Title
(EN) METHOD AND SYSTEM FOR IMPLEMENTING A DIGITAL SIGNATURE
(FR) PROCEDE ET SYSTEME DE MISE EN OEUVRE D'UNE SIGNATURE NUMERIQUE
Abstract
(EN)
Method for digitally signing an electronic form in a secure manner by means of a mobile station. In the method, the material to be signed, which comprises a form, its identifier, shared information, and/or essential information added to it, is transferred to the mobile station, a first hash code (H1) is computed from the material to be signed, the hash code is added to the material for transfer into the mobile station, the material transferred into the mobile station is signed digitally by means of the mobile station and the authenticity of the signed and transferred material is verified by comparing the signed hash code with the hash code computed from the material before the signature. Thanks to the invention, a mobile station can be safely used for digital signature in various applications.

L'invention concerne un procédé de signature numérique d'un formulaire électronique, de manière sûre, au moyen d'une station mobile. Dans ledit procédé, les documents à signer, qui sont constitués d'un formulaire, de son identifiant, d'informations partagées et/ou d'informations essentielles ajoutées à ces dernières, sont transférés à la station mobile, un premier code de hachage (H1) est calculé à partir des documents à signer, le code de hachage est ajouté aux documents pour être transféré dans la station mobile, les documents transférés dans la station mobile sont signés numériquement au moyen de la station mobile et l'authenticité des documents signés et transférés est vérifiée par comparaison du code de hachage signé et le code de hachage calculé à partir des documents avant la signature. Le procédé et le système de l'invention permettent à une station mobile d'être utilisée en toute sécurité pour la signature numérique dans diverses applications.
