Au fur et \u00e0 mesure que les voitures gagnent en sophistication au niveau fonctionnalit\u00e9s, les risques en mati\u00e8re de s\u00e9curit\u00e9 augmentent aussi. Les constructeurs d\u2019automobiles ont recours \u00e0 l’authentification pour s’assurer que seuls des composants certifi\u00e9s par les fabricants puissent \u00eatre connect\u00e9s en toute s\u00e9curit\u00e9 aux syst\u00e8mes du v\u00e9hicule, tout en r\u00e9duisant les risques d’attaque de logiciels malveillants. Cependant, les micro-contr\u00f4leurs totalement s\u00e9curis\u00e9s pr\u00e9sentent en g\u00e9n\u00e9ral une empreinte assez grande, et n\u00e9cessitent des \u00e9quipes de d\u00e9veloppement logiciel pour cr\u00e9er, tester rigoureusement et d\u00e9boguer le code utilis\u00e9. Plus le volume de code est important, plus le risque de bogues ou de malware susceptibles de nuire aux performances est \u00e9lev\u00e9.<\/p>\n

L’authentificateur DeepCover DS28C40 est le seul authentificateur r\u00e9pondant \u00e0 la norme AEC-Q100 Classe 1. Il remplace les approches \u00e0 base de micro-contr\u00f4leurs, et r\u00e9duit \u00e0 la fois la complexit\u00e9 de la conception syst\u00e8me et les efforts de d\u00e9veloppement de code associ\u00e9s. L’authentificateur emp\u00eache le vol de composants de grande valeur, tels que les modules d’\u00e9clairage avant. Il assure aussi un chiffrement asym\u00e9trique ECDSA \u00e0 cl\u00e9 publique\/priv\u00e9e (courbe ECC-P256), et d’autres algorithmes d’authentification \u00e0 cl\u00e9 int\u00e9gr\u00e9s dans le CI \u00e9vitent aux fabricants le d\u00e9veloppement de code propri\u00e9taire au niveau du dispositif. Cet algorithme ainsi que d’autres algorithmes int\u00e9gr\u00e9s au CI d’authentification offrent la meilleure d\u00e9fense contre l\u2019utilisation de composants non-autoris\u00e9s susceptibles de compromettre les performances, la s\u00e9curit\u00e9 et l’int\u00e9grit\u00e9 des donn\u00e9es. Le DS28C40 se pr\u00e9sente en bo\u00eetier TDFN compact de 4 mm x 3 mm, et fonctionne dans la plage de temp\u00e9rature -40 \u00b0C \u00e0 +125 \u00b0C. 
\n\u00ab Au fur et \u00e0 mesure que le contenu \u00e9lectronique augmente dans les plateformes automobiles, la menace que repr\u00e9sente l\u2019utilisation de composants de qualit\u00e9 inf\u00e9rieure susceptibles de compromettre la s\u00e9curit\u00e9 et la performance des v\u00e9hicules augmente elle aussi, \u00bb d\u00e9clare Tanner Johnson, Analyste Senior IoT et Connectivit\u00e9 chez IHS Markit, maintenant appartenant \u00e0 Informa Tech. \u00ab Les grands fabricants s’inqui\u00e8tent \u00e0 juste titre de ces menaces, et toute technologie de s\u00e9curit\u00e9 bas\u00e9e sur des normes permettant d\u2019emp\u00eacher l’utilisation de composants non-certifi\u00e9s, tout en r\u00e9alisant des \u00e9conomies, suscite un fort int\u00e9r\u00eat des concepteurs. \u00bb
\n\u00ab Les \u00e9quipementiers automobiles et les sous-traitants de rang 1 sont confront\u00e9s \u00e0 des contraintes de temps et de ressources lorsqu’il s’agit de s\u00e9curiser des syst\u00e8mes \u00e9lectroniques complexes, \u00bb d\u00e9clare Michael Haight, Directeur S\u00e9curit\u00e9 embarqu\u00e9e chez Maxim Integrated. \u00ab Nos nouveaux CI d’authentification miniatures les aident \u00e0 mettre en \u0153uvre la crypto-s\u00e9curit\u00e9 la plus avanc\u00e9e disponible, sans faire appel \u00e0 davantage de personnel pour \u00e9crire et d\u00e9boguer le code g\u00e9n\u00e9ralement indispensable en cas d\u2019approches d\u00e9pendantes du micro-contr\u00f4leur et du logiciel. \u00bb <\/p>\n
