégées," affirme Christopher Tarnovsky, Vice-Président, Systèmes de sécurité à semiconducteurs chez IOActive. "L’utilisation d’une solution d’authentification à clé publique élimine ce risque au niveau sécurité."
\nL’utilisation de cryptographie ECSDA à clé publique réduit les coûts et facilite la gestion des clés, en évitant au contrôleur hôte d’enregistrer et de protéger la clé d’authentification comme l’exigent les solutions à base de cryptographie symétrique (à clé secrète) comparables. Ce circuit d’authentification utilise une paire de clés, l’une publique stockée dans le contrôleur hôte, et l’autre privée stockée dans le composant lui-même. L’avantage principal de la cryptographie ECDSA est de ne pas avoir à protéger la clé publique du côté du système hôte. Il est impératif, cependant, de protéger la clé privée stockée dans le circuit. Ceci se fait grâce aux technologies de sécurité Maxim DeepCover qui offrent à moindre coût le plus haut niveau de protection contre les attaques visant à révéler la clé privée, y compris les attaques invasives contre la puce elle-même. Ces technologies comprennent des techniques de routage et d’implémentation physique sophistiquées, des méthodes propriétaires additionnelles de protection de la clé privée, et des circuits actifs de protection anti-intrusion.
\n"Nos clients sont de plus en plus demandeurs des avantages que procure la cryptographie asymétrique à clé publique, pour leurs besoins d’authentification sécurisée," déclare Scott Jones, Directeur Exécutif de Maxim Integrated. "Nous avons réussi à combiner notre grande expertise en sécurité embarquée, avec plusieurs fonctionnalités déterminantes, pour offrir une solution dont la sécurité repose à la fois sur la protection physique et la cryptologie, facile à implanter dans une application finale."
\nEncapsulé en boîtiers TSOC 6 broches ou TDFN-EP 8 broches de 2 x 3 mm, ce composant est spécifié sur la plage de températures -40 °C à +85 °C.<\/p>\n<\/p>\n
