Abstract[English]
The invention relates generally to cryptography in secure microchips using a password authentication scheme. More specifically, the invention is directed to a uniquely configured electronic hardware component and method of usage for providing secure password initialization and branch-free password authentication. The electronic hardware component together with a method of usage results in a system that, upon correctly entering a possibly low-entropy secret, such as a password, outputs a high-entropy cryptographic key while allowing only a limited number of attempts to enter the correct password. The invention effectively enforces the limit on the number of password attempts without employing a numeric counter, thus eliminating the use of conditional branching operations and making it suitable for use in secure tamper-resistant integrated circuits.[French]
L'invention concerne de manière générale la cryptographie dans des micropuces sécurisées à l'aide d'un schéma d'authentification de mot de passe. Plus précisément, l'invention concerne un composant matériel électronique doté d'une configuration unique et un procédé d'utilisation permettant d'assurer une initialisation sécurisée des mots de passe et une authentification par mot de passe sans branchement. Le composant matériel électronique, associé à un procédé d'utilisation, donne naissance à un système qui, après la saisie correcte d'un secret à faible entropie, tel qu'un mot de passe, génère une clé cryptographique à forte entropie tout en n'autorisant qu'un nombre limité de tentatives pour saisir le mot de passe correct. Cette invention permet d'appliquer efficacement la limite du nombre de tentatives de mot de passe sans recourir à un compteur numérique, éliminant ainsi le recours à des opérations de branchement conditionnel et la rendant ainsi adaptée à une utilisation dans des circuits intégrés sécurisés et inviolables.
