Ces solutions de sécurité embarquées protègent les données sensibles par plusieurs couches de sécurité physique et autorisent un stockage hautement sécurisé des clés secrètes d’authentification. Grâce à l’utilisation d’un algorithme d’authentification SHA-256 sur base FIPS 180, ce dispositif combine authentification bidirectionnelle à cryptographie forte par challenge-réponse et chiffrement de petits messages.
\nL’authentification bidirectionnelle permet à l’hôte et au périphérique de s’authentifier mutuellement et de protéger l’IP présente dans le périphérique contre un hôte non-autorisé qui tenterait de modifier le fonctionnement de celui-ci. Ce circuit apporte un niveau de sécurité sans précédent pour de nombreuses applications, y compris les périphériques, les consommables, les capteurs, les équipements réseau, la gestion des licences ou des dispositifs industriels comme les automates programmables.
\n"Nous avons 20 ans d’expérience en recherche et développement dans la lutte contre les attaques d’intrusion, " déclare Scott Jones, Directeur Exécutif chez Maxim Integrated. "Grâce à plusieurs couches de sécurité et à SHA-256, nous pouvons rassurer les concepteurs sur le fait que leurs données sont en sécurité."
\nD’une programmation simple et totale, ce composant inclut 3 Kbits de mémoire et quatre modes de protection programmables par l’utilisateur. L’option SHA-256 lui assure un contrôle sécurisé des fonctionnalités finales par simple paramétrage. De plus, le service de pré-programmation en usine augmente encore le niveau de sécurité en évitant qu’une solution se trouve compromise par des intervenants de la chaîne d’approvisionnement.
\n"Les constructeurs de périphériques doivent sécuriser leurs matériels pour n’en laisser l’accès qu’aux seuls utilisateurs autorisés. La cryptographie symétrique est désormais couramment utilisée pour assurer la sécurité des systèmes, mais garder la clé de chiffrement symétrique en sécurité est la partie la plus critique de l’opération," explique Colin Barnden, Analyste Principal chez Semicast Research.
\nProposé en boîtier TDFN 8 broches, ce circuit est spécifié sur la gamme de température -40 °C à +85 °C.\n<\/p>\n
