Abstract[English]
A method and system for generating and verifying a digital signature, the method and system comprising sharing, between a signing node and a verifying node, a message in which the signing node is to issue a digital signature, performing, by the signing node, a first number of operations to generate the digital signature featuring a redundancy, generating, by the signing node, a shortened digital signature. The transforming of the digital signature to the shortened digital signature includes omitting the redundancy, transmitting, by the signing node to the verifying node, the shortened digital signature. The verifying node is configured to perform a second number of operations to recover the redundancy and generate the digital signature from the shortened digital signature, and verifying, by the verifying node, the digital signature with respect to the message.[French]
L'invention concerne un procédé et un système permettant de générer et de vérifier une signature numérique, le procédé et le système consistant à : partager, entre un nœud de signature et un nœud de vérification, un message dans lequel le nœud de signature doit émettre une signature numérique ; réaliser, au moyen du nœud de signature, un premier nombre d'opérations pour générer la signature numérique présentant une redondance ; générer, au moyen du nœud de signature, une signature numérique raccourcie. La transformation de la signature numérique en signature numérique raccourcie consiste à omettre la redondance et à transmettre la signature numérique raccourcie au nœud de vérification au moyen du nœud de signature. Le nœud de vérification est configuré pour réaliser un second nombre d'opérations afin de récupérer la redondance et de générer la signature numérique à partir de la signature numérique raccourcie, et pour vérifier la signature numérique par rapport au message au moyen du nœud de vérification.
