Abstract

La présente invention concerne des systèmes de communication de données et des protocoles de chiffrement asymétrique avec un appendice utilisés dans de tels systèmes. Fondamentalement, un système de signature numérique devrait être infalsifiable en cas d'attaque par message choisi. Actuellement, le système de signature généralement utilisé est l'algorithme de signature numérique à courbe elliptique (ECDSA) ; cependant, il nécessite une inversion d'une clé privée de session, ce qui peut être relativement intensif en calculs. Ainsi, une signature peut être vérifiée en générant un composant intermédiaire à partir d'un premier composant de signature et d'un message ; et en vérifiant la signature en comparant le composant intermédiaire et une coordonnée x récupérée de la clé publique de session.
